I now have update 1 for Windows 8.1 and it was another massive download taking AGES (around 1/2 gig). It's on a computer that doesn't get much use so it'll be a while before I make up my mind on this upgrade. There's a button on the screen to shut down the computer and a search box. I tried Search by putting in "Device Manager" and unfortunately it couldn't cope with that. Not an impressive beginning. It did manage to find Control Panel though which is always useful. I've uninstalled Classic Shell to show willing and see if I manage without the familiar Windows look.
