These instructions offer assistance with enabling/disabling Hyper V in Windows 10. I have found it necessary to disable this service for use with Virtaul Box, then re-enabling it for Docker.

To disable Hyper V in Windows 10 (e.g. for use with Virtual Box):

1. Ensure virtualisation is supported by your CPU and enabled in the BIOS

2. Disable Hyper V for Virtual Box: https://docs.microsoft.com/en-us/troubleshoot/windows-client/application-management/virtualization-apps-not-work-with-hyper-v

3. Disable HyperV in Windows Add/Remove Features

4. And run this in PowerShell with Admin privellages:

   bcdedit /set hypervisorlaunchtype off
   

5. Restart PC

To re-enable Hyper V in Windows 10 (e.g. for use with Docker):

1. Ensure virtualisation is supported by your CPU and enabled in the BIOS
2. Enable HyperV in Windows Add/Remove Features
3. And in Power Shell, with Admin privellages:

   1. bcdedit /set hypervisorlaunchtype auto
      

   2. Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All
      

4. Restart PC
