Windows 10: Hyper-V breaks after installing the Jan 2022 Windows Update on Windows 8.1 KB5009624

Today is Jan 11th, 2022. After I applied the monthly patch on my Windows 8.1 machine, the local VMs no longer work. If I uninstall the patch KB5009624, the VMs started to work again. Please help.The error is "virtual machine could not be started because hypervisor is not running".

Where is the Hyper V Manager, How to I start it ?

I am trying to setup an XP virtual Machine on Windows 10 Pro.

I followed the steps in Neil Peterson article of 5/9/2016.

System Requirements - done - ok

Install Hyper-V - done - ok

Create a Virtual Switch - skip

Create a Virtual Machine

Create a Virtual Machine with Hyper-V Manager

These steps walk through how to manually create a virtual machine and deploy an operating system to this virtual machine.

• 
  In Hyper-V Manager, click Action > New >
  Virtual Machine to bring up the New
  

Uhhhhhhhhh - this step obviously implies one knows

1) Where the Hyper-V Manager is

2) How to start the Hyper-V Manager

Isn't that odd ?

 

Moving Hyper-V to Another Disk

1. Export the virtual machines to the drive where you want to move them (tutorial).
2. When all VMs have been exported, delete them in Hyper-V Manager.
3. When Hyper-V Manager is empty, not showing any VMs, import the previously exported VMs (tutorial). In Option One Step 6 of the tutorial, you need to select Register the virtual machine in-place, or if choosing Option Two in tutorial, select Step 2.

Easy!
