Need to install Windows 7 inside Amazon AWS

I have Amazon AWS with Windows server 2016. Now I need to install windows 7 inside of this. Is anyone here able to do this.
And you can check this video to clear my requirement. In this video he installed Windows 10. But I need Windows 7 with Minimum 8GB RAM.

Windows server 2016 has Windows 10 inside. You don't need to install it, it's part of the operating system.
I highly doubt that you can repackage it with Windows 7.
Have you already asked Microsoft about this?
