Why does WS want so much space now?

Why does Windows Server needs 400 GB for the system partition now (this is from Server 2019)? A basic hypervisor installation uses less than 40 GB on the system volume.

I'm not sure on this one, nothing has changed in the context of Windows Server system partition requirements. 400 GB is not required, and it looks like just a warning for a recommendation that you can bypass. It could be a bug, would need investigation. Obviously a huge number of Windows Servers are running in VMs, where this makes no sense.

Yes, you are right, this is just a warning, still a bizarre looking one. Could you please file an internal bug regarding this?
