Help!
Some additional information:
I want to show Administrator account in safe mode only, just like in XP.
After a few trails, I think this is not quite possible, so I am trying to find an alternative, that is like this.
Previously on XP, you can press Ctrl+Alt+Del 2 times to show the traditional logon box, but it is disabled in Windows 7, so I wonder how can I logon those hidden users, like Administrator, without showing it on the list in normal mode.
