on a side note, UAC isn't as efficient, in terms of security in Windows, as the "root" barrier in Linux. It's been demonstrated and acknowledged by many, including MS themselves. They of course didn't refer to Linux (yeah it's their policy to never mention it
), but said that it was very easy for malware to bypass UAC and gain admin privilege. UAC was just meant to encourage software programmers to make their apps run with standard non-elevated rights. Sorry can't find the link to the article anymore...so basically, an MS rep was saying that UAC didn't really make Windows more secure.
