You support laptops that run Windows 8 Pro and are part of a workgroup.
An employee is unable to start Windows Mobility Center on his laptop.
You need to make it possible for the employee to use Windows Mobility Center on the laptop.
What should you do?

A.

B.
Use Turn Windows features on or off in Programs and Features to enable Windows Mobility Center.

C.
Use Programs and Features to repair the installation of Windows Mobility Center.

D.
Use Local Group Policy Editor to set Turn off Windows Mobility Center to Not Configured.

Explanation:
Original answer ‘A’ however, I reviewed in lab and could not find Windows Mobility Center within Windows
Features options.
User Configuration > Administrative Templates > Windows Components and Windows Mobility Center If you
Enable the Turn off Windows Mobility Center setting, the user is unable to invoke Windows Mobility Center.
The Windows Mobility Center UI is removed from all shell entry points and the .exe file does not launch it.
If you do not configure this policy setting, Windows Mobility Center is on by default.
