Well this is probably for another thread, but I have been around computers since the 80's too and I don't recommend turning UAC off. Sure, you and I might know what we are doing, but does everyone? 

Microsoft is not telling you what todbo or what not to do, windows it's telling you what the system is trying to do and asking for a confirmation. This stops a lot of malware and virus.

So, if you know excactly what UAC is doing and you can do it on your own and can do a better job, you can safely turn it off. If you have no idea, or know only a little bit about what it's for, leave it on.

I don't use an antivirus and I don't use a firewall, but that doesn't mean nobody should, in fact, people are far safer using them than not.

That's my personal opinion, and there's many opisite views out there.
