The only time I ever see anything result from clicking the "Send Error Report" button is when Windows itself goes ker-splat ("explorer.exe has encountered a problem and needs to close. We want you to believe that we're actually sorry for the inconvenience..." etc. etc.). I get this on my laptop once in a blue moon, usually when Adobe Reader or one of my antivirus/anti-spam programs decides to suddenly update itself while I'm playing one of my racing simulators. Shortly after clicking the button Internet Explorer will start itself and take me to a Microsoft website that basically explains what I already knew, that two resource-consuming programs tried to run at the same time, one interrupted the other, and Windows fell flat on its face.
