If you wish to add Control Panel to your start menu,
create a new folder (see tip 051)
and name it
Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}
You will need to reboot to see Control Panel on your Start menu.
Another way to add Control Panel to your Start menu is
to use TweakUI. From the Desktop tab, right click on Control
Panel and Create as file. Save it on the menu (see tip 051).
You can do this for Printers also.
