Windows Mobility Center (mblctr.exe) is a special app that comes bundled with Windows 10. It is present by default on mobile devices like laptops and tablets. It allows changing brightness, volume, power plans, screen orientation, display projection, Sync Center settings, and presentation settings of your device. By default, the ability to run the app is restricted to mobile devices only. It doesn't start on desktop PCs. Here is how to unlock it on a Desktop PC.
Windows Mobility Center was first introduced in Windows 7. Windows 8, Windows 8.1 and Windows 10 also include it, however it is mostly superseded by Action Center's buttons for quickly toggling these above mentioned settings. Still if you prefer to use Mobility Center, you can activate it on a Desktop computer. It can still be useful because it can be extended by OEMs (your PC vendor) with additional tiles to toggle various system settings like Bluetooth or your monitor.
If you try to launch Windows Mobility Center on a desktop PC, it will show the following message:
Windows Mobility Center is available only on laptops.
