Windows Mobility Center

Windows Mobility Center is a component of Microsoft Windows. It serves as a quick way to adjust frequent parameters on laptops such as brightness, volume, or the power state.

History
Windows Mobility Center was introduced in Windows Vista build 5231 as a basic application that could be launched from Control Panel. It contained multiple tiles, each one showing different mobility parameters such as display connections and brightness, speaker volume, battery status, and presentation options. It was also open to customization, so that OEMs could add their own tiles, which would all appear under a "Customized by" heading. Individual developers could create their own tiles as well.

After the RTM of Vista was released, there were no major changes to both the interface and functionality, being the only notable the removal of a tile in Windows 8.

Mobility Center is a window with special transparency, meaning that Aero glass effects would cover it entirely when used. Otherwise, a blank background with a small blue fading on the upper side below the border. After Aero's removal in Windows 8, accent colors replaced full transparency as those covering the window when enabled.

How to find it?

 * In Control Panel's Hardware and Sound category or on the link contained in Classic Views.
 * Through the ⊞ Win keyboard shortcut.
 * Starting with Windows 8, this hotkey will launch the Quick Link/Power User Menu. When it appears, click the second link from top to bottom on the list to open the app.
 * By typing  in Run.
 * By right clicking the Power icon on the taskbar's notification area and selecting Windows Mobility Center.

Enabling it on desktop computers
If a desktop computer user attempts to launch Mobility Center via any of these methods, a warning will pop up saying "Windows Mobility Center is available only on laptops" and blocking access to the app, as it is required that the computer has a battery for it to properly launch. However, it is possible to bypass this warning and manage to open the app by either plugging an uninterruptible power supply (UPS) or merging the following to the registry:
