Windows 10: Anyone Have problems with Hyper-V on Server 2019 1809 after August 2020 patches

We've been having problems after installing August 2020 Patches on our 2019 HyperV hosts. We have multiple hyper-v clusters across Dell VRTX and UCS blades w/ ISCSI backend SANS. Both environments have seen backup times double. Additionally loading a VMs settings in HyperV or Failover cluster manager is taking a very long time. We are not using a 3rd party AV but defender managed by SCCM


Patches applied
KB4566424

KB4565349

KB4569776


Other Changes

None that i'm aware of


I'm going to try roll back the august patching to see if that remediates the issue but thought i'd post to see if anyone else has seen this issue.

Why isn't Microsoft Hyper-V Server 2019 on the Microsoft Evaluation Center

I am aware that there were some issues with the Windows Server 2019 evaluation media after its rerelease on November 13, 2018. I am also aware that the issues are fixed and Windows Server 2019 Standard and Datacenter ISO is back. However, Hyper-V Server
2019 is not out one week later. If you go to https://www.microsoft.com/en-us/evalcenter/evaluate-hyper-v-server-2019 you will not be able to download it. If you go to hyper-v-backup.backupchain.com/windows-server-2019-iso-free-download-hyper-v-server-2019/
you can download it using Microsoft links. Has Microsoft forgotten about Hyper-V Server 2019 or is there an issue with that too?

Hyper-V Server Core 2019

I did temporary install of hyper-v server core 2019 but was left bemused as to how we're supposed to administer system properties locally.

How do I manage System Properties or other Control Panel items from the command line?

There doesn't appear (on disk) to be a pagefile created and got me wondering how to manage such things. Also, automatic driver installation and system protection settings.

is there a *printable* reference of PowerShell commands and other admin utils?

lastly. Why isn't there a dedicated forum for Server admins?
