We are discussing at techsupportalert what to suggest for beginner/average/advanced user. I'd definitely like to add LUA (and perhaps UAC+TweakUAC) to VISTA. I have seen no problems at all when using them. I was opposed eg. due to the following problem (UAC): "If you run an unsigned EXE it throws a warning message, agreeing to run it doesn't get recorded anywhere so the next time you run the program you get the same thing. Sure I can hack around this but why should I have to? I would think it extremely unlikely that I am the only person running unsigned programs. Indeed, most freeware is unsigned due to the cost of buying a digital certificate." What do you people think? Is this a common problem? Have you found LUA/UAC (un)comfortable to use?
