How to make snapshot and roll back to later with Microsoft Edge test Virtual Machines?

Question

So Microsoft provides us with free VMs with different IE/Edge versions for 90 days. They have a disclaimer that says following:

Please note that these virtual machines expire after 90 days. We recommend setting a snapshot when you first install the virtual machine which you can roll back to later.

How does one do that? Lets assume I want to use Virtual Box as my VM provider.

Answer 1

Here is a guide.

Basically just right click on the VM and "take snapshot". You can roll back at any time by shutting down the VM, right click, and select restore.
