I am using Windows 7.
Windows-L hotkey shortcut takes me to a blank Windows screen telling me to press
Ctrl-Alt-Del to unlock the computer (requiring my password).
I want to override this behaviour so that it activates my screen saver instead, and then when I move the mouse, it will prompt me to press
Ctrl-Alt-Del and enter my password.
I can't seem to figure out how to change this - any ideas?
