RE: Windows Switcher
I believe I found a solution to the problem.
-Open your Control Panel and go to Appearance and Personalization.
-Click on Window Color and Appearance.
-Under the Appearance Tab, make sure your Color Scheme is set to Windows
Aero. If you do not see this tab, then go to the bottom of the screen that
comes up and click on "Open classic appearance properties for more color
-When your color sheme is set to Windows Aero you can now check the box
-When you do this, your Window Switcher should return to how it was before.
I hope this is helpful and let me know if this does not work for you.
