Sorry for not responding to your question. I’m not frequent in here as my Chuwi performs very well – still no issues. Some small wifi-drops now and then, but that’s mostly related to number of users on my home net it seems.
Dowloaded the iso from Windows offical site, just search for it and you’ll find it – make sure it’s the correct version. I have bought a few Windows licenses, so I probably did use one of them if I remember correctly.
My keyboard is a bit annoying as it isn’t straight, one corner hangs down a little just as in Techtablets video. It’s the metal newest version so the touch pad is good and typing is also all right except the space bar sometimes miss the press and doesn’t register. Looks like this happens when I’m close to one end of the bar.
But value for money as a cheap hybrid is great – IF one expects performance and quality according to price. It is not a Surface Pro 3. Battery life and screen colors/brightness is the best features for me. I typically use it for browsing and email, but have also been using the stylus some. Tried a few games which is not impressive, but Euro Truck Simulator runs fine (Steam installation). In fact, the main thing I’ve been using it for lately is streaming games from my Xbox One S which works excellent. Connecting the xbox-controller through bluetooth. Really smooth.
