End Task In Windows XP Automatically
Windows waits too long before killing a non-responsive task?
To remedy this, you can start automatic handling of end tasks. Wherein, the tasks will be implicitly terminated on a certain interval
Procedure -
1. In the Registry Editor , go to HKEY_CURRENT_USER\Control\Panel\Desktop\, change the value of “AutoEndTasks” key to “1“.
2. Change the “WaitToKillAppTimeout” key’s value to the number you want. The default is 20000 ms. This is the interval as the name specifies.
