Here is a free software to automatically reduce height of Windows 10 taskbar when a window is maximized. This software is named as “SmartTaskbar“. Whenever you maximize a folder, File Explorer window, some image editor opened on the desktop screen, etc., the taskbar height is reduced automatically and taskbar icons also become smaller. When you will restore or minimize the same window or all maximized windows, the taskbar will come back to the default height, including the taskbar icons.
