Switch Windows By Hovering The Mouse Over A Window In Windows 7 Or Vista

To turn this setting on, just type “mouse works” into the search box in the Control Panel, and you should see an item called “Change how your mouse works”.

In this screen, scroll down and find the checkbox for “Activate a window by hovering over it with the mouse”.

That’s pretty much it. It’ll take a while to get used to the new mode… just remember, the mouse has to be hovered over top of any window to switch focus to it.
