I'm having some problems with my kebyoard layout. I'm running plain Windows 7 on a Dell Latitute E6530 computer. The ctrl, alt and windows keys are mixed up.
CTRL key responds as usual
Windows key responds as ALT. Nothing else responds as Windows key
ALT key responds as CTRL
I think the problem appeared after a Windows update.
I've tried uninstalling the keyboard drivers, tested external keyboard, changed language, etc, but nothing has fixed the problem.
