for several years, those complaints continued until everybody was forced to use it. Now it is the most widespread O/S out there. It will happen with Vista as well. Get used to it. You will have to start using it at work and school. If you learn about it and educate yourselves now, you won't be so terribley disappointed later. I have question about this UAC. Even when I turned it off, I was still having a problem deleting a program from my c drive. I don't understand why it's asking me for permission? I am the only user on the account and the administrator? I never even saw where you could enter your password as administrator to give it permission to delete the file. What am I missing or what are steps to enter the password to give it permission to delete? UAC does not make Vista more secure, and the fact that it even exists proves that Windows is still not secure, and instead of fixing the root causes of this, MS decided to warn users about the dangers of what they are doing every single time they do something. UAC is an educational control, and an annoying one at that. As pointed out in a previous comment, the average joe user who this is aimed at does not even bother to read the warnings. Apple was smart and chose BSD for it's kernel and then built the flashy UI on top of that. MS should follow suit.
