I get rid of the large Cortana search box and replace it with the Search icon or remove it completely.
Right click on the Taskbar, point to Cortana then select Hidden (my choice) or Show Cortana icon.
Right click on Desktop, Themes, Desktop icon settings. Check all 5 boxes then Apply and OK to get system icons on the Desktop.
In Themes, I also pick a Theme or download a new one from the internet.
Right click on Taskbar, Properties. Click on Customize. Click on Select which icons appear on the taskbar and turn on Always show all icons in notification area.
