I have two Windows Server 2012 R2 Standard Edition Virtual Machines running on a Windows Server 2012 R2 Standard Edition with Hyper-V role. As a student, I've been playing around with the virtual machines and trying various modifications to test its performance. When I first installed it, both vms automatically validated themselves.
Now, I want to start from scratch by resetting both vms to factory default settings. How do I do it?
I ran the iso as primary boot and it only gave me the option to install it. I don't want to invalidate my windows license key.
