Hello 88King, and welcome to Seven Forums.
It depends on if you use Windows Explorer with the
Show all folders option checked or not for what option in the tutorial to use to have the Recycle Bin display.
You would only have the "Wow6432Node" key in a 64-bit Windows 7, and not in a 32-bit Windows 7.
If the other computer is a 32-bit Windows 7, then you would not do step 9, and only do the tutorial at the registry location below instead.
HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\ShellFolder
You would want to remove what you added to the registry location below as well.
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\ShellFolder
Hope this helps for now.
