God Mode or admin’s power panel in Windows 7

The magic word is Admin.{ED7BA470-8E54-465E-825C-99712043E01C}.

Create a new folder in any folder you like (make it root folder on your first drive or deeply hidden secret dir) and use exactly above string as folder's name. Folder's icon will change to confirm that you've succeeded.

Double clicking this folder -- instead of showing contents of empty directory -- will give you an access to a really impressive list of shortcuts to most powerful and hidden features of Windows 7.

Happy hacking, folks!
