I upgraded my wife's Windows 7 machine, to Windows 8 Pro, about 10 days ago. She's been using it fine ever since.
We typically leave our desktops running 24/7, and just turn off the monitor. This morning she turned the monitor on, and saw the screen with the Seattle Space Needle, and then she pressed the enter key to get to the login screen.
Next she pressed the mouse key.
The mouse moves around fine. But we can't get it past the Seattle Space Needle screen. She replaced the batteries in both her keyboard and mouse recently. So, what's going on? How do we fix it?
