An app that does nothing

Dud is a program that does absolutely nothing. Run it and it will immediately unload. It can be used as a replacement for annoying system files, such as helpctr.exe or stobject.dll. Simply replace the file with dud.exe, and you'll never see the offending app again.

The zipped package is 1kb. Dud.exe itself is merely 3kb, using 60kb of memory.
