Almost every Microsoft Windows user will have seen the Windows error reporting dialog box at some point in time, usually when an application has crashed and has to be temrinated in an un-expected manner.
The premise of the the error report is that Microsoft will gather information about the crash to try and improve Windows and provide a solution to the person who submitted the report. In truth, very few people receive any news from Microsoft and the error reporting is nothing more than an annoyance.
With a little work it's possible to disable the error reporting feature so that you won't be plagued by the dialog boxes again.
