User Interface Transition from Windows XP to Windows 7

Windows 7 Build 7000 Control Panel 1

Here's Windows 7's Control Panel. I can see why Microsoft did this so as to introduce simplicity by grouping functions, but for a veteran user, it's frustrating. It also requires an additional click to see all the menu items. Hovering over each menu item yields a text description that you need to read to see what is contained below, however, I think they could have simply had the other icons from the next level down appear for each grouping when you hover, or use a paradigm similar to the MMC where you have an expandable tree list.
