Windows Mobility Center not opening in Windows 7

Problem

You try to open Windows Mobility Center and it is not opening. It can be opened from either the Start menu or by pressing Win + X and neither method works.

Solution

Open Task Manager or Process Explorer and see if the Windows Mobility Center is already running. Look for the process named mblctr.exe and kill it. You should be able to open it after this.
