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 andWindows 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.
