Check Windows help for 'Dr Watson'; this is a diagnostic utility in Windows 9x, and I am pretty sure it is in XP as well. I have a similar utility from something else, so have not used Dr Watson.
From Windows 98 Help;
Dr. Watson is a diagnostic tool that takes a snapshot of your system whenever a system fault occurs. It intercepts software faults, identifies the software that faulted, and offers a detailed description of the cause. Dr. Watson can often diagnose the issue and offer a suggested course of action. When you contact Microsoft Technical Support for assistance, Dr. Watson is the tool used to help evaluate the problem.
