After my Windows 7 returns from a hybrid sleep, it shows the desktop instead of the logon screen.
How to fix this?
There is an option at your energy options. On the left side of the Window you can find something like "passwort on activation" or something. I only got a german Windows version so I cant tell you the correct name of the option. But there you can set a checkbox "password needed". After activation you will need to enter your password while waking from sleep mode.
