Eugene from Chino California asked us: “Is there a simplified tree, maybe in several pages, to show what is in Windows 7 in such things as the control panel or any of the solution devices which are used for maintaining a PC?“
We thought that was a great idea and decided to do a special series. In part one we looked at System and Security.  In part two we checked out Network and Internet.  Part three was hardware and software . Part four was Programs . In part five we saw User Accounts and Family Safety. 
For part six, we’ve got a look at Appearance and Personalization.
I hope that this helps.
