How to shut down a process which can not be turned off from Windows task manager?

It is easy. You can use dedicated software such as IceSword to shut down a process. However, Windows already provides us with the tools that can shut down almost all the processes.

c:>ntsd -c q -p PID

Except System, SMSS.EXE, CSRSS.EXE, ntsd can kill most of other processes. You only need to change the ‘PID’ to the ID of the process that you would like to turn off. If you don’t know the ID of a process, go to Windows task manger -> Processes tab, select View -> Select Columns and then check the PID option. Now you can view the ID of all the processes.

Windows XP also provides users with two useful commands: tasklist and tskill. Tasklist, as the name, can list all the processes and their information. Tskill can kill the processes. It is simple to use: tskill [program name]!
