In Windows 10 / Windows Server 2016 we have two, rather odd, new PowerShell cmdlets:
These cmdlets respectively remove and add the video adapter, mouse and keyboard from the virtual machine (note - they only work on a Generation 2 virtual machine).
At this point in time you might be wondering: "Why on earth would I want to do that?"
Well, in a large data center it is not unusual to find physical servers that are completely headless - with no video or keyboard. However, most people do not have these sorts of servers in their labs / offices for testing. Now you can use Hyper-V virtual machines to test how your software behaves when it is running on a truly headless computer.
