How to Disable Windows Taskbar on the Second Display
461This video shows you how to disable the taskbar in Windows 10.
The current state of Windows 10 is such that you have two different apps to manage settings; the Control Panel desktop app and the Settings app. Judging by the preview builds that Microsoft has been releasing in preparation for the Anniversary Update, the Control Panel is likely going to be phased out with more and more settings accessible from the Settings app. One new setting to have shown up in the Settings app is a dedicated panel for managing the Taskbar. Windows 10 has possibly the best multiple display support of all its predecessors and as of Preview Build 14332, you can now choose whether or not to show/hide the taskbar on multiple displays, and whether or not you want to show/hide app icons on the taskbar on a second screen from the Settings app.
Connect at least one other display to your system and open the Settings app. Go to the Personalization group of settings and click the Taskbar tab at the very bottom. Scroll down to the Multiple Displays section where you have a switch to show the taskbar on all displays. Turn it off and the taskbar will only appear on your main display.
This tutorial will apply for computers, laptops, desktops, and tablets running the Windows 10 operating system (Home, Professional, Enterprise, Education) from all supported hardware manufactures, like Dell, HP, Acer, Asus, Toshiba, Lenovo, and Samsung.
