Windows 10: Cannot connect to Hyper-V after upgrade to 1809

I upgraded my W10 machine to 1809 (just before the fiasco forcing MS to stop delivery). My documents are intact, but what I found – Hyper-V on the machine cannot be connected anymore.

When I started Hyper-V MMC it did not connect to the local machine automatically and when I tried to force it I received and error:

“An error occurred while attempting to connect to server “xxx”. Check that the Virtual Machine Management service is running and that you are authorized to connect to the server.”

After some googling I found a solution from Anders Hanson which worked for me:

1. Open “Window Security”

2. Open “App & Browser control”

3. Click “Exploit protection settings” at the bottom

4. Switch to “Program settings” tab

5. Press “+” sign to add an exact path to a file or 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”

here is the original trail
