Kill All Running Apps .BAT – Repair Tool of the Week | Technibble Quote:

This .BAT file will kill all currently running apps on a system that the user started with the exception of a few locked Windows processes and some antivirus products. This comes in handy when you are working on a system that has too many processes running and thus slowing it down; often to the point where its difficult to do any work on it.
Being a BAT file, this script is obviously highly customizable. It works on a “if the process is not in this list, then kill it” system; so you can add processes to the list that you do not to be killed such as the menu for your USB drive applications or Firefox.
