I'm finding it's not updating the 'Location' for anything other than 'Desktop' in Explorer. So the left-hand side dropdown pane in Explorer where 'This PC' can be found; the sub-items here are not working as are still linked to the old location. The redirection worked, just this area wasn't updated for other folders. Can this be fixed? Preferably in script. Thanks.
