When you have OneDrive for Business installed in Windows 10, you get a nice OneDrive for Business Icon. For those of us who have remapped (relocated) the Windows Libraries to our end users OneDrive for Business accounts, this becomes a redundant icon. To remove this icon you need to go into the registry editor and navigate to:
Alter theSystem.IsPinnedToNameSpaceTree to the Value of 0
If you just want to rename the icon, change
(Default) to the Value you wish the icon was named.
