you just change something in your registry rather easy actually
go to run>regedit.exe>HKEY_CURRENT_USER> software>microsoft>windows>current version>policies>explorer
create a new DWORD named NoDeskop, once made go right click on it, modify and change value to 1, then close explorer.exe and open it back up, just change to 0 or delete the DWORD you made to make it go back
