Why the Windows Update force to reboot the Windows 11 PC

Question

I am facing a incident. one user reported the Windows Update message to force to reboot the Desktop PC after installed the security patch (KB5046633).

After investigation, the finding is as below:

1. The Desktop PC is getting Windows Patch from WSUS server.
2. No received other user reported same problem. (however that only this PC is Windows 11 in the group of WSUS, other is Windows 10. Other Windows 11 in other group is normal.)
3. In general, we added the "NoAutoRebootWithLoggedOnUsers" to prevent to affect users.
4. Double checked the "NoAutoRebootWithLoggedOnUsers" is set to "1" in Registry.
5. The PC is assign the same OU group in AD with other PCs.
6. This is no problem last month.

The configuration is applied nearly half year, I am no idea what factor caused this issue.

Now, I have try to clone the same Windows image to new device and apply same AD & WSUS group for simulate issue.

Any expert can advise any factor will cause this issue?

Attached information for help. Thanks

Hello

Thank you for posting in Q&A forum.

Here are some steps you can take to address this issue:

1. Check Windows Update Settings:

• Ensure that the active hours are set correctly to prevent reboots during working hours. Go to Settings > Update & Security > Windows Update > Change active hours.

2. Run Windows Update Troubleshooter:

• Open Settings > Update & Security > Troubleshoot > Additional troubleshooters.

• Select Windows Update and run the troubleshooter to detect and fix any issues.

3. Reset Windows Update Components:

• Open Command Prompt as an administrator and run the following commands:

net stop wuauserv

net stop cryptSvc

net stop bits

net stop msiserver

Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

Ren C:\Windows\System32\catroot2 Catroot2.old

net start wuauserv

net start cryptSvc

net start bits

net start msiserver

• Restart the computer and check if the issue persists.

4. Check for Pending Updates:

• Sometimes, other pending updates can cause repeated reboot prompts. Ensure all updates are installed. Go to Settings > Update & Security > Windows Update and check for updates.

5. Review Event Logs:

• Open Event Viewer and navigate to Windows Logs > System. Look for any errors or warnings related to Windows Update or the specific KB5046633 patch.

3. Pause Updates Temporarily:

• As a temporary measure, you can pause updates to prevent further disruptions. Go to Settings > Update & Security > Windows Update > Pause updates for 7 days.
