Hello Mike, sorry to hear you're having trouble.
This could be due to a couple of things. First, check to make sure your PC is not in tablet mode. To do this go to Settings by right clicking on your Start icon and select Settings. Then type Tablet in the search bar. You can check the system there to make sure that's not the issue. If tablet mode is turned on then turn it off and restart.
Another thing to check is that your icons are enabled in the task bar. Open Windows Settings by pressing the Windows Key+I. Type Taskbar in the search bar and then click enable for any icons you want to see.
