well done :-)
I got a mouse connected and played around with some of the settings. There's no driver for the built-in WiFi chip, and I didn't find this guide
with instructions on how to pre-configure the ethernet port to work until after I started flashing the image (which took 40-50 minutes), but I did manage to transfer the drivers onto the device using a thumb drive and got ethernet connected now.
Interestingly Windows activated itself automatically even though I didn't enter a license key or anything like that. I'm now attempting to download Windows Updates and we'll see if that will even work. It would be interesting to see if it will update from the version I installed (1803 build 17134.1) to a more recent version (1809) and still work properly. But I think that might not be possible in my current setup, since I used a 16GB microSD card for the installation and there's only 4GB of free space left.
And there's no GPU acceleration, so everything is fairly sluggish. Even so, it's kind of amusing to see running. There's something satisfying and amusing about getting something to run on hardware it was never really meant to run on.
