Whenever Oracle releases updates for their best and free desktop virtualization software, VirtualBox, you must update the extension pack to get extra features on the guest virtual machine. If you use some of the advanced features such as USB 3.0/2.0, VirtualBox RDP and PXE boot for Intel cards inside a virtual machine on Windows 10 or 8.1 host, then you must update VirtualBox extension pack to the latest version. This small guide shows how to download and install the latest Oracle VM VirtualBox extension pack 6 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 particular virtual machine can’t be resumed without removing some of the settings or updating the extension pack.
If you want to start the virtual machine without installing the latest extension pack, you can simply disable USB2.0/30. 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 the following warning message.
