UAC dormant if there is only one user, and then later, add the UAC if another user is added to the PC. This discussion of Windows Vista's major flaws should point out that Microsoft has made a serious error and they need to fix it as soon as they possibly can for they've really got a problem on their hands. Thanks for the help in shuting off this annoying popup. Now I have ANOTHER one warning me that it's off and that I should turn it back on. (no gain) I'm starting to HATE VISTA!!! Bill Gates STOP trying to micromanage my life! I use Vista on my Media Centre for the Media Centre functionality..Nothing Else. My laptop is XP (Soon to be replaced by a Macbook...) and my Main PC is XP. All three systems are more then capable of running Vista, But I won't be rushing to upgrade my other systems. Why ? You tell me. What does Vista offer me ? Vista's biggest opposition at the moment is XP. DirectX 10 Gaming...hasn't really arrived yet. The widgets in the sidebar are nice, but come on... I find Vista is a more efficient OS then XP, it doesn't leave temp files everywhere. (Something XP shouldn't do anyway??) Dual/Quad Core ? Available in XP. 4GB+ Memory ? poorly implemented in XP 64Bit and Vista 64bit. (My macbook will be running 4GB of RAM on a 64Bit OS...cool eh.) I read of people having problems with the RAM being installed/recognised
