MAS scripts should be safe, but what about Windows iso you can download from MASSGRAVE website
I recently asked if MAS was save to activate windows, it turns out it was as I hoped.
However, I've one last doubt: I downloaded the iso from MASSGRAVE (it-it_windows_10_consumer_editions_version_22h2_updated_may_2024_x64_dvd_49ddadb6.iso) and I installed that already.
Also, I logged in my accounts and used sensible passwords already, should I be worried about this? (I ask because some pirates said the ISO should have been downloaded from Microsoft website :/ ).
You can always download the ISO from Microsoft's site. Just spoof your User Agent's OS to Linux and it will automatically redirect you to a Windows ISO download page.
Specifically the OS download links. If you're running Windows, it'll link you into the media creation tool instead however since this tool is a Windows Executable it'll not work on Linux by default, so they link to ISO files instead.
I downloaded them with this method "Win10_22H2_Italian_x64v1.iso" but the checksum is different, sadly. I don't know if it's a different version though, the file I have from massgrave is named "it-it_windows_10_consumer_editions_version_22h2_updated_may_2024_x64_dvd_49ddadb6.iso"
