delete: remove VBox.log: The process cannot access the file because it is being used by another process.

Hi
It is great to use minukube. Thank you.
But looks like sometimes minikube is not able to delete cluster on Windows 10 with VirtualBox. I think potential cause can be slow work of VirtualBox: file with logs are still in use when minikube is trying to clean up resource in file system.
Please find detail below. All steps to reproduce in attached txt file.

The exact command to reproduce the issue:
minikube delete

The full output of the command that failed:
C:\Windows\system32>minikube delete
x Deleting "minikube" from virtualbox ...

! Failed to delete cluster: remove C:\Users\Anton.minikube\machines\minikube\minikube\Logs\VBox.log: The process cannot access the file because it is being used by another process.

• Sorry that minikube crashed. If this was unexpected, we would love to hear from you:

The output of the minikube logs command:
C:\Windows\system32>minikube logs

! api load: filestore: open C:\Users\Anton.minikube\machines\minikube\config.json: The system cannot find the file specified.

The operating system version:
Microsoft Windows [Version 10.0.17763.475]

This issue looks like #4137 but I don't know shweta9651's previous commands.

Oracle VirtualBox Version 5.2.8 r121009 (Qt5.6.2)

Removing or moving directory ~/.minikube/machines/minikube helps to return back to initial state of minikube, state after installation.

Interesting. I suspect than on Windows, you may need to run minikube stop before minikube delete. Do you mind testing this theory?

If that fixes it, we should just make that step automatic.

I have the same problem and tried this:

> minikube stop
*
X Unable to stop VM: open C:\Users\Csongor Halmai\.minikube\machines\minikube\config.json: The system cannot find the file specified.
*
* minikube is exiting due to an error. If the above message is not useful, open an issue:
  - https://github.com/kubernetes/minikube/issues/new/choose

and then

> minikube delete
* Removing C:\Users\Csongor Halmai\.minikube\machines\minikube ...
*
X Unable to remove machine directory: remove C:\Users\Csongor Halmai\.minikube\machines\minikube\minikube\Snapshots\0113C205-19E6-4E44-9903-D0AA9C750A39.vmcx: The process cannot access the file because it is being used by another process.
*
* minikube is exiting due to an error. If the above message is not useful, open an issue:
  - https://github.com/kubernetes/minikube/issues/new/choose

This seems to be show-stopper for me. :(

@halmai - I've moved your issue to #7300 - as it affects a different hypervisor
