Examples: Every time I type "B", Windows Media Player opens. "Control" now switches tabs instantly for some reason. Copy-pasting text? Good luck with a non-functional control key.

I heard it could have something to do with the Windows key being stuck, but no other keys appear to be affected (Win+L should lock my computer, which would lock me out permanently because I can't type passwords like this). Sticky keys is NOT enabled.

This issue had happened before, but then it was much much worse, with almost all keys doing something I never asked them to do. The problem stopped by itself, also without an obvious cause.

This started without warning or reason. I never shut my computer down, so it can't have happened during sleep.

Any ideas?

PS: just a few hours ago, the problem disappeared. I went to a meeting for about two hours, and when I returned the problem was back... :banghead:

Keyboard could be failing. If you have a spare, try it for a while.

You didn't say, is this a laptop or a desktop? It does sound like a key is stuck.
If a desktop, turn the keyboard upside down give it a couple of shakes and and blow out the keys with a can of compressed air to remove any particles, dust or food crumbs.
Try using the onscreen keyboard, does the same thing happen? If not, then it is not a software issue, try using a different USB keyboard.

It's a desktop keyboard. I did spill coke on it a few months ago. I removed all the keys, rinsed it with water and put it in the oven at 70°C (158°F) for a few hours until it was dry.

I'm buying a new keyboard today. I'll update this post when I have results.

That's the kind of info we need up front. You obviously needed a new one. Coke can be a vile substance.

:nono: :facepalm:
As said, that would have been good to know, you need a new one, keyboards are cheap, there is no reason to try and fix it

Got the new keyboard. No problems so far, though to be honest the problem had disappeared again before I started using it. Fingers crossed it stays gone this time.
