One of the most visible changes in Windows Vista is the complete redesign of the Control Panel. Lots of things were moved and now you have very easy access to some configuration options while others seem to be hidden deep in the Control Panel menus.
If you have a hard time finding things, don’t worry. Windows Vista gives you the option to switch back to the old Control Panel and this is how you do it:
Go to Start -> Control Panel .
If you look carefully, you will notice that in the left side of the screen there is a panel with two options. The first option is Control Panel Home and the second is Classic View.
Click on Classic View and the Control Panel will be reloaded and will look just like the old one from Windows 2000 and XP.
