Yesterday two new developers came into my office and wanted to know what some weird Win32 error code mapped to.  I tried to get them to turn their heads as I looked it up because I didn't want them to know how easy this was. 

I just used err.exe, which lets you specify a Win32 error on the command prompt and returns what the error code is.  It's available at:

Unfortunately now no one will be impressed when I can tell them their hard to find error code is in the future :(.
