The Taskbar appears aligned at the center of the screen, introduces a new Start button design as well as new buttons for Search, Task View, Widgets, and Chat. You will notice new animations, and Microsoft has even added some work to the system tray.
However, to make this version a little simpler, Microsoft ended removing many useful settings, making the Taskbar a lot less functional. For example, even though you can change the alignment of the Taskbar, it's no longer possible to reposition it at the top, left, or right side of the screen. You cannot show labels, hide the date and time, change the icon size, and more.
If you like the desktop without the Taskbar, you can still enable the option to hide the bar automatically when it's not in focus.
Also, starting with this new version of Windows, you can no longer access the Task Manager from the Taskbar right-click menu. However, you can use these tips to find different these ways to keep access the app from the Taskbar, Start menu, and Desktop quickly.
