|Regedit||Regedit is an editor for accessing the Windows registry that is provided with the Windows operating system. It can be accessed from the Start Menu ( START > Run > type "regedit" ). Some of the changes to registry keys/values require rebooting the PC before they take effect.
It is a good idea to star the registry editor as admininstrator (right-click > Run as Administrator), as changes to some of the "hives" require elevation.
Note: Modifying some registry settings can cause serious problems and damage your operating system to a point where it needs to be reinstalled. Make backups and use the information at your own risk.
Again, it is always a good idea to backup the Windows Registry before making changes!
