More often than not, the simplest solution is the best solution (think: Occam’s razor).

So, when your computer “randomly” starts translating every press of the keyboard into WinKey+[key] don’t:

• …assume StickyKeys is on, even though the check box in Accessibility options is clearly unchecked
• …suspect the latest driver update
• …blame Logitech/Microsoft/[insert-keyboard-manufacturer-here] for making such a shitty piece of hardware
• …assume Windows “just needs to be rebooted like it always does”
• …suspect Chinese hackers

Instead, have you non-computer oriented friend come over. Have him look under your desk and declare that it’d be pretty funny if that keyboard on the floor with a book on top of it was plugged in and causing all the problems. Chuckle at your friend…then awkwardly realize that said keyboard is plugged in.
