If a program or process is not responding (hangs) while waiting for user input, and cannot accept input or be terminated, usually the only way to terminate the process is to restart the computer.


If you cannot restart the computer to terminate the process that is not responding, use the Kill.exe program from the Windows Resource Kit to terminate the process for the program that is not responding. When you use Kill.exe, you do not have to restart the computer.

Use the process button of Task Manager in Windows to identify the process ID (PID) of the program that is not responding. In Windows NT 3.51, use Pviewer.exe or Tlist.exe to identify the process ID. If the process was started with AT Scheduler, use AT to schedule the kill command and terminate the process that is not responding.

For example:

AT 10:30:40 C:<resource kit root>\kill -f 175

NOTE: In many cases the process name will work if it is unique. This will terminate the program with Process ID of 175.
