b-man seems you put the wrong regfiles in your zip.
BenQuilter if you perhaps change your mind from time to time and would prefer to have a rename option in the rightclick menu of the recycle bin here is the way to do it:
open regedit and find the key
Select this, on the right there's a binary value called Attributes. Rightclick it, 'modify'. Instead of 40 01 00 20 it should read 50 01 00 20 to have a 'rename' option. In XP, you'll also need to edit the dword string called "CallForAttributes" there. Set it to 0x00000000 (0).
To give it no name then rightclick, choose rename and press the space key. Should work.
