Change the Timeout for Hanged Applications
How can I change the timeout for hanged applications in Windows XP?
When an application hangs and no longer responds, Windows XP displays a dialog box that prompts you to kill the application or wait a while longer.
By default, the dialog box appears after the application hasn’t responded for a half of a second. You can tweak XP to increase or decrease the amount of time it takes before XP reports that the program has hung.
To do so do the following:
Start Registry Editor (Regedit.exe).
Locate the following key in the registry:
Make sure you backup the keys by exporting them to a .reg file.
On the HungAppTimeout value, change the setting from 5000 (the default) to any time you want (in milliseconds – decimal).
Close the registry editor.
Restart your computer.
