Windows Server 2019 and Windows 10 with new Hyper-V VM Version and UEFI
If you are running the latest Windows Insider builds, for example in Windows 10 Build 17728 and you are running Hyper-V you will see two new improvements. These improvements are also in the latest Windows Server 2019 Insider Preview builds and will be available for production when Windows Server 2019 will be released.
Microsoft Hyper-V UEFI 2019
First Hyper-V UEFI now looks prettier and has more less the same still as other Microsoft devices like the Surface Book or the Surface Pro.
Lars Iwer from the Hyper-V team also mentions that the new error messages should be more help full.
Not sure if a lot of folks noticed: Hyper-V’s UEFI as part of the Insider preview has prettier and hopefully more helpful error messages when something goes wrong: pic.twitter.com/HPgr1W7x9Z

Windows Server 2019 Hyper-V VM Version 9.0
The second change you can notice is that in the build you will fine the new Hyper-V VM Version 9. In the Windows 10 April 2018 Update (1803) Hyper-V had the VM version number 8.3.
You can use the Update-VMVersion PowerShell cmdlet to update the Hyper-V Version from older versions of Hyper-V to the latest.
