If you go to the taskbar properties, on the navigation tab, the first option in the "Start Screen" list: Is it checked? If yes, try unchecking it and hitting the OK button.
I am using Win 8.1 on my HP Desktop computer. I have my settings to Open to the Start Screen. However, whenever I open a Windows 8 App (like Mail, People, Games etc.) when I close them it automatically reverts me to the Desktop (Even though I was on the Start Screen when I opened it.) How can I get it to stay on the Start Screen when closing a Win 8 app?
