Dr. Watson overview
Dr. Watson for Windows is a program error debugger
The information obtained and logged by Dr. Watson is the information needed by technical support groups to diagnose a program error for a computer running Windows. A text file (Drwtsn32.log) is created whenever an error is detected, and can be delivered to support personnel by the method they prefer. You also have the option of creating a crash dump file, which is a binary file that a programmer can load into a debugger.
If a program error occurs, Dr. Watson will start automatically. To start Dr. Watson, click Start, click Run, and then type drwtsn32. To start Dr. Watson from a command prompt, change to the root directory, and then type drwtsn32.
