One of the recent changes in Windows 10 Anniversary Update is that the icons in the Quick Action area in Action Center are highly customizable. You can add, remove and re-arrange the position of the icons in Action Center.
Here is how you can do it.
Fire up Settings app, and go to System → Notification & actions.
To add or remove icons from the Action Center, click “Add or remove quick actions” link and set the items you want to add to the Action Center to On and the items you want to remove to Off.
By default, the icons are laid out in the Action Center in a first-come-first-serve fashion. If you turn off all the Quick Action icons and start turning them back on one by one, the one turned on the first gets the first place in Action Center and so on so forth.
Now, Anniversary Update added a new feature that allows us to re-arrange the icons freely without turning them on and off. Simply press and hold the icon you want to re-position and drag & drop it to the new location. The change will be immediately made to the Action Center.
That makes it a lot easier and convenient.
