Remote desktop pressing Windows key randomly
Windows 7 Keyboard shortcuts switch unexpectedly
Periodically, I hit some secret keyboard shortcut that causes windows to enter a super-duper shortcut mode where pressing e opens explorer, and nearly everything else does too. It's a bit like Windows-key lock mode. The only way to fix it is to restart the computer.
What is this mode, how did I get into it, and how do I get out of it?
Sounds like your Windows key got stuck. Try giving it a few firm taps, that normally releases it.
