|I didn't figure out it was UAC, cause it is a Vista in another language than english ;)|
Anyway, wan't it the case that in XP and so, this kind of thing was working, were you could allow, or not allow, any given executable name to be run ?
It's a bit worrying, that 20 years of Windows cannot provide a better solution, but there you go, it's still Windows, an unsafe OS it any way, so why bother ?
Method #2 in http://www.petri.co.il/disable_uac_... is funny : still people are being told to use REGEDIT ... it's like giving a knif to a murderer ! Here, do something with it.
Windows, gotta love it.
