You may be one of the easy going people who doesn't mind the UAC being turned on in Vista and nagging you when you're trying to do most anything on your machine.  All the power to you and you must be a saint.  I, however, immediately turn off UAC because it annoys the hell out of me.  But now Windows 7 beta has the new feature for selecting the nag level of UAC.

After a few days of running Win 7, I've had UAC set to the lowest setting and only a couple of UAC messages have popped up.  I believe that I may be able to live with this setting.  I understand the idea behind UAC and there certainly is some usefulness for the feature.  So for now, I will try using Win 7 with UAC actually turned on and see how it works.  So far, so good.
