VirtualBox is very lent in Windows 10

[ForumBot]

I had VirtualBox installed on Windows 8.1 and it was working correctly. J'ai mis à jour to Windows 10 and re-installed VirtualBox, but it's very slow.

System Info:

- CPU : Intel Core i5

- Graphic Card : Nvidia 740m

- 6 Gigabyte RAM

- 256 GB SSD Storage

Drivers are à jour. 3D Acceleration is enabled.

Quel est le problem?

Dans mon cas, it was because Hyper-V was enabled. I had it disabled in Windows Features but I was still getting the turtle icon in the bottom right of the VirtualBox guest window. To turn it off completely, I had to:

- On the host computer, open Ligne de commande (as Administrator).

- Enter la commande suivante:
`bcdedit /set hypervisorlaunchtype off`

- Restart the host computer.

After this, there was no lag at all.
