AntiFreeze offers a last recourse when you find your computer in a hung state. Antifreeze has been retracted. Its functionality is replaced by WhySoSlow.

Sometimes it may help waiting until the storm is over. But if after several minutes you are still waiting, and you are an experienced user you are likely to press the key combination ALT+CTRL+DELETE which allows you to fire up the task manager to see which programs are taking up all the CPU time and systems resources. At this point, you may be able to recover the system and get it in a responsive state again by terminating the offending processes. If this works, then all fine. But very often the system is so busy that even the task manager will not help you. It just does not get enough processor attention to be able to handle your clicks or key presses. Then you are very likely to give up and press the reset button on your machine for a reboot.

This is where AntiFreeze offers a solution. AntiFreeze is a utility with a very small footprint, sitting in your tray, waiting for you to press the hotkey combination (ALT+CTRL+WIN+HOME by default). You should use it only in emergency situations, consider it an alternative for the reset button.
