Dr. Watson is a Windows utility which runs in the background and keeps checking your computer for errors and problems. When Dr.Watson detects a problem or error with any application in your computer it immediately throws an alert and informs you that the program has encountered an error and will be shut down. You will also be given the option of sending the error to Microsoft. Though this can be really a pain at times, think about it – it’s a whole lot better to restart one single application in your computer, than to restart the whole computer!
When Dr.Watson encounters a problem in your computer, it not only displays an error message/alert, but also creates a log of the error. The Dr.Watson log file can is located at C:\Documents and Settings\All Users\Application Data\Microsoft\DrWatson and is called drwtsn32.log. You can find the latest error message if you scroll down to the very bottom of the file.
Generally, you don’t have to be too concerned when you see one of these error message flash on your screen because it usually goes away when you restart your computer. But if you are getting repeated error messages about an application, then you will have to look into it more closely.
