Alt+Tab Tuner makes it easy to customize the size and layout of the thumbnails on the native Alt+Tab window switcher in Windows 7. Slide the settings to the perfect value and click Apply. Make sure to enable the Autorestart Explorer check box for instant results. Otherwise you will have to reboot your computer.

But with this program, I pressed on "Old Style Alt+Tab Dialog" and it's not very good. So I tried switching it back by unck=hecking it but it stays as the old one, wheather it's checked or not. HELP!!!
Thanx :)
