One of the most controversial changes in Windows Vista is the redesign of the way in which you can shut down your computer. The Log Off
and Shut Down
buttons are no longer in the same position even if the new buttons in Windows Vista may give you the impression that they have the same functionality.
So... where did the Shut Down
and Log Off
If you take a closer look, you will see that near those two big buttons there is a small “arrow like” button. If you press on it, a menu with 7 options will appear. Log Off
is the second from the top and Shut Down
is the last.
