Or check the entries under "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths" in the registry.

There's plenty of non MS programs that add themselves there wink To name a few:- Firefox, Nero, Winmerge, Acrord32, Winrar. To run any of these you only need to e.g /run firefox[.exe] [parameters]
Plus of course, anything in a directory in the %path% variable.
