For test purposes, we have created some Windows update rings and assign them to test Windows 10 machines. The user experience settings are set as below:

Automatic update behavior: Auto install and restart at maintenance time

Active hours start: 6 AM

Active hours start: 10 PM

However, some users are still reported that Windows updates force a reboot during the active hours. It may interrupt the user's work. How to troubleshoot the issue and ensure the devices won't restart during active hours?

    Hello @taya taya !

    I understand that your Test Update settings are causing some restarts on Active Hours which is not desired

    For such a problem you may need to check these :

    • Ensure that the machines have installed all the available updates. In some cases, pending updates might be causing the reboots. Manually check for updates and verify that there are no pending installations.
    • Are there any failed or partially installed updates that might trigger a reboot ? If there are failed updates, try to install them manually or troubleshoot the specific update errors.
    • (SOS) If your organization utilizes Group Policy for managing Windows updates, review the relevant policies that control the update behavior. Ensure that the policies are correctly configured and not conflicting with the desired Active Hours settings. Adjust the policies if necessary to align with the intended behavior.
    • Check the Windows Event Viewer logs for any relevant events related to Windows Update or system reboots.
    • Utilize the built-in Windows Update Troubleshooter to automatically detect and resolve common issues related to Windows updates. Run the troubleshooter on the affected machines and follow any recommended actions it suggests.

    Also read the Docs!

    If SCCM is also used (Co Management) check SCCM settings for possibility of overrides!

    Hi,

    Thank you for posting in Microsoft Q&A forum.

    1,We can check the registry key under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PolicyManager\current\device\Update to ensure all the Windows Update Ring policies are successfully deployed by Intune to the target device, here is a link with details for the reference:

    https://techcommunity.microsoft.com/t5/intune-customer-success/support-tip-troubleshooting-windows-10-update-ring-policies/ba-p/714046

    2,Meanwhile, please check if we set the deadline settings in Windows update rings. If yes, before the deadline, restarts can be scheduled by users or automatically scheduled outside of active hours, according to Update/ConfigureDeadlineNoAutoReboot. After deadline passes, restarts will occur regardless of active hours and users won't be able to reschedule.

    https://learn.microsoft.com/en-us/windows/client-management/mdm/policy-csp-update#update-configuredeadlineforqualityupdates

    We can check if the deadline is passed which cause the restart occurs in Active hour.

    Hope the above information can help. Have a nice day!

    Best regards,

    Simon
