Windows 10: System volume won't stay off

I keep muting the system sound notifications and the volume keeps going back to 100%. This is not happening on one computer, it is happening on 2 different computers, so I am guessing it is a Windows 11 issue. How to I keep the system volume at 0%,

Volume Mute Light won´t change color

I have an HP ProBook 6440b with a Win 10 Pro os. My problem is the volume mute light (#5 in the service manual, page 2-6). The switch works o.k. and shows when the mute function is on or off on the desktop but the light stays orange (muted position) regardless of the function being on or off. I know that the blue color is there as I see it flicker so slightly during upbooting but I can´t find out how to have the blue color show when the speakers are not muted. The wireless button (#4; page 2-6) changes color and the function works properly when pushed (tried it as a function comparison test) so I think this may be a slight software glitch in the sound system code but how to find and fix is way beyond my knowledge and skills. If anyone knows how to fix this problem, please do tell but baby steps please as my computer skills are truly limited (old dog, new trick syndrome rules here).

 

Volume Mute Light won´t change color

Before I follow your suggestions, a quick update: as the updating didn´t seem to work I stopped trying and just left it alone for awhile. About a half hour later I looked over and saw that the mute light was now blue. I tried the button but it and the volume buttons did not work at all. On the screen I was told that I needed to reboot, which I did and now the system has returned back to the way it was before: everything works except that the mute light does not change to blue as it should when the speakers are not muted. WTF?

 

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!
