I have a number of Windows 11 workstations in my PM, and they still show the OS as Windows 10. Is this a PM issue or WSUS? PM version is 2024.2 and WSUS is 10.0.17763.5830.
This is, unfortunately, a Windows issue for which I don't believe there is any current fix. In the Registry of a Windows 11 machine it still shows as Windows 10.
If you go to this registry key on a Windows 11 device, you will see that it still shows Windows 10. - Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
This is what WSUS is looking at for the version I believe
