Windows 10: I need help with windows taskbar only partially functioning - programs won't open

So I open any program or document - no problem.Open multiple programs and documents - no problem.Taskbar shows correctly which programs or documents are open.But I cannot switch between documents - when I click on the taskbar icon for whichever program I am trying to open, the open windows in each program may or may not flicker, and when I click on them, they won't open, so I have to minimise each open window, until I find the one I was trying to open. However, once they are minimised, I can't get them back, and I have to right-click, select 'close all windows' and open the program and documen

Windows won`t open an program when using Microsoft user

Windows won`t open an program when I try to open it with Microsoft account user, but when I login with local account, that program opens. I have tried with 2 Microsoft accounts, 1 admin and 1 normal user, and it won`t open in either one of them. What can cause this?

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!
