To disable the error report window (that pops up if a task crashed with the options to close program or send report to ms)
you have to edit the registry.

Locate the key:



Code:
HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet001 \ Control \ Windows \ ErrorMode
the default value is "0". Change it to "2" (without " )

then locate
Code:
HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ Windows Error Reporting \ DontShowUI
the default value is "0". Change it to "1" (without " )

This is tested with Windows 2008 Server Edition. Should work with Vista/Win7 as well.
