I followed this trick to remove one drive from my PC, use the same with the slightly different way.
To remove the SharePoint pane, press the windows key
and type run
. Inside the run
window, type regeditregedit
. Now go to HKEY_CLASSES_ROOT\CLSID\
inside regedit, right click the CLSID
folder node and click 'Find' enter 'SharePoint' and do the same as they mention in the article. upon finding the search node->Double click this KEY System.IsPinnedToNameSpaceTree
then change value
from '1'
to '0'
Note: This will only remove the icon from windows explorer.
Let us know if it worth to give a try.
