Objective of this article to share how to solve the problem of VirtualBox can not run when Hyper-V is installed in windows machines. This problem might occur when we try to run VirtualBox where already docker was installed. Because docker internally enables Hyper-V configuration in windows which will be the problem to run VirtualBox.

There are total 3 steps which we must follow to enable/disable Hyper-V in Windows 10.
- Search for Apps & Features in Windows Search option
- Search for Turn Windows features on or off
- Select/deselect the Hyper-V option from the popup opened to enable/disable accordingly.
For more detailed explanation continue with further article.
- Search for Apps & Features in Windows Search option: Look at the below image for more easiness to find Apps & Features option.

- Search for Turn Windows features on or off

- Select/Deselect the Hyper-V option from the popup opened: Deselect Hyper-V option and click on OK button to disable Hyper-V in your system. Since Hyper-V is OS level configuration, it will ask to restart the computer to make changes are affected.

We should restart the system to make affect of Hyper-V configuration changes. Afterwards, try to run the virtual box again. Hope it will run successfully without any failure.
