Windows Docker Fails to start- Unable to create "erroractionpreference" - Solution

Docker Desktop for Windows

I ran into this issue while installing Docker and could not find any pre-written guides to fixing it. I thought this might be a good place to post it.

Docker will fail to start up and throw an error - list “Erroractionpreference” - HyperV failed to connect.

If that happens, open Hyper-V Manager. Click “connect to server”, then “local computer.” If you get an error, follow these steps:

  1. Open “Window Security”

  2. Open “App & Browser control”

  3. Click “Exploit protection settings” at the bottom

  4. Switch to “Program settings” tab

  5. Locate “C:\WINDOWS\System32\vmcompute.exe” in the list and expand it

  6. Click “Edit”

  7. Scroll down to “Code flow guard (CFG)” and uncheck “Override system settings”

  8. Start vmcompute from powershell - net start vmcompute

Thanks to this post for outlining these steps.
I hope this helps somebody else out!
