Open Regedit (Start- Run- Regedit) and choose or navigate to
HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft Windows/CurrentVersion/Explorer/My Computer/NameSpace/DelegateFolders
There will see a sub-key from registry named {645FF040-5081-101B-9F08-00AA002F954E}\ShellFolder.
Change its attributes, HEX to "50,01,00,20" and DWORD to " 00000000".
And reboot or restart the PC.
If you want to turn this trick off, you just need to change HEX code to "40,01,00,20".
