How to create the registry key to restrict access to the registry

The Security permissions set on this key define what Users or Groups can connect to the system for remote Registry access. The default Windows installation defines this key and sets the Access Control List to restrict remote registry access as follows:
Administrators have Full Control

The default configuration for Windows permits only Administrators remote access to the Registry. Changes to this key to allow users remote registry access require a system reboot to take effect.
