In order to download Windows 10 you need the Windows 10 upgrade app that places a little windows logo on the bottom right corner of your screen. I’m running Windows 8.1 and do not have this logo on my screen. My searches on how to get the Windows 10 upgrade app have only turned up confusing articles and threads. Does anyone know how I can get the Windows 10 upgrade app so I can make a reservation to get Windows 10?
run this and choose “upgrade this computer”
