There are many ways to accomplish almost anything in Win 8. I did try this method, but found drilling down to the item I wanted just seemed to take me too long. This is one reason why I installed Classic Shell. I have control Panel set as a Menu Item. With this I click on the Classic Shell Start Shell (instead of orb, it is shell shaped), Hover my cursor over CP and it opens. Fewer clicks saves me time.
The reason I customized Win 7, and now Win 8 RP was to make my life easier. These customizations are not "necessary" but makes my job somewhat easier for me. All the hubbub about having to customize Win 8 RP is irrelevant in my case, as I spent as much time customizing Win 7 as I have Win 8 RP. The Win 8-Style UI versus Desktop UI is a less than 30 second change. You just move the Desktop Tile to the upper left. You do have to hold down the Enter key for a couple of seconds when you first sign on, but that is a non-issue.
