Windows 7: CTRL+backspace started minimizing windows instead of deleting words

Quite a strange problem. Out of nowhere, CTRL+backspace has started minimizing windows instead of backspacing the last word in a text box. This is very annoying, since I'm used to using this shortcut to fix mistakes or wiping small chunks of text. Even while writing this, I've minimized the browser window a few times, I use this shortcut that much!

I'm savvy with computers, so feel free to use advanced terminology with me.

Thanks!



EDIT: Problem was caused by "GameCompanion", a tool for making games run in borderless windows. Adds itself to your Windows startup. To solve, open msconfig and untick GameCompanion in the Startup tab.

AutoHotkey

More of a workaround, but I'll use it if there's no native way to solve it.

How strange. I've also noticed another shortcut giving a weird result. Pressing CTRL+ALT makes the word "DEFAULT" display in big letters on my main monitor. Here's a print screen.

Note that I haven't installed any new software that could have caused this problem.

Thanks a lot for the offer, but I don't think it would really help. I've already had a good look around at what could be causing it, and nothing at all. AutoHotKey won't help either, since it cannot change a keyboard shortcut, it can at most add one on top. I was just hoping there would be someone who would see this thread and immediately recognize the problem :P

Do you have a spare keyboard around you can try out to see if it has the same problem? Has anything happened to the keyboard, say something spilling on it for example?

I'll be blunt with you. I've got sensitive data on this computer, and even just opening those ports is a serious security risk.

Just tried this. Didn't help, it seems to be a software issue. I reinstalled the keyboard drivers as well. No dice.

Okay fair enough.

What is the make and model of the keyboard?

For completeness, it's a Logitech Illuminated Keyboard.

But regarding the main topic, the problem seems to have gone away on its own. I haven't uninstalled, installed, or modified ANYTHING. After restarting yet again, the problem was still there, and just now I was writing a document and used the keyboard shortcut, just to see it work properly! The DEFAULT thing when pressing CTRL+ALT has also vanished... damn it Windows! Why must you toy with users like this?

Thanks for all the help, though. Windows truly is unpredictable.

You may have the best of intentions, but it is extremely ill advised for anyone to allow any unknown person or entity to have remote access to a computer. The only knowledge I have about you is a post in a newsgroup, so, you may be some startup hacker looking for easy access to a computer while learning the ropes. On the other hand, you may be a top computer expert in the field of security, but I would not suggest anyone find out "which one" by allowing you remote access to their computer; additionally, I seriously doubt a security expert would even suggest allowing remote access to a stranger.

Just my .02 cents.
