Microsoft Removed The Old Class Windows 7 Explorer?

In windows vista and windows 7 Microsoft removed the old class Windows Explorer .The old class Windows Explorer .Show a root directory ( The root directory is the highest directory level of a disk. The files and folders you see when you open (double-click) your hard disk icon are the contents of that disk's root directory) and windows explorer the displaying of directory tree hierarchyThe only thing that comes close to old class Windows Explorer is when a user click on computer ( for old windows user called my computer) and you see drive and you click (C) and + under C on split-pane, list on left .ut this crude way of doing it and when user types in run/search box in start manue it takes you to a more user profile page of things for user to work with than the admid will work with.

The old class Windows Explorer like computer ( for old windows user called my computer) is some you really did not want computer novice or young kid to go into.That why in old windows OS computer novice or young kid use my documents folder on the desktop and to run programs click start than all programs and click on the programs in the list and the admid will lock out of other areasThe Windows Explorer back in windows 3.1 was file manager this was not for novice or young kid to go into.Why is Microsoft changing this.
