You have no right-click menu on the Desktop because you have no Desktop - it's part
of the bargain. To get the Recycle Bin to your Quick Launch menu, undo the Registry
change (just change the value to zero, you don't have to delete the key), then when
you get your Desktop back drag a shortcut of the Recycle Bin to Quick Launch. Then
re-modify the Registry NoDesktop key again if you want.
