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 :/ ).

Please let me know your opinions
