Hello,
Make sure your WSUS server version is up to date. Older versions of WSUS may not support the latest operating system updates, such as Windows 11.
Check the synchronization settings in the WSUS console to ensure that the correct category and product are selected. For Windows 11, you will need to make sure that Windows 11 is selected in Products and that the relevant update type is selected in Categories, such as Critical Updates. For example, “Critical Updates”, “Security Updates”, and so on.
Manually start a synchronization operation to ensure that the WSUS server gets the latest list of updates.
Review the WSUS server's log files for any possible error messages or warnings that may help diagnose why it is unable to synchronize Windows 11 updates.
Best Regards,
Hania Lian
