Windows 11 26200.9278

Hi, good day!

Microsoft has begun implementing and releasing Optional preview updates that are typically released on the 3rd or 4th week of every month. These updates allow admins to test the patch before its mandatory launch on Patch Tuesday (2nd week of the month). If you are not experiencing any issues with your system, there is no need to install the KB5120998 preview update.

I recommend reporting the issue via Feedback Hub app to notify Microsoft.

Please try to uninstall the recent KB5120998 preview update.

If this fixes the issue, please try to temporarily pause updates to prevent it from reinstalling.

Open Settings > Windows Update > Pause updates > Pause for 1 week

To prevent optional preview updates from appearing and installing in the future, press Start > Settings > Windows Update. Toggle off "Get the latest updates as soon as they're available" option. Restart your computer.

I look forward to receiving your update and I'm willing to collaborate with you till we resolve the issue. Do keep me informed by clicking "Add comment" below.
