Full Screen and Lens mode in Magnifier Windows 7 Enterprise grayed out

Problem:

Full Screen and Lens mode in Magnifier Windows 7 Enterprise grayed out as shown below.

enter image description here

OS:

C:\>systeminfo | findstr /B /C:"OS Name" /C:"OS Version"
OS Name:                   Microsoft Windows 7 Enterprise
OS Version:                6.1.7601 Service Pack 1 Build 7601

Found link on Microsoft, but didn't help at all.

Then, I also found almost similar problem here … but he is using Home edition while mine is Enterprise version.

Windows 7 Basic Magnifier "Full Screen" option grayed out

According to the answer …

From the help file (press F1):

"Full-screen mode and lens mode are only available as part of the Aero experience. If your computer doesn't support Aero, or if you're

using a theme other than an Aero theme, Magnifier will only work in
docked mode."

I am sorry, but Home Basic does not include Aero. From the following
link:

"The Aero desktop experience, available in the Home Premium, 

Professional, Ultimate, and Enterprise editions of Windows 7…"

So, this doesn't apply to my case as I'm using Enterprise version, not Home edition.

What did I do?

I have also tried the solution here including modifying the registry but none of them worked.
Windows 7 magnifier not fullscreen

What should I do to fix this problem?
