For goodness' sake, you haven't even tried it yet!

Don't, whatever you do, let this newsgroup influence important security
decisions. The people here are NOT representative of the whole user base.
Most are here because they have a problem, or because they like solving
problems. Hence all you get to hear about are problems.

Remember, UAC is there for a reason, and if you turn it off it has a number
of other subtle side effects, such as removing the IE7 extra-secure sandbox.

UAC prompts are fairly rare once you've finished installing all your
software and messing about getting everything set up correctly. Software
which isn't properly Vista compatible causes more prompts, so I suggest you
avoid it.

Speaking for myself, I'm rather glad that UAC warns me when something with
security implications is about to happen. In that respect it's just the
same as the elevation prompts in Linux and Mac OSX.

Please consider my advice: take at least a week, and preferably two, before
deciding whether to disable UAC.

If you are still tempted, consider this as a good alternative: make your
account an Administrator, and set your UAC such that it only requires you to
click the button, not to enter your password. The security advantages are
virtually identical if you are the sole user of the PC, and it honestly is
no bother at all to click the button.
