"Well Leeky, then you either have a very special PC, or a different UAC / Aero setting. That would be an interesting addition to Win 7, SP-1, a setting to, "bypass UAC for commonly used programs". Maybe that's in there already, I just haven't found it yet."
The best way is to just turn off UAC and create a true normal (limited) account in Windows. Use the "run as" command in your normal account to run programs that need it as administrator. This can be done in most of the NT versions, including Seven, Vista, and XP. UAC was at best a half baked idea that is only a partial stop gap measure for the uninformed to continue to infect their computers with malware. Of course the very best way to not get malware is not to use Windows to surf the internet at all, as Linux works very well for that and is free as well.
Linux (and probably Mac OS X) have mostly used limited accounts by default and have great security compared to windows products for a long time now. Even if you secure windows properly, which very few people do, it will not be as secure as Linux/BSD/Mac (unix type systems or clones). But that is not to say that windows cannot be secured better than they come off the selve than there are. The problem is since almost everyone runs as administrator (UAC is not a true normal user account!) so many types of malware software has been written for windows, modified, that the malware exsists in the wild and is very common, unlike unix type systems. Its so easy to install a trojan on windows, because it exists almost everywhere. The other part of the problem in securing windows better, is some of the terrible middleware that Microsoft has embedded into the operation system, like Internet Exploder (activeX), Outlook, WMP, and Messinger, these are major malware targets for the writers. Best to remove them and use open source alternatives that provide a smaller attack surface, like Firefox/Chrome and SMPlayer/VLC.
The 240 million sold figure is basically a bogus figure. Consider that you really have little choice when you go to the stores like Best Buy, its Windows is all they sell. Could be because of the strong arming of OEM's, and that MS owns a small percentage of Best Buy? Also, 13% of the world's computer's get replaced every year, its hardware, and it goes bad. A few more percent is first time buyers in countries like China and India. Those two figures added together maybe as high as 18%, which is a lot higher than Seven is selling. Admittedly Many computers sell with linux, no OS, or pirated windows in some of these countries. Oddly enough, its still XP that the folks in the Orient want, rather than Seven when they do pirate Windows.
