Quick Settings

Quick settings appears when you click the "Network," "Volume," or "Power" icons in the Taskbar's system tray. As its name suggests, Quick settings provides quick access to commonly needed system settings like Wi-Fi, Bluetooth, Airplane mode, Battery saver, and more.
Keyboard shortcut: You can also open Quick settings by typing Windows key + A.
That the

The "Network," "Volume," and "Power" icons working as one is unique. But they behave more typically when you right-click them. Each displays a different context menu that is relevant only to the icon you right-clicked.

Defaults
Quick settings is non-resizable interface with few settings you can customize. It displays a scrollable grid of quick settings buttons, six of which are visible at a time, Brightness and Volume sliders, a "Sound output" button, a Battery life icon that opens the Settings app to System > Power & battery, and an "All settings" (gear) button that launches the Settings app to its Home page when clicked.
Tip: Quick settings is sometimes customized by your PC maker to include a custom icon that launches its support app when clicked. This icon will appear to the left of "All settings" if present.
To close Quick settings, click anywhere else on-screen.
Keyboard shortcut: You can also close Quick settings by tapping Esc.
Customize
Quick settings supports just a single customization capability: You can reposition any quick setting button by dragging and dropping it with your mouse.

There is no way to remove quick settings buttons you don't want. The best you can do is reposition them at the bottom of the last page of quick settings buttons.

Also, it's likely that your PC won't have every possible quick setting button because some are tied to specific hardware configurations. Cellular quick settings requires a cellular data connection, for example, which is unusual in PCs.
Understand Quick settings
Quick settings is a simple, useful, and mostly obvious interface for accessing key system settings without needing to open the Settings app and search or click around to find what you need. But there's a lot of functionality in there.
Quick settings buttons
Quick settings displays six quick settings buttons in a grid at its top, but there are more pages of buttons you can't see unless you scroll down. So it provides a pips pager control on its right for navigating between the available pages of buttons. To do so, click a specific pip (circular dot) on the control, click the "Next Page" pip to scroll down one page, or, if you have a touchpad or mouse with a scroll wheel, you can use that to scroll while the mouse cursor is over the grid. When you scroll down, a "Previous Page" pip appears at the top of the control for navigating in the opposite direction

Most active quick setting buttons display using the accent color you configure (in Settings > Personalization > Colors), while most inactive buttons use the background color. Either way...
