Delete Shared Documents Folder

I wish to delete the Shared Documents Folder. This involves the deletion of a
registry key (tricky operation) and therefore request confirmation of correct
proceedure.
The key to delete is found in:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Explorer\MyComputer\NameSpace\DelegateF olders
Details of key: {59031a47-3f72-44a7-89c5-5595fe6b30ee}
When double clicking the key the following message appears:
"Are you sure you want to delete this key and all of its subkeys?" YES/NO.
Kindly please advise if it's okay to click YES to delete the Shared
Documents folder in a safe manner for good.
Also, would it be be beneficial to set a System Restore Point just in
case.....?
Thank you in advance for assistance.
