Go to Settings > Update & Security > Troubleshoot > Other troubleshooters.
Find and run the Windows Update troubleshooter and follow its instructions.
2. Check Your Internet Connection
Ensure you have a stable internet connection, as updates require download access.
3.Check for Disk Space
Ensure you have enough disk space, as insufficient space can prevent updates from installing. Go to Settings > System > Storage to see available space.
4.Install the Update Manually
Go to the Microsoft Update Catalog website.
Download and install the update manually
When I run the troubleshooter, I just get "The Windows Update diagnostic failed to run I'm sorry. I was unable to run the Windows Update diagnostic.". I've never in my life got any solution out of the MS-provided "troubleshooters".
