You can try the Aero troubleshooter.

Open Control Panel/Troubleshooting. Under Appearance and Personalization, select the Display Aero desktop effects.

In the Troubleshooter dialog, click the Advanced link and place a check mark in the Apply Repairs Automatically option.

Click Next to run the troubleshooter.

Set up an Aero theme then try again. I would guess that you haven't got the Aero theme active!
Right click on your desktop and choose "Personalize" and then choose an Aero theme.

Thanks, I got the Aero theme active, however same result.

I tried "the Aero troubleshooter", and found wddm driver, so I changed driver.
After checking "the Aero troubleshooter", I open Aero peek option box, then same result.

Mitchell you are my hero. I have been reading forums for about two hours and almost shat myself when I read this post. Such and easy fix. I have been checking/adding registry, service and visual settings to no avail. Thanks for the advice.
