Why is Windows Error Reporting nicknamed “Dr. Watson”?

The nickname for the feature known as Windows Error Reporting is “Dr. Watson”. Where did that name come from?

As you have probably guessed, The name Dr. Watson was inspired by the character of Dr. Watson, the assistant to Sherlock Holmes in the stories by Arthur Conan Doyle.

It is my understanding that the doctor was originally developed as part of Windows 3.0 beta testing. His job was to record data about application crashes to a file, so that the file could be uploaded and included with bug reports. The icon was (and continues to be) a friendly doctor using his stethoscope to investigate a problem.

The Doctor has remained true to the “capture information about an error” aspect of his job. In the meantime, the word “Watson” has expanded its meaning to encompass anonymous end-user feedback mechanisms in general, such as “Content Watson”. (But if you hear “Watson” by itself, the speaker is almost certainly talking about error reporting.)

Raymond has been involved in the evolution of Windows for more than 30 years. In 2003, he began a Web site known as The Old New Thing which has grown in popularity far beyond his wildest imagination, a development which still gives him the heebie-jeebies. The Web site spawned a book, coincidentally also titled The Old New Thing (Addison Wesley 2007). He occasionally appears on the Windows Dev Docs Twitter account to tell stories which convey no useful information.
