See http://stackoverflow.com/questions/304319/is-there-an-equivalent-of-which-on..., where.exe does it on windows, where /? gives help for it, and for example

C:\Users\vilvouti>where notepad.exe C:\Windows\System32\notepad.exe C:\Windows\notepad.exe

So just run 'where' for it and pick the first line if successful, I guess.

Unfortunately, "where.exe" was only shipped starting with Windows 2003 Server, so it doesn't exist on the stock Windows XP installation that is presumably still the Armed Bear MSFT lowest common denominator.

But thanks for the link, as I couldn't easily find such an authoritative answer in my searching.
