"This PC" folder pops up constantly in Windows 8.1

[Chrssy]

I have a problem where the "this PC" folder pops up constantly, even while typing this. I have windows 8.1 and yes, I have disabled the swipe gesture thing. I found it mostly occurs while typing.

Physically clean your keyboard. Win+E is the keyboard shortcut that opens Explorer.

Boot in Clean Boot state and see if issue occurs. If it does not, then it means some process is causing this to happen. Try to isolate it.

Computer or Documents Folder opens automatically at Start
Windows Libraries folder keeps opening or popping up at startup.
