Hi Khen,
Okay, this will be a 2 part fix, we will do this for the Documents folder to ensure it works correctly
1
Open the Registry Editor again
Double click {F42EE2D3-909F-4907-8871-4C22FC0BF756}, set its Value Data to this and click OK
%USERPROFILE%\Videos\Documents
Double click Personal, set its Value Data to this and click OK
%USERPROFILE%\Videos\Documents
Close the Registry editor and restart your PC
2
Open File Explorer, then right click the Documents folder and select Properties, it now should have a Location tab
Click Restore Default on the Location tab and wait for that folder to move
Is that successful?
