Windows includes a special application desktop toolbar called the taskbar that shows on the bottom of a display screen by default. The taskbar allows you to find, see, open, and switch between your apps. You can also see the date and time, system icons, and items running in the background on the notification area. You can make the taskbar look how you want, manage your calendar, pin your favorite apps to it, change the size, move it to where you want to display on your screen, and specify how taskbar buttons group together when you have more than one window open.
When the taskbar is unlocked, you can resize the taskbar, move the taskbar, and rearrange any toolbars on the taskbar.
This tutorial will show you how to enable or disable the ability to unlock and lock the taskbar for specific or all users in Windows 10.
