My Windows 11 Home (24H2) is behaving as if Windows Update is totally non-existent as of a day ago. Whenever I click "Check for updates" from the Start menu, it takes me to the default Settings screen. Whenever I click on the Windows Update panel in the top-right of that screen, nothing happens. I appear to no longer have any way of actually navigating to and running Windows update.
Things I've tried:
DISM /Online /Cleanup-Image /RestoreHealthSFC /ScanNow- Starting/restarting all Windows services I believe to be behind Windows Update
I only have one inclination of what happened to begin causing that, and it may be because I followed these instructions: https://beebom.com/how-enable-windows-sandbox-windows-11/
Those instructions did not work, by the way—Windows Sandbox won't launch, so I've since turned that optional feature off.
The last time I ran a System Restore, it resulted in corrupted data and other issues, so I don't even want to chance it. Any ideas?
