But for networks and businesses as well as single users, the UAC is just simply ridiculous. Businesses probably already have filters and good network security programs that they've paid thousands of dollars for. So why would they need this crappy version of security that limits everything when they already have a $20,000 network security program as well as security hardware for their network. The point is that they don't. Also, if you run a LAN in your home, one would think that the computers on the network would be run by people smart enough to use a computer on their own without having to be constantly pestered by the UAC. If there is a family using a network of Vista-enabled PCs, one would think that the parents would only give the children a computer of their own if they were smart enough and responsible enough to handle a computer and not ruin the files or software. Surely the parents know that, and they should teach their children that as well. In my personal experience with Windows Vista, I have to say that it's basically the worst operating system I have ever seen in my life. I want Mac OS10 Tiger, Windows XP Professional, or Fedora Core Linux instead. These operating systems work well and trust the users to do the right thing with their own security. After all, would a person use a computer and not have ANY idea what they are doing with the computer? No, I think not.
