Tutorials of solving Virtual Box & Activation Problems

Asked by Customers: I've installed Windows 10 in VirtualBox before upgrading to Windows 10 from 8.1 on my 2 PCs. How can I activate the clean install test copy of Windows 10 in the VM? I have a retail product code for Windows 8 but this doesnt work. I also don't want to affect the activation when I do upgrade my PCs. I could install Windows 8 in the VM using my retail key then upgrade the VM copy to Windows 10 - but what would happen when I upgrade my main PC since Microsoft would see two activation requests for the same key?
