To add the "Rename" option to the Recycle Bin when right-clicking on it, open Notepad and copy these lines into it:
REGEDIT4 [HKEY_CLASSES_ROOT\CLSID\{654FF040-5081-101B-9F08-00AA002F954E}\ ShellFolder]"Attributes"=hex50,01,00,20
Name the file 'BIN.REG' then double-click on it to add it to the registry. You can now right-click on the Recycle Bin and rename it to whatever you would like.
