The file used when creating a new virtual machine becomes the hard disk of that virtual machine. It cannot then be used to create another new virtual machine. Therefore, it is important to use a copy of the downloaded file, especially if you are planning to create several virtual machines.
Unzip the VHDX file and copy the file to a personal folder. Keep this file as your master copy for that software release.
Save a copy of the file and rename it.
Move the renamed file to the folder on the Hyper-V server used to store virtual machine disks. By default it is C:\Users\Public\Documents\Hyper-V\Virtual Hard Disks.
