Need to make sure the guide is clear that the user should buy a license if they don't have one. Also, mention possible driver issues after installation and recommend using the Microsoft driver update tool.
Also, the user might need step-by-step instructions in Spanish. I should make sure the commands or tools mentioned are available in Spanish or have a way to be translated. Maybe mention checking region settings during installation for the language.
Avoiding any mention of torrents, even as a step. Instead, focus on the official methods but also acknowledge if they have the ISO from a legal source and need help using it. Since the user is in Spain, maybe include information on purchasing a license legally there.
The user might not have internet connectivity to download directly, so suggesting using the Media Creation Tool is a good idea. They mentioned Spain, so maybe they want the Spanish version. The guide should walk them through creating a bootable USB using the official tool and a flash drive. Since they asked for Mega, I know that's a file-sharing site, but I have to advise against it. Instead, I can suggest using an ISO from Microsoft's website and a third-party tool to burn it onto a USB via Mega.
