When a program abnormally terminates, Windows XP offers to send an error report to Microsoft.
You can control this behavior via the registry:
1. Use the Registry Editor to Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PCHealth\ErrorReporting.
2. Edit the DoReport Value Name, a REG_DWORD data type, and set the data value to 0 to disable sending. A data value of 1, the default, enables sending.
