Couple of issues with this, the first being a "rudimentarily activated using a Generic Key" ISO that's not from Microsoft. Can you really trust this source and technically at this point, it's piracy. Secondly, once the Microsoft lawyer's get wind of this, expect it to be shut down rather quickly.
I'm okay with providing documentation, tools and scripts to remove the cruft and increase privacy within Windows 10, but the ISO linked from a Telegram channel is dubious at best.
