I’d upgrade if I could.
I have one 2-in-1 laptop/tablet device that just won’t even offer me 1903; it’s determinedly stuck on 1803 - a virgin installation, no extra software at all. Must be some weird hardware or crappy firmware. Maybe I should contact the manufacturer to find out why it doesn’t play nicely with Microsoft’s Windows 10.
The device is called a “Surface Book”. I wonder who made it.
