Seems like Microsoft has some useful support site live. Unfortunately this site requires the use of a .NET passport and the error reporting services running... Anyway this might be useful for some of our readers. Microsoft is committed to making Windows the most reliable operating system available. New and enhanced features contribute to increased reliability, and additional resources, including Windows Online Crash Analysis, provide information to help you optimize your system. Read more... How it works If you experience a blue screen crash event, or Stop error, while using Microsoft Windows XP, you can upload the error report to our site for analysis. What to expect Microsoft actively analyzes all error reports and prioritizes them based on the number of customers affected by the Stop error covered in the error report. We will try to determine the cause of the Stop error you submit, categorize it according to the type of issue encountered, and send you the initial results by e-mail within 24 hours. You can check the status of your error report at any time. However, because error reports do not always contain enough information to positively identify the source of the issue, we might need to collect a number of similar error reports from other customers before a pattern is discovered, or follow up with you further to gather additional information. Furthermore, some error reports might require additional resources (such as a hardware debugger or a live debugger session) before a solution can be found. Although we might not be able to provide a solution for your particular Stop error, all information submitted is used to further improve the quality and reliability of Windows.
