Ok, since I have Windows 8 couple of months, I would like to share some things with you.
First of all, it took me some time to find out where shut down, restart or log off is…
Log off (sign out) or switch user
On Start screen / Metro screen, right click on user:
Quick access menu
right click on the left bottom corner
Get list of all apps
Logon to Desktop not Start/Metro
Click finish, restar and test it out.
