UAC General comments
Two things about UAC that many users do not seem to grasp are, No. 1: UAC does not "scout ahead" and come back and tell you that the website that you are indicating you want to go to has been previously known to "give you bad stuff", or any such warning as that. It only follows your keystrokes and as a result of a keystroke or series of keystrokes, pops up in your face to tell you that you are requesting a website or a computer change that has the potential, or the ability to be or to deliver "something ugly". UAC does not warn you when you are about to download a virus or Trojan or such, or hose your system, it only warns that the potential exists. If you didn't already have confidence that you were making a desired change to your computer, you would not have "been where you were" to have gotten the prompt in the first place. Therefore, you are going to click, "OK" and UAC has done nothing more than irritate the user. No 2: once you have clicked OK to the "in your face prompt", if a Trojan or virus is riding along inside whatever you are downloading, UAC will not know or care. Hopefully, your antivirus will catch the bad guy, but UAC is worthless for determining what is a good guy and what is a bad guy.
Due to these two conditions, UAC is nothing but an impediment to smooth computer function.
That's my story, and I'm stickin' to it!
