Hello, thank you for reaching out to Microsoft Q&A.
May I please know the version of Windows 11 installed on your computer?
Type 'Winver' in the search bar on the taskbar and click Enter.
Post a screenshot of the resulting dialog box.
Do you get any error codes or messages in the Windows Update Settings?
Have you tried running the Windows Update Troubleshooter at least?
If not, go to Start > Settings > System > Troubleshoot> Other troubleshooters.
Locate Windows Update in the list, and click Run.
Once the troubleshooter is finished running, restart your computer and check for Windows Updates again.
