OneDrive configured and then removed. How do I restore Documents to it's original location?

Solution 1:

Right click Documents then Properties, Location tab, Restore Default button.

Solution 2:

If moving it back to original location with "Restore Default" doesn't work, reinstall Onedrive the same way as it was before. Then try restoring the location, and once that's successful uninstall Onedrive.

Solution 3:

I suggest you try to check the related registry.

Locate to Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders, then find the "Personal" value. Make sure its data value is C:\Users\Mom\Documents.
