How to stop application that freezed and locked task manager?

I had been playing a game and it stuck. So I press Ctrl-Alt-Del and menu appears. I select task manager and it opens, but, since my frozen application is fullscreen, the task manager is below it, so I get no access to task manager window.
No amount of pressing Alt-Tab, Alt-F4, Alt-Enter, Alt+mouse drag did help. I ended up pressing reset.
What was I supposed to do?

Try telling the Task Manager to always be on top.

1. Open up the Task Manager before you start your application/game.
2. Click "Options" ("Možnosti" in the picture below)
3. Check "Always on top" ("Vždy navrchu" in the picture below)

Next time you should be able to view it. Also try Alt-Tab-ing out of the app/game, so the focus is on something different.

I tested it on Windows 8 on Wolfenstein: Enemy Territory, which is a game you need a special program to minimise :D .

(my Windows is in Slovak)

This will terminate all non-responsive programs and allow you to resume normal functionality:

taskkill /f /fi "status eq not responding"

You can run it from command prompt or start menu.
