AntiFreeze is an innovative life-saver utility for Windows which helps you in situations where you find your computer locked up.

AntiFreeze is an emergency task manager utility which offers a last recourse when you find your computer in a hung state. Because programs consume too much CPU or too much memory or too many programs have been started, your computer has become unresponsive. The mouse still moves but programs are not responding, you cannot switch to other programs or even close them. You have even tried to start the Windows Task Manager but even that won?t work because it does not get enough attention from the scheduler to respond to your mouse clicks and keyboard presses. You are ready to press the reset button. Instead you can press the hotkey of AntiFreeze. It will put to sleep all running programs except the most critical ones, giving you the opportunity to close down the programs which are causing problems. You may even be able to save or recover your work.

NOTE: press the hotkey in emergency situations only, it is intended an alternative to the reset button, not as an alternative to the Windows Task Manager.
AntiFreeze requires Windows XP Service Pack 2, Windows 2003 Server or Windows Vista (x86 and x64 editions).
