You could have uploaded the UUP files like Enthousiast did, then you wouldn't be breaking the rules. That looks ugly, black font with dark theme enabled and the user picture at top should be a bit lower. I know this is very far from finished.
There is a difference between x64 and x86. The one you link to, the UUPs, is just x86. The other is x64 which I downloaded, set to install default Insider Start Menu, and converted to Enterprise, and ProWorkstation. I also made an AIO size 3.33 GB. Easy enough, but life is good so why not test new builds? The last I remember you can't test a build with only a screenshot!
Absolutely not true. Just because sfc /scannow (totally useless operation IMHO) doesn't work doesn't mean it is crippled. So many people use that term loosely. One little bug and the whole OS is shot to hell. I am using 18947 xbox right now, and it is way far far away from crippled. In fact it runs quite well. I am on ProWS and even have Sandbox enabled. I also have Office 2019 installed, and activated. RSAT is present also. All in all, I am happy.
