Windows 10: My Windows won't activate anymore

Hello,my Windows is no longer activated for some reason. So, I build my new PC and bought the license via Microsoft Store. I did receive the order confirmation. Although there is no key in the email, my Windows was activated the next day. I can personalize the setting, etc. So, I wasn't thinking too much into it. However, after a couple hours later, my Windows is not activated anymore. On order detail, the page doesn't even exist.I tried troubleshoot the issue: Setting -> System -> Troubleshoot -> I changed hardware on this device recently recommended by the internet. Nothing works.

Windows 10 won´t start any program as Administrator

Hello. I´m having this issue since installed one of the latest Windows 10 system updates.

When I try to open any program that requires Administrator confirmation (that screen with the Yes/No question), this dialog won´t appear anymore. The screen background stays darkened and nothing happens.

1. Using Windows 10 Home (x64)
2. My microsoft user account is properly checked
3. I´m the administrator of the PC
4. Already tried do create another administrator user account - same problem, no success
5. Cannot start any program/service that requires administrator authorization (not even regedit)

Please help!
