Hyper-V: Unable To Start a Virtual Machine From Downloaded ISO File

I’ve been working on a build of my new lab stand. I will use this lab to record some video that MANY of you asked me to do thousands of times (it’ll be a big surprise to all of you… for now, I just tell you that the environment I’ve been building contains 3 forests and 3 different versions of Exchange… )

The solution to this problem is VERY simple, just make a copy of the ISO file and then mount the copy instead. That it!
