It is a nice tutorial.
A long time ago, at the beginning og the Vista testing, I wrapped this up in an automatic .reg file. I do not take credit for it, as several people came up with the same idea. It is now widely distributed on the web. It works the same way in Windows 7.
What this .reg does, is inserts a right click mouse option on any file/folder, you wish to control.
A word of warning to users, some folders in Vista and Windows 7 are not meant to be interfered with (Documents and Settings, for example) To take control of these folders, known as junctions, can have bad consequences.
I have enclosed the .zip, which also includes the undo .reg
