Like if you want to enable Registry editor,
User configuration --> System--> Administrative Templates you have ,"Prevent access to Registry editing tools". Open it..
In the Window that comes you have options to enable or disable your Registry Editing.Similarily it has various other settings options that also you could edit.Donot restart your PC.

The next is to stop the Unwanted Programs to run in the Windows Start up.To change these programs open, Start-->Run-->msconfig.
In the System configuration Utility window goto Startup Tab,There a list is present.U can tick or Untick the process u want and dont want.After editing it Click on OK. The PC requires a restart. After starting a dialog box confirming of these Settings arises.Just click Ok.
