Just finished installation. Overall, it's still early days. There's a ton of legacy Windows lying around. But the rounded corners are good. Those having issues with Mega, just temporarily use a VPN extension for your browser when you hit the quota, resume download, and turn off the VPN to continue downloading at native speeds.

Yes but I booted using Strelec WinPE USB and used NTSetup 4.6 to make image based install. Booted right into Welcome Screen with region selection. Looks fantastic on 120 hz 4K monitor
I did not pay too much attention to Windows 10X. But now it seems that Microsoft has not completely abandoned it.
