UAC will not elevate

Question

This issue is happening on all Windows 10 systems 1909 and 20H2. I have tried DISM repairs, new profiles, a fresh image, a fresh image with no group policy. It will work for about an hour after each reboot, but then it starts to fail again.

Users operate under standard domain user accounts.

When I try to elevate a program using UAC it fails.

The UAC prompt box will appear, take my username and password, and then the screen stays as a muted darkened version of my blank wallpaper.

The PC will sit like this for a 2 minutes and then go back to the desktop without the elevated permission ever happening.

If I press Ctrl-Alt-Del and just cancel out of the task manager I can get the desktop to operate again but the permission elevation dose not happen.

Similarly, I cannot seem to do "Switch User" after an hour as well, the will spin until I have to hard reboot.

And my Group Policies will stop applying and I'll receive an "Access Denied" unless i reboot as well.

Hi, my name is Anderson Souza, I hope I can help you with your issue.

I believe that your question will be better resolved if it is posted in a more suitable location such as the new Microsoft Q&A forum that is replacing the old TechNet. As it is a question aimed at infrastructure administrators that have more knowledge about the Microsoft enterprise technologies like an Active Directory environment and the use of GPO, I believe that you will get better results there, since this forum here is intended for home Windows users.
