Workaround for VirtualBox Hardening issue

	My machine was experience virtualbox hardening issue and was only able to stay on the 4.3.12. We have a solution to get around it to run the latest version of Virtual Box. I hope this will help others to get around it.

	1. Install the latest version of VirtualBox.
	2. Once installed, open Register Editor
	3. Nagivate to the following path HKLM\SYSTEM\CurrentControlSet\services\vboxdrv
	4. Change Start value to the number 3 (delay start)
	5. Reboot your HOST OS
	6. Before you start your Virtual Box for the first time after your HOST OS reboot/startup, run the following command line as administrator

	sc start vboxdrv
