Have installed this new version on 2 PCs.
The laptop (dell) working fine AFTER the second installation (from ISO)
First installation problem: DxC19D0101 - Dx3D018 installation failed in phase FIRST BOOT with error during SYSPREP SPECIALIZE
The desktop (asus) installed fine but completely freeze after a few minutes at first (and 8 other) boots (even enable to ctrl-alt-del, had to power off/on)
After one reboot I just had time to change msconfig to safe mode boot and than restore to Windows.old)
After restoring to window.old (1909) all is fine again.
Have tried to update a HYPER-V windows 10 1909 EN-US X64: no problem found
