[OS] Error Messages of Windows

The Esteemed First Blogger, rocket scientist and Campbell and Promethius awards winner, Dr. Jerry Pournelle, stumbled across a nice bit of shareware while looking into external USB HD backup system failures: Error Messages for Windows.

The author describes it as:

a small utility that will allow you to look up MS Windows error code numbers and display a descriptive message explaining what the numeric code actually means. If you have software programs that produce numeric error codes now you can find out what they really mean.

Not shabby.
