If you run into problems when using Windows Update, start with the following steps:

  1. Run the built-in Windows Update troubleshooter to fix common issues. Navigate to Settings > Update & Security > Troubleshoot > Windows Update.

  2. Install the most recent Servicing Stack Update that matches your version of Windows from the Microsoft Update Catalog. See Servicing stack updates for more details on servicing stack updates.

  3. Make sure that you install the latest Windows updates, cumulative updates, and rollup updates. To verify the update status, refer to the appropriate update history for your system:

    • Windows 10, version 2004 and Windows Server, version 2004
    • Windows 10, version 1909 and Windows Server, version 1909
    • Windows 10, version 1903 and Windows Server, version 1903
    • Windows 10, version 1809 and Windows Server 2019
    • Windows 10, version 1803
    • Windows 10, version 1709
    • Windows 10, version 1703
    • Windows 10 and Windows Server 2016
    • Windows 8.1 and Windows Server 2012 R2
    • Windows Server 2012
    • Windows 7 SP1 and Windows Server 2008 R2 SP1

Advanced users can also refer to the log generated by Windows Update for further investigation.

You might encounter the following scenarios when using Windows Update.

Why am I offered an older update?

The update that is offered to a device depends on several factors. The following are some of the most common attributes:

  • OS Build
  • OS Branch
  • OS Locale
  • OS Architecture
  • Device update management configuration

If the update you’re offered isn’t the most current available, it might be because your device is being managed by a WSUS server, and you’re being offered the updates available on that server. It’s also possible, if your device is part of a deployment group, that your admin is intentionally slowing the rollout of updates. Since the deployment is slow and measured to begin with, all devices will not receive the update on the same day.

My device is frozen at scan. Why?

The Settings UI communicates with the Update Orchestrator service that in turn communicates with to Windows Update service. If these services stop unexpectedly, then you might see this behavior. In such cases, follow these steps:

  1. Close the Settings app and reopen it.

  2. Start Services.msc and check if the following services are running:

    • Update State Orchestrator
    • Windows Update

Feature updates are not being offered while other updates are

Devices running Windows 10, version 1709 through Windows 10, version 1803 that are configured to update from Windows Update (including Windows Update for Business) are able to install servicing and definition updates but are never offered feature updates.

Checking the WindowsUpdate.log reveals the following error:

The 0x80070426 error code translates to:

ERROR_SERVICE_NOT_ACTIVE - # The service has not been started. 

Microsoft Account Sign In Assistant (MSA or wlidsvc) is the service in question. The DCAT Flighting service (ServiceId: 855E8A7C-ECB4-4CA3-B045-1DFA50104289) relies on MSA to get the global device ID for the device. Without the MSA service running, the global device ID won’t be generated and sent by the client and the search for feature updates never completes successfully.

To resolve this issue, reset the MSA service to the default StartType of «manual.»

Windows Update uses WinHttp with Partial Range requests (RFC 7233) to download updates and applications from Windows Update servers or on-premises WSUS servers. Therefore proxy servers on the network must support HTTP RANGE requests. If a proxy was configured in Internet Explorer (User level) but not in WinHTTP (System level), connections to Windows Update will fail.

To fix this issue, configure a proxy in WinHTTP by using the following netsh command:

netsh winhttp set proxy ProxyServerName:PortNumber 

Note

You can also import the proxy settings from Internet Explorer by using the following command: netsh winhttp import proxy source=ie

If downloads through a proxy server fail with a 0x80d05001 DO_E_HTTP_BLOCKSIZE_MISMATCH error, or if you notice high CPU usage while updates are downloading, check the proxy configuration to permit HTTP RANGE requests to run.

You might choose to apply a rule to permit HTTP RANGE requests for the following URLs:

*.download.windowsupdate.com
*.dl.delivery.mp.microsoft.com
*.delivery.mp.microsoft.com

If you can’t allow RANGE requests, you’ll be downloading more content than needed in updates (as delta patching will not work).

The update is not applicable to your computer

The most common reasons for this error are described in the following table:

Cause Explanation Resolution
Update is superseded As updates for a component are released, the updated component will supersede an older component that is already on the system. When this occurs, the previous update is marked as superseded. If the update that you’re trying to install already has a newer version of the payload on your system, you might receive this error message. Check that the package that you are installing contains newer versions of the binaries. Or, check that the package is superseded by another new package.
Update is already installed If the update that you’re trying to install was previously installed, for example, by another update that carried the same payload, you may encounter this error message. Verify that the package that you are trying to install was not previously installed.
Wrong update for architecture Updates are published by CPU architecture. If the update that you’re trying to install does not match the architecture for your CPU, you may encounter this error message. Verify that the package that you’re trying to install matches the Windows version that you are using. The Windows version information can be found in the «Applies To» section of the article for each update. For example, Windows Server 2012-only updates cannot be installed on Windows Server 2012 R2-based computers.
Also, verify that the package that you are installing matches the processor architecture of the Windows version that you are using. For example, an x86-based update cannot be installed on x64-based installations of Windows.
Missing prerequisite update Some updates require a prerequisite update before they can be applied to a system. If you are missing a prerequisite update, you may encounter this error message. For example, KB 2919355 must be installed on Windows 8.1 and Windows Server 2012 R2 computers before many of the updates that were released after April 2014 can be installed. Check the related articles about the package in the Microsoft Knowledge Base (KB) to make sure that you have the prerequisite updates installed. For example, if you encounter the error message on Windows 8.1 or Windows Server 2012 R2, you may have to install the April 2014 update 2919355 as a prerequisite and one or more pre-requisite servicing updates (KB 2919442 and KB 3173424).
To determine if these prerequisite updates are installed, run the following PowerShell command:
get-hotfix KB3173424,KB2919355, KB2919442.
If the updates are installed, the command will return the installed date in the InstalledOn section of the output.

Error that you might see in Windows Update logs:

DownloadManager    Error 0x800706d9 occurred while downloading update; notifying dependent calls. 

Or

[DownloadManager] BITS job {A4AC06DD-D6E6-4420-8720-7407734FDAF2} hit a transient error, updateId = {D053C08A-6250-4C43-A111-56C5198FE142}.200 <NULL>, error = 0x800706D9 

Or

DownloadManager [0]12F4.1FE8::09/29/2017-13:45:08.530 [agent]DO job {C6E2F6DC-5B78-4608-B6F1-0678C23614BD} hit a transient error, updateId = 5537BD35-BB74-40B2-A8C3-B696D3C97CBA.201 <NULL>, error = 0x80D0000A 

Go to Services.msc and ensure that Windows Firewall Service is enabled. Stopping the service associated with Windows Firewall with Advanced Security is not supported by Microsoft. For more information, see I need to disable Windows Firewall.

Issues arising from configuration of conflicting policies

Windows Update provides a wide range configuration policy to control the behavior of the Windows Update service in a managed environment. While these policies let you configure the settings at a granular level, misconfiguration or setting conflicting policies may lead to unexpected behaviors.

For more information, see How to configure automatic updates by using Group Policy or registry settings for more information.

Device cannot access update files

Ensure that devices can reach necessary Windows Update endpoints through the firewall. For example, for Windows 10, version 2004, the following protocols must be able to reach these respective endpoints:

Protocol Endpoint URL
TLS 1.2 *.prod.do.dsp.mp.microsoft.com
HTTP emdl.ws.microsoft.com
HTTP *. dl.delivery.mp.microsoft.com
HTTP *.windowsupdate.com
HTTPS *.delivery.mp.microsoft.com
TLS 1.2 *.update.microsoft.com
TLS 1.2 tsfe.trafficshaping.dsp.mp.microsoft.com

Note

Be sure not to use HTTPS for those endpoints that specify HTTP, and vice versa. The connection will fail.

The specific endpoints can vary between Windows client versions. See, for example, Windows 10 2004 Enterprise connection endpoints. Similar articles for other Windows client versions are available in the table of contents nearby.

Updates aren’t downloading from the intranet endpoint (WSUS or Configuration Manager)

Windows client devices can receive updates from a variety of sources, including Windows Update online, a Windows Server Update Services server, and others. To determine the source of Windows Updates currently being used on a device, follow these steps:

  1. Start Windows PowerShell as an administrator.
  2. Run $MUSM = New-Object -ComObject «Microsoft.Update.ServiceManager».
  3. Run $MUSM.Services.

Check the output for the Name and OffersWindowsUPdates parameters, which you can interpret according to this table.

Output Meaning

— The client is configured to receive updates from WSUS.
— Name: Windows Update
— OffersWindowsUpdates: True
— The source is Windows Update.
— The client is configured to receive updates from Windows Update Online.

You have a bad setup in the environment

In this example, per the Group Policy set through registry, the system is configured to use WSUS to download updates (note the second line):

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU] 
"UseWUServer"=dword:00000001

From Windows Update logs:

2018-08-06 09:33:31:085  480 1118 Agent ** START **  Agent: Finding updates [CallerId = OperationalInsight  Id = 49]

2018-08-06 09:33:32:554  480 1118 Agent **  END  **  Agent: Finding updates [CallerId = OperationalInsight  Id = 49] 

In the above log snippet, we see that the Criteria = "IsHidden = 0 AND DeploymentAction=*". «*» means there is nothing specified from the server. So, the scan happens but there is no direction to download or install to the agent. So it just scans the update and provides the results.

As shown in the following logs, automatic update runs the scan and finds no update approved for it. So it reports there are no updates to install or download. This is due to an incorrect configuration. The WSUS side should approve the updates for Windows Update so that it fetches the updates and installs them at the specified time according to the policy. Since this scenario doesn’t include Configuration Manager, there’s no way to install unapproved updates. You’re expecting the operational insight agent to do the scan and automatically trigger the download and installation but that won’t happen with this configuration.

High bandwidth usage on Windows client by Windows Update

Users might see that Windows is consuming all the bandwidth in the different offices under the system context. This behavior is by design. Components that might consume bandwidth expand beyond Windows Update components.

The following group policies can help mitigate this situation:

  • Blocking access to Windows Update servers: Policy Turn off access to all Windows Update features (Set to enabled)
  • Driver search: Policy Specify search order for device driver source locations (Set to «Do not search Windows Update»)
  • Windows Store automatic update: Policy Turn off Automatic Download and Install of updates (Set to enabled)

Other components that connect to the internet:

  • Windows Spotlight: Policy Configure Windows spotlight on lock screen (Set to disabled)
  • Consumer experiences: Policy Turn off Microsoft consumer experiences (Set to enabled)
  • Background traffic from Windows apps: Policy Let Windows apps run in the background

    Microsoft Windows Update Overview, All You Need To Know

    Windows Update is a free computer service provided by Microsoft that provides Operating System (OS) patches and service packs to computers running the many versions of Microsoft Windows.

    These updates are either enhancements or corrections to OS features, or security updates meant to protect your system from malicious attacks and malware.

    Reliability, security and performance are the the most important reasons that all computers running MS Windows should use Windows Update.

    An option called Microsoft Update can be configured in this service to also provide updates for several other Microsoft software applications, such as the MS Office suite or the latest Internet Explorer browser.

    Windows Update Details

    Windows Update always downloads these vital updates automatically. But, you can set up the service to install all or some of the updates as they are received, or to let you review the pending updates before you decide on which to install. Windows Update will provide a Windows PC with:

    • The most recent security updates for your OS
    • OS updates to improve performance and reliability
    • Device drivers from both Microsoft and other companies

    Upgrades are different from updates, in that upgrades are new versions of application software, or of the OS itself. Minor version upgrades may be available from Microsoft through Windows Update, but major version upgrades would likely involve a new software purchase, perhaps at a lower upgrade price.

    The Microsoft Download Center is a website that contains all the elements of the Microsoft software updating, upgrading, and downloading programs that are both necessary and useful for the continuing operation of your Windows operating system.

    The web site contains sub-sites for:

    • Microsoft Windows Update
    • Microsoft Download Notifications
    • Microsoft Store (for both Windows software and MS Office software)
    • Microsoft OS Service Packs
    • Microsoft Technologies (focusing on Internet Explorer, DirectX, and Windows 7)

    Note: Microsoft started to push updates via its Microsoft Update Catalog website recently. Updates offered on the site are downloaded and installed manually.

    Timeline for Windows Updates

    Patch Tuesday, the second Tuesday of every month, is the day that security updates are globally distributed via Windows Update and the Internet. Emergency security updates, however, may be distributed any time it is deemed necessary because of a newly discovered exploit that targets MS Windows.

    The Internet is the preferred avenue of distribution for Windows Update to PCs, but Microsoft also provides other means for updates to be received by computers with no Internet connection. However, the PC interface controlling receipt of distributions is different for the various versions of Windows:

    • Customer access at the MS Windows Update website (Windows 98, Windows XP, Windows ME, Windows 2000)
    • Control Panel applet (Windows 7, Windows Vista)

    With any OS before Windows Vista, an update that required a PC reboot would display a dialog box every few minutes which would request that the machine be rebooted.

    In Windows Vista and Windows 7, the same dialog box allows entry of a time period, up to four hours, before another dialog box appears — however, some updates that require a reboot may create a displayed countdown, at the end of which the computer will reboot no matter what the current user on the PC is doing, causing possible problems if data is not saved or the user is in the middle of a game.

    Tip: It is possible to prevent the forced shutdown manually with the command shutdown –a in the Windows command line.

    If there is an unexpected PC shutdown in the middle of an update download, Windows Update makes use of a feature of Windows system files called Transactional NTFS to enable the system to recover cleanly and to ensure that partially loaded updates are fully loaded before being applied.

    1. Disable automatic reboot after Windows Updates in Windows 10

    Windows Update Levels

    There are three levels Of Window Updates: Optional, Recommended, and Important.

    Optional Updates, are, of course, optional, that a user can review, and choose to install or not to install. Included are:

    • Offers for new or trial MS Windows software
    • Updated device drivers from non-Microsoft companies (a driver may be promoted to Recommended level if your system is missing that driver and needs it, or the new driver has major feature revisions). Guide to block device driver updates via Windows Update.

    Recommended Updates are those enhance the computing OS experience, improving performance. Included are:

    • Compatibility updates
    • Revised contents of Help files
    • New features for the Windows OS
    • New features for other Microsoft software

    Important updates are oriented more toward security and reliability. Included are:

    • Security and privacy updates
    • Significant reliability updates
    • Updates for detection of non-genuine Microsoft software
    • Verification of copyright-protected media

    Options can be set to download and install automatically both the Important updates (set as a default) and the Recommended updates — with Windows XP, however, only the updates that are classified High-Priority will be downloaded and installed automatically.

    Cumulative Updates

    Microsoft started to push out so-called cumulative updates with the release of Windows 10. The company switched to a similar system on Windows 7 and 8 in 2016.

    On Windows 10, PCs are assigned to a servicing channel which determines the updating procedure. Home versions, and all unmodified Pro, Education and Enterprise versions are assigned to the Semi-Annual channel.

    Current Terminolog:

    • Semi-Annual Channel — replaced Current Branch and Current Branch for Business. Twice a year release target (March and September), and supported for 18 months in total.

    Previous Terminology:

    • Current Branch — updates are downloaded and installed when they become available.
    • Current Branch for Business — not available in Windows 10 Home. Defer updates up to 4 months.
    • Long Time Servicing Branch — not available in Home or Pro.

    On Windows 7 and Windows 8, two update packages are provided each month:

    1. Security Only Quality Update only include security updates released in the month mentioned in the update title.
    2. Security Monthly Quality Rollup includes security updates and non-security updates. Cumulative.
    Update Classification Contents Includes IE Not applicable Release
    Security Monthly Quality Rollup
    (aka the Monthly Rollup)
    Security Updates New security fixes + non-security fixes from latest Preview Rollup + all previous Monthly Rollups Yes If a later Monthly Rollup is installed Update Tuesday (2nd Tuesday)
    Security Only Quality Update
    (aka the Security Only update)
    Security Updates New security fixes(not including IE fixes) No If a Monthly Rollup (current or later month) is installed Update Tuesday (2nd Tuesday)
    Preview of Monthly Quality Rollup
    (aka the Preview Rollup)
    Updates New non-security fixes + all previous Monthly Rollups Yes If a later Monthly Rollup or Preview Rollup is installed 3rd Tuesday
    Cumulative Security Update for Internet Explorer Security Updates Fixes for IE11 (IE10 on Windows Server 2012) Yes If a Monthly Rollup (current or later month) or IE Update (later month) is installed Update Tuesday (2nd Tuesday)

    Disabling Windows Update

    If you want to disable Windows Update, you can disable the service for the PC, or by user-name. For an entire PC, the Group Policy Editor is used to disable Windows Update in the general User Configuration.

    For individual users, REGEDIT is used to disable Windows Update in a User Registry key:

    • In HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer, create a new DWORD key.
    • Make the Name of the key NoWindowsUpdate, and set the Value to 1.
    • Whenever this user attempts to start Windows Update, an error message will display.

    The following tools and articles may also be useful:

    • Block Windows Updates with Windows 10 Update Switch
    • Control Windows Updates with W10Privacy Tool

    After Updates

    Once you have made sure that updates work fine and don’t cause any issues, you may want to run clean up operations to remove files that are no longer needed. This may free up Gigabytes of disk space depending on the update.

    • Run Disk Cleanup after the Windows 10 upgrade to free space
    • Save lots of disk space with Microsoft’s new Windows Update Cleanup tool

    Troubleshooting Windows Update Errors

    Windows Update is an essential maintenance element for the optimum performance of your computer. However, errors can occur during the normal operation of this important service. Here’s where we describe what measures you can take if Windows Update stops working on your computer system.

    Measure #0: Check Date and Time

    Make sure the date and time of the operating system is set correctly. Simply move the mouse cursor over the time in the system tray area to verify that.

    Windows Update may not work properly if the date or time is not set correctly.

    Measure #1: Check Internet Connection

    Windows Update depends a great deal on Internet connectivity. First step is to see if you have full Internet connectivity by connecting to several web sites — if able to do so, the next step is to check the reliability of the connection, by checking email, signing on to forums, and looking at videos. If connection seems reliable, wait fifteen minutes and try running Windows Update again.

    Measure #2: Start Supporting Services

    Windows Update depends on several other services that also must be running on your PC. Check for these other services by clicking on Start, typing SERVICES.MSC, and pressing ENTER. Check in the display of services at the right for the names:

    • Background Intelligent Transfer Service
    • Cryptographic Services
    • Automatic Updates
    • Event Log

    For each one whose Status is not Running, double-click to make the General tab appear — Startup Type should be Automatic. Click the Start button to change the service to a Running status.

    Measure #3: Check Firewalls

    The next measure to make sure the Windows Firewall is running, and not a firewall from a company other than Microsoft. To ensure continuous firewall protection, turn on the MS Firewall before turning off any other firewall.

    • First, enable the Windows firewall by clicking Start…Run, typing FIREWALL.CPL in the Open box, and pressing ENTER.
    • Second, disable any other firewall that may be running on your PC.

    Now, try running Windows Update again.

    Measure #4: Check Anti-Virus

    Start the Security Center applet in the Control Panel, and turn off or disable the anti-virus application listed under either ‘Virus Protection’ or ‘Malware Protection’ section. Try running Windows Update again, and then immediately go back to the Security Center and enable the anti-virus application that had been disabled. Be careful with this measure — temporarily turning off your anti-virus application may allow Windows Update to start up, but, at the same time, doing so will leave your PC vulnerable.

    Measure #5: Check Accelerators

    Check to see if your PC has any Internet accelerators installed to increase the performance of Internet access. Such software can interfere with the operation of Windows Update. Consult the documentation for those accelerators to either disable or uninstall the software. Check the operation of Windows Update again.

    Measure #6: Reset the Windows Update Folder

    A corrupt file within the Windows Update distribution folder may be causing a problem with Windows Update. The solution is to reset the folder.

    • Open a command prompt with the CMD, making sure the command is being Run as Administrator.
    • In the CMD prompt, type net stop WuAuServ and press enter (this action stops the Windows Update service).
    • Wait for a response that the Windows Update service was successfully stopped.
    • Type %windir% in the OPEN box of the Start Menu, and press Enter.
    • Right-click the SoftwareDistribution folder, and select Rename.
    • Rename the folder to SoftwareDistributionOLD (saving the original contents so that you can revert to them if needed by renaming to the original name).
    • Back in the CMD window, type «net start WuAuServ» (without quotes). and press ENTER.
    • Use the same steps you used in Measure #2 to check to see if the Windows Update service is running.

    Try to run Windows Update — if unsuccessful, rename the SoftwareDistributionOLD folder back to its original name of SoftwareDistribution.

    Measure #7: Check System Files

    System files may have become corrupted, and you may need to scan the Windows system files to see if they are still correct and accurate.

    • In a CMD box (started up in the same way as described in Measure #6), type «sfc /scannow» (without quotes), and press ENTER.
    • When the scan is done, close the CMD box, and reboot your PC.

    Try running Windows Update when your PC comes back up.

    Measure #8: Verify BITS Files

    BITS stands for Background Intelligence Transfer Service, and these files are essential to the functioning of Windows Update. It is possible the BITS files on your PC may be corrupted. You can download a BITS repair tool at the MS website:

    32-bit Windows

    64-bit Windows

    Once you’ve downloaded and installed the BITS Repair Tool on your PC, reboot and let the tool run.

    Measure #9: Check Support Sites

    Check these two Microsoft support websites for descriptions of problems that may be similar to yours, with possible solutions.

    FAQ
    Problems

    Measure #10: System Update Readiness Tool

    Microsoft has released the System Update Readiness Tool for its operating systems that aim to repair issues related to the operating system’s automatic update functionality.

    If you are experiencing issues, download the tool for your system and run it afterwards to resolve issues that you may experience.

    • Windows Vista 32-bit
    • Windows Vista 64-bit
    • Windows 7 32-bit
    • Windows 7 64-bit

    If this last measure does not help you to restore Windows Update to its proper functioning, then contact MS Customer Support.

    Update: Microsoft released a new Windows Update repair tool that you can download as well to fix update related issues. Check out Fix Windows Update issues with Reset Windows Update Agent as well.

    [SOLVED] One of the Update Services is not Running Properly in Windows Update

    By Kevin Arrows March 31, 2021

    4 minutes read

    Kevin is a certified Network Engineer

    One of the Windows update services might not run if an application on your system (like StopUpdates10Guard) is hindering the operation of the update modules of your system. Moreover, the wrong configuration of the Windows Update or BITS services may also cause the error under discussion.

    The issue arises when the Windows update fails to check for the latest available updates with the following message:

    “Error encountered. One of the update services is not running properly, but you can try to run a troubleshooter to fix the problem. Go to Start button > Settings > Update & Security > Troubleshoot, and then select Windows Update.”

    Windows Update: One of the Update Services is not Running Properly

    But when the user launches the troubleshooter to fix the Windows Update services issue, the troubleshooter does not work.

    Before moving on to fix the Windows update service issue, check if you can update your system on another network. For example, if you are using a Wi-Fi connection, then check if trying an ethernet connection resolves the issue. In some cases, the users reported that the issue was occurring on a cellular-based or metered network, so, make sure that is not the case with you.

    Solution 1: Set Startup Type of the BITS and Windows Update Service to Automatic

    The Windows update issue may arise if any of the essential update services are in an error state or disabled. In this context, setting the Startup type of these Update services (i.e., BITS and Windows Update service) to Automatic may solve the problem.

    1. Press the Windows key and in the Windows search, type: Services. Now, hover your mouse over the result of Services, and in the right pane of the Start menu, choose Run as Administrator.Open Services as Administrator
    2. Now, double-click on the Windows Update service (or right-click and choose Properties) and change its Startup Type to Automatic. Open Properties of Windows Update Service
    3. Then click on the Start button and apply the changes.Set the Startup Type of the Windows Update Service to Automatic and Start it
    4. After that, repeat the same for the BITS (Background Intelligent Transfer Service) service to set its Startup type to Automatic and Start it.Change Startup Type of BITS to Automatic
    5. Now reboot your PC and check if the update service issue is resolved.
    6. If not, hit the Windows key and open Settings.
    7. Now select Update and Security and in the left pane, head to the Troubleshoot tab.Open Update & Security
    8. Then, in the right pane of the Update & Security window, open Additional Troubleshooters.Open Additional Troubleshooters
    9. Now, in the section of Get Up and Running, expand the option of Windows Update.
    10. Then click on Run the Troubleshooter and let the process complete.Run the Windows Update Troubleshooter
    11. Upon completion, apply the recommended troubleshooting steps and check if the Windows update is working fine.

    Solution 2: Uninstall the Conflicting Applications

    You may encounter the issue at hand if an application on your system is hindering the operation of the update services (especially, the applications that are used to disable automatic Windows updates of a PC). In this case, removing the conflicting applications (StopUpdates10Guard is reported to cause the current issue) may solve the problem.

    1. Perform a clean boot of your system (you can also use Autoruns to find out the problematic application) and check if you can update the Windows of your system. You may have to enable the Windows Update service as discussed in solution 1.
    2. If so, then enable the applications/processes/services one by one (that were disabled during the clean boot process) till you find the application/process/service that was causing the issue.
    3. Once found, either disable the problematic application at the system’s startup or completely uninstall it.

    The StopUpdates10Guard application was reported by some users to create the issue.

    1. Launch the Power User menu (by simultaneously pressing the Windows + X keys) and choose Apps & Features.Open Apps & Features
    2. Now expand the StopUpdates10Guard application and click on the Uninstall button.
    3. Then confirm to uninstall the StopUpdates10Guard utility and let the process complete.
    4. Now reboot your PC and check if the update services issue is resolved.
    5. If you do not want to uninstall StopUpdates10Guard, then you may disable it at the system’s startup.Disable StopUpdates10Guard in the Services tab of the System Configuration

    If StopUpdates10Guard is shown in the Startup tab of the Task Manager but not shown in the Apps list, then you may download and install the StopUpdates10Guard application. Then remove the application through the Apps & Features.

    Solution 3: Update the BIOS and Drivers of Your System to the Latest Builds

    The update services issue may emerge if the BIOS and drivers of your system are outdated or incompatible with the OS modules. In this context, manually updating the BIOS and Drivers of your system may solve the problem.

    1. Manually update the drivers of your PC and BIOS. You may download the latest BIOS/drivers from the OEM website and install them. Also, if your OEM has an update utility (like Dell Support Assist), use that utility to update the drivers/BIOs.
    2. After updating the BIOS/drivers, check if the system is clear of the update services issue.

    Solution 4: Delete the Software Distribution Folder and Manually Update the System

    The update services issue may arise if the Software Distribution folder is corrupt. In this context, deleting the Software Distribution folder and manually updating the system may solve the problem.

    Delete the Software Distribution Folder

    1. Launch the Services manager (as discussed in solution 1) and right-click on the Windows Update service.Stop the Windows Update Service
    2. Now, in the menu shown, select Stop and minimize the Services window (do not close).
    3. Then right-click on the Windows button and choose Run.Open the Run Command From the Quick Access Menu
    4. Now navigate to the following (copy-paste the address):
      \Windows\SoftwareDistribution

      Open Software Distribution Folder

    5. Then delete all the contents of the SoftwareDistribution folder (if you want to play safe, rename the SoftwareDistribution folder) and steer to the Services window.Delete the contents of the Software Distribution Folder
    6. Now right-click on the Windows Update service and choose Start. Start the Windows Update Service
    7. Then check if the system is clear of the update services issue.

    Manually update the System

    1. Launch a web browser and steer to the Windows Catalogue page.
    2. Now, download the latest Windows 10 cumulative update and install it as administrator.Download the Latest Windows Update from the Catalog Website
    3. Then reboot your PC and hopefully, the Windows update is working fine.

    If the issue persists, then performing an in-place upgrade (download the Windows 10 ISO and then launch its setup as administrator) of the Windows of your system may solve the update issue.

      There are a number of requirements to consider when manually configuring devices to comply with updates. They are subject to change with newer versions of the Windows client. The update compliance configuration script will be updated when any configuration requirements change, so you only need to redeploy the script.

      The requirements are divided into different categories:

      1. Verify that the required policies for update compliance are configured correctly.
      2. Devices in each network topology must send data to the required endpoints for update compliance. For example, devices in the main and back office, which may have different network configurations, must be able to access the endpoints.
      3. Make sure you have the necessary Windows 9 services0683 are running or planned. It is recommended that all Microsoft and Windows services be set to their standard defaults to ensure correct functionality.

      Required Policies

      Update Compliance has a number of policies that must be correctly configured for devices to be handled by Microsoft and appear in the Update Compliance section. They are listed below and are separated by whether the policies are configured using mobile device management (MDM) or Group Policy. For both tables:

      • Policy matches the location and name of the policy.
      • Value Specifies what value should be set for the policy. Compliance with updates requires at least basic (or required) diagnostics, but can work with advanced or full (or optional).
      • Function provides information about why a policy is required and what function it performs to comply with updates. In addition, the minimum version required for the policy, if any, will be detailed here.

      Policies Mobile Device Management

      Each MDM policy references its documentation in the CSP hierarchy, providing the exact location in the hierarchy and additional details.

      Policy Data type Meaning Function
      Provider/ ProviderID / CommercialID Line Your business ID Identifies the device as belonging to your organization.
      System/ AllowTelemetry integer 1 — basic Sends basic device information, including quality-related data, application compatibility, and other similar data, to help keep the device secure and up to date. For more information, see Set up Windows diagnostic data for your organization.
      System/ ConfigureTelemetryOptInSettingsUx integer 1. Disable telemetry consent options (in Windows 10 version 1803 and later) controls whether device users can configure diagnostic data to levels lower than the level defined by AllowTelemetry. We recommend disabling this policy, or the actual level of diagnostic data on devices may not be sufficient.
      System/ AllowDeviceNameInDiagnosticData integer 1 — allowed Allows you to send the device name for Windows diagnostic data. If this policy is not configured or set to 0 (disabled), the device name will not be sent and will not appear in the Update Compliance list. #
      System/ AllowUpdateComplianceProcessing integer 16 — allowed Enables data flow through the update compliance data processing system and indicates explicit device registration with the service.
      System/ AllowCommercialDataPipeline integer 1 — included Configures Microsoft as the handler for Windows diagnostic data collected from an Azure Active Directory joined device.

      Group policies

      All group policies that need to be configured to comply with updates are located in Computer Configuration>Policies>Administrative templates >Windows Components\Data collection and preview builds. All of these policies must be in the state «Enabled » and have the value listed below

      Policy Meaning Function
      Customize commercial ID Your business ID Identifies the device as belonging to your organization.
      Enable telemetry 1 — basic Configures the maximum allowable diagnostic data to send to Microsoft. Individual users can still set this value lower than the policy. See the following policy for more information.
      Configuring the telemetry consent user interface 1. Disable diagnostic data consent settings

      (in Windows 10 version 1803 and later) controls whether device users can configure diagnostic data to levels lower than the level defined by AllowTelemetry. We recommend disabling this policy, otherwise the actual level of diagnostic data on devices may not be sufficient.
      Allow device name to be sent to Windows diagnostic data 1 — included Allows you to send the device name for Windows diagnostic data. If this policy is not configured or disabled, the device name will not be sent and will not appear in Update Compliance. #
      Allow update compliance processing 16 — included Enables data flow through the update compliance data processing system and indicates explicit device registration with the service.
      Enable commercial data pipeline 1 — included Configures Microsoft as the handler for Windows diagnostic data collected from an Azure Active Directory joined device.

      Required endpoints

      To allow data sharing between devices, network, and Microsoft Diagnostic Data Service, configure a proxy server to allow devices to communicate with the following endpoints.

      Devices must be able to contact the following endpoints to authenticate and send diagnostic data:

      Endpoint Function
      https://v10c. events.data.microsoft.com User Experience and Diagnostics endpoint for Windows 10 version 1803 and later. DeviceCensus.exe should be run regularly and contact this endpoint to get the most information about update compliance.
      https://v10.vortex-win.data.microsoft.com User Experience and Diagnostics endpoint for Windows 10 version 1709 or earlier.
      https://settings-win.data.microsoft.com Required for the Windows Update client component functionality.
      https://adl.windows.com Required for the Windows Update client component functionality.
      https://watson.telemetry.microsoft.com Windows Error Reporting (Windows Error Reporting), used to provide more sophisticated error reporting when certain component update deployment failures occur.
      https://oca. telemetry.microsoft.com Network failure analysis, used to provide device-specific recommendations and detailed errors when certain failures occur.
      https://login.live.com This endpoint simplifies Microsoft account access and is required to generate the primary ID used for devices. Without this service, devices will not appear in the solution. The Microsoft Account Sign-in Assistant service (wlidsvc) must also be running.

      Required services

      Many Windows and Microsoft services are required to not only enable your device to work, but also to see device data as updated. It is recommended that all default services from the standard interface remain running. The update compliance configuration script checks to see if most of these services are running or allowed to run automatically.

      Install

      1. Orchestrator is starting the installation.
      2. The arbitrator calls the installer to install the package.

      Commit

      1. Orchestrator is restarting.
      2. The arbiter exits before restarting.

      How the update works

      During the update process, the Windows Update Orchestrator client component runs in the background to scan, download, and install updates. It performs these actions automatically according to the settings and automatically so as not to disrupt the use of the computer.

      Scan for updates

      The Windows Update client orchestrator on the computer checks the Microsoft Update server or WSUS endpoint for new updates at random intervals. Random randomization ensures that the Windows Update server client component is not overloaded at the same time as requests. Update Orchestrator only searches for updates added since the last update search, allowing you to find updates quickly and efficiently.

      When checking for updates, the Windows Update Orchestrator client component checks to see if the update is appropriate for your device. It uses the best practices defined by the update publisher, such as Microsoft Office, including corporate group policies.

      Verify that you are familiar with the following terminology that is associated with the Windows Update client component scan:

      Term Definition
      Update We use this term to mean several different things, but in this context it is actually an updated code or change.
      Pack update Update containing 1-N child updates; does not contain useful data.
      Child update Destination update that is bundled with another update; contains useful data.
      Detector update Special update containing only the IsInstalled applicability rule and no payload. Used for preliminary evaluation.
      Category update Special «detectoid» with IsInstalled rule which is always true. Used to group updates and allow the device to filter updates.
      Complete test Scanning with an empty datastore.
      Differential check Scan with previous scan updates already cached in the data store.
      Network test Scanning using the network and checking the update server.
      Offline test A test that does not use the network and a test of the local data store. This is only useful if the network check has been performed before.
      CatScan Category scanning, where the caller can specify category ID to retrieve updates published by that category ID .
      AppCatScan Scanning categories where the caller can specify AppCategoryId to publish apps in this appCategoryId .
      Software synchronization Part of the check that only checks for software updates (both applications and operating system).
      Driver synchronization Part of the check that only checks for driver updates. This synchronization is optional and is performed after software synchronization.
      ProductSync Attribute-based synchronization, in which the client provides a list of device, product, and caller attributes in advance for the service to check for applicability in the cloud.

      How the Windows Update client component

      checks The Windows Update client component does the following when it runs a check.

      Running a check for updates

      When users start scanning the Windows Update client component through the Settings panel, the following occurs:

      Proxy server behavior updates ([MS-WUSP]: simpleAuth Web Service | Microsoft Documentation[ MS-WUSP]: Web Service Client | Microsoft Documentation):

      • An attempt was made to use the system proxy server (set using the netsh command).

      • If the WUA is unable to connect to the service due to a specific proxy, service, or authentication error code, it attempts to use the user’s proxy (typically the user who is logged in).

        Note

        For intranet WSUS Update Service URLs, we provide a Windows Update client component policy setting to select proxy behavior.

      For the Windows Update client component, URLs that are not are used to detect updates, such as downloads or reporting:

      • An attempt was made to use a user proxy.
      • If WUA cannot connect to a service due to a specific proxy, service, or authentication error code, it tries to use the system proxy.
      Service IDs
      • Service IDs indicate which update source is checked.

      • The Windows Update client subsystem treats each service as a separate entity, even though multiple services may contain the same updates.

      • Common Service Identifiers

        Important!

        Here, the ServiceId specifies a client abstraction, not a specific service in the cloud. You should not make assumptions about which server the serviceId will point to. It is entirely driven by responses from the service pointer service.

      Service ServiceId
      Not specified / default Windows Update client component, Microsoft Update, or WSUS
      00000000-0000-0000-0000-000000000000
      Windows Update 9482F4B4-E343-43B6-B170-9A65BC822C77

      Offline Scan Service Using IUpdateServiceManager::AddScanPackageService
      Network troubleshooting

      A common update failure occurs due to network issues. To find the root of the problem, follow these steps:

      • Look for ProtocolTalker messages to view network synchronization traffic between client and server.

      • SOAP errors can be either client-side or server-side. Read message.

      • The Windows Update client component uses the service locator service to discover configurations and endpoints of Microsoft network update sources: Windows Update, Microsoft Update, or Flighting.

        Note

        If you are searching in WSUS or Configuration Manager, you can ignore the warning messages for the service pointer service.

      • Sites that only use WSUS or Configuration Manager may have the service pointer service blocked in the firewall. In this case, the request will fail, and although the service cannot check for the Windows Update or Microsoft Update client component, it can still check for WSUS or Configuration Manager because it is configured locally.

      Downloading updates

      When the Windows Update Orchestrator client component determines which updates apply to your computer, it will begin downloading updates if you have selected the option to download updates automatically. It performs operations in the background without interrupting the normal use of the device.

      To prevent other downloads from being affected or slowed down by downloading updates, the Windows Update client component uses Delivery Optimization, which downloads updates and reduces bandwidth consumption.

      See Configuring Delivery Optimization for Windows 10 updates for more information.

      Install updates

      If the update is applicable, the Arbiter and metadata are downloaded. Depending on the settings of the Windows Update client component, when the download is complete, Arbiter will collect information from the device and compare it with the downloaded metadata to create an «action list».

      The action list describes all the files required from the Windows Update client component and what the installation agent (such as CBS or Setup) should do with them. The list of actions is provided to the installation agent along with the payload to start the installation.

      Fixing updates

      If you configure the automatic updates option, the Windows Update Orchestrator client component automatically restarts the device after updates are installed in most cases. It should restart the device as it may not be safe or fully updated until it restarts. You can use Group Policy, Mobile Device Management (MDM), or the Registry (not recommended) to configure when devices restart after installing a Windows 10 update.

      For more information, see Managing device restarts after an update.

      Essential Services and Connected Windows

      Windows has built-in apps, services, and features to help you do more. Windows also provides additional options for connecting to the Internet. These «connected experiences» can help you in a variety of ways. For example, by allowing the device to track its last known location, you can locate the device if it is lost or stolen.

      When connected, data is sent and processed by Microsoft to provide this connected experience. This data is very important because this information allows us to use cloud connected experiences. This data is called the required service. Required service data may include information related to the operation of the connected connection, which is necessary to secure, obtain, and perform the service as expected. Required service data can also include information that the Connected Experience needs to complete the task, such as Windows configuration information.

      Connected experiences you choose to use in Windows will impact what required service data is sent to us.

      Required service data is also collected and sent to Microsoft for essential services. Core services are used to ensure the security, performance and performance of the product’s work as expected, or are an integral part of the product’s operation. For example, the Windows Update client component is an essential service that ensures you have the latest updates to keep your device secure, up to date, and running. Because these services are important, you won’t be able to disable them.

      The list below describes the main services and connected experiences available in Windows, as well as links to more information about each.

      Note: This article describes the most common core services and connected experiences. To reflect ongoing improvements to these experiences, the list below may be updated periodically.

      Essential Services for Windows

      Description

      Authentication

      You need an authentication service to sign in to your Microsoft account. It verifies your Microsoft identity and gives you access to several apps and features, such as OneDrive and Find My Device. If you can sign in to Windows with your Microsoft account, the authentication service provides Microsoft with a consistent experience across all of your devices.

      Certificates

      Certificates are digital files that are stored on your device and are used to encrypt data and verify the identity of a user or organization.

      • Trusted root certificates are certificates that are issued by a certificate authority (CA) and are stored in the certificate trust list (CTL). Root Certificates Automatic Update service contacts the Windows Update client component to update the CTL. If a new version of the CTL is defined, the list of trusted root certificates stored on your device will be updated.

      Windows Update helps keep your system up-to-date and secure by allowing you to download and install the latest security updates and other updates released by Microsoft. Windows Update determines if updates are applicable to a given computer.

      Microsoft periodically releases updates to users of Windows operating systems and other Microsoft software products. These include updates that improve system reliability and performance, updates that provide new protection against malware and other potentially harmful software, and updates to Windows components. To improve the performance or reliability of hardware components in your system, Microsoft also provides updates to device drivers provided by your computer manufacturer.

      When Windows Update is enabled, software components directly associated with it need to be updated from time to time. This must be done before Windows Update can check for required updates or install other updates. These required updates fix bugs, provide ongoing improvements, and maintain compatibility with Microsoft servers that support Windows Update. When Windows Update is disabled, these updates are not provided.

      When you select the recommended option during installation of the Windows Out Of Box Experience (OOBE) application, Windows Update installs updates automatically. Alternatively, Windows Update can be enabled by selecting one of the following options in the Automatic Updates section of Control Panel.

      • Automatic (recommended).
      • Download updates but let you choose when to install.
      • Notify but do not download or install them automatically.

      After Windows Update is enabled, required updates for Windows Update components will be downloaded and installed automatically without notification. This occurs regardless of the option selected when enabling Windows Update.
