Normally in Windows Vista (and any other previous version of Windows) you can switch from one window to another by just clicking with your mouse on it, right? But what if you could do the same by just hovering over the windows your mouse? This way it’s easier to switch between windows.

So to enable this option you have to follow this step:

1. Open the Ease of Access center by pressing Windows Key + U
2. Now Under Explore all settings, select: Make the mouse easier to use
3. In  this screen you’ll see the option which you have to active by checking the box: Activate a window by hovering over it with the mouse
4. Now save your new settings and your done.

I don’t know if you’re going to like this option or not but give it a try! Anyway… it’ll take a while to get used to the new mode and if you don’t like this.. You can always turn it off by checking the checkbox off!
NOTE: The mouse has to be hovered over top of any window to switch focus to it.
