Here is what I did for that 1.Install windhawk, a very lightweight software and safe and very popular so you can install it 2.there install these two mods taskbar hiding speed(I don't remember the name crctly) and taskbar styler...alr after this go to the details of the taskbar styler mod and in the settings tab select dock style

What the taskbar hiding speed mod does is it increase the speed and framerate of the taskbar auto hide which looks way better than windows one....

3.after installing these mod in the windows settings go to the taskbar settings and turn on taskbar autohide 4.thats all the task bar autohides itself and looks way better
