"I am on Vista, and doesn't yet have Win 7"

Does UAC on Win 7 not have a "quiet mode", like Vista has?
Snap from WinAbility:

I don't believe UAC ever was invented to help the user. UAC is exactly like the EULA; it is there so that in case there ever will be a trial, they can claim, "oh, but we told you so!" And that is of course all the UAC as well is for. It was solely invented so Microsoft can keep their back in the clear no matter what ugliness gets into your computer: "Oh, but we told you so!". I have not seen the UAC pop-up since the day I installed the TweakUAC™, and I never looked back. Of course, I then have other programs to do the necessary job, but they also do it much better than I could do it. Because as it was said earlier in this thread, after a while, with UAC, you just confirm without reading what it is you are confirming.
I don't know if any of these UAC tweakers are ready for Win 7.

Regarding the Control Panel. It is a good idea to have it show up as a menu, rather than as a shortcut. My Vista was installed by a third party company, which, if you will forgive me the hight, gave me this quite awesome control panel menu (in Danish):
