It's a Windows XP error report. Turn it off (permanently)

To do this:

Go to "Control Panel", Then "System"
Click on "Advanced"

Click on "Error Reporting" and change to "Disable Error Reporting"

You won't get this on any site again, I usually uncheck the "But notify when critical errors occur" also.

While you are here, untick the box in "Advanced" that says "Automatically reboot"

Hope this helps, I have had no trouble doing this on ANY system
