I recently stumbled upon a problem.
I can’t use certain settings on Windows such as right-clicking in my desktop and clicking the "Personalize" option. Whenever I click on it, the command prompt appears for a brief second. Sometimes it opens up and closes immediately but sometimes it stays there for a second giving me an error message saying: ERROR: ACCESS DENIED.
Also right-clicking on my taskbar and clicking the "Settings for the taskbar" option. Whenever I click on it, the same error appears.
The same thing goes for when I try opening my sound settings by right-clicking on the speaker icon in the bottom right corner. When I right-click on the speaker icon and select the "Open sound settings" option, the command prompt opens up and behaves the same way.
I need help!
