To find or change any entry in the registry, use Registry Editor. Once you have opened Registry Editor, you can proceed to rename a registry key or value.
Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on your computer.
If you make a mistake that results in your computer not starting properly, you can restore the registry. For instructions, see Restore the Registry.
|To rename a registry key or value|
