According to Microsoft Forum Moderator Ruizell Rey:

To resolve your concern regarding duplicated OneDrive entry, follow the steps below:

1. Search for regedit, and then press Enter.
2. Open HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\​Explorer\Desktop\NameSpace
3. Check if you have several folders under NameSpace.

4. If there are several folders, highlight each folder, and then check the name of the Data on the right hand side.

   

5. If you see multiple folders with OneDrive as the Data, right click on it, and then select Delete.

Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

Solution 2:

I have another solution, since i didn't find the folder ...\Desktop\NameSpace in my registry.

I searched the registry, using the following settings: Search only by Data, text "OneDrive", comparing the whole string. The fourth entry i found was something like this:

HKEY_USERS\[User-ID]\Software\Classes\CLSID\[XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX]

The only thing i had to change was setting System.IsPinnedToNameSpaceTree to 0, then the wrong entry disappeared.

If you try this, make sure you copy the key and store it before you make any changes. You can set the key value to 1 again, if you picked the wrong entry.
