This has been raised before but I can't find the post/thread.
This is the Error Reported when trying to run the wuauclt.exe on a Win 7 client. Yet the the command executes perfectly locally. I don't know but I doubt the problem is confined to this one executable.
C:\Windows\system32>wuauclt.exe /detectnow /updatenow 'wuauclt.exe' is not recognized as an internal or external command, operable program or batch file.
