KillWOW is a simple little utility which terminates one or more WOW (Windows on Windows) subsystems on Window NT. The syntax is simple. KillWOW with no parameters will show a numbered list of WOW systems, and the tasks running in them. Give the numbers of the ones to kill, and they will be terminated. "KillWOW *" terminates all running WOW subsystem. This application is released into the public domain, and I promise nothing to anyone about its usability, reliability or anything else. Use it at your own risk.
