2 empty folders still appearing on desktop even after deletion

This issue may be caused by Office 2013 installation and uninstallation. The following shows the steps to delete these folders completely with the aid of the long names.

1. Click the Windows Start button, and type in regedit in the search box, then press Enter.
2. Navigate to

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace

and expand the NameSpace branch.

3. Delete the following branches:

0875DCB6-C686-4243-9432-ADCCF0B9F2D7

138508BC-1E03-49EA-9C8F-EA9E1D05D65D

I found an advice to look up registry. Pressed "Windows+R", typed "regedit". And then just searched for "::{0875DCB6-C686-4243-9432-ADCCF0B9F2D7}", and deleted every key found. Seems like OneNote and Groove's registry entries. Actually I've installed MS Office 2013 several days ago. Folders removed and not appearing.
