Whenever Oracle releases updates for their best and free desktop virtualization software, VirtualBox, you must update the extension pack to get extra features on guest virtual machine. If you are the person using some of the advanced features such as USB 3.0/2.0, VirtualBox RDP and PXE boot for Intel cards inside virtual machine on Windows 10 or 8.1 host, then you must update VirtualBox extension pack to latest version. This small guide shows how to download and install latest Oracle VM VirtualBox extension pack 5.0 and later versions on Windows 8.1/7 and Windows 10 host machines.
We have earlier published few guides on installing VB guest additions on Windows 10 and how you can use VirtualBox to install and test Windows 2012 R2 server at your home PC. Normally if you open a saved or new virtual machine without updating the extension pack, you will get an error message informing about USB2.0/USB3.0 and extension pack issue. The virtual machine can’t be resumed without removing some of the settings or updating to latest version of extension pack.
If you want to start the virtual machine without installing latest extension pack, you can simply disable USB2.0 support under VM settings as below.
As shown below, if you select USB 2.0 or 3.0 support without having the latest extension pack, you will get following warning message.

You can Install Extension Pack in Two Ways
1) Download the file from above link. It would be in ‘vbox-extpack’ file extension format in Windows 10/8.1. Once you open the file, VirtualBox would open and ask for installation. Click install to start the installation on Windows 10, it will be updated automatically if you have the previous version.
2) The second way is by going to File –> Preferences in menu, then select Extensions option in VirtualBox console. From here you can browse the downloaded extension pack and install it on Windows 10.
This installation will fix the warning message of USB 2.0/3.0 support on Oracle VirtualBox and now you should be able to start new or saved virtual machines. Another few additional features will be available now. USB 3.0 will allow your guest virtual machines to access the data in faster mode from the attached physical USB drives/Disks.
Extension pack installation is very important to run Mac OS X in VirtualBox as guest machine.
