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"
I've done quite a of setup already so it'd be annoying, even changing password is. I'll see what I can do next month as I'm to buys the next weekdays and weekends
You can check the md5 hash checksum provided by Microsoft to verify the authenticity. Massgrave gets it from Microsoft, it's a legit ISO just rehosted.
If you’re truly worried, change passwords and reinstall from the official ISO from Microsoft now. Do it now before the paranoia gets to you in a few weeks/months/however long and you throw out all the work you did in that time. I personally don’t think you’ve got much to worry about (were the checksums the same from both sources?) but I don’t know what your paranoia level is. Doesn’t sound like you’ve done a bunch of setup yet so reinstalling wouldn’t take long; might as well do it now rather than later is my reasoning.
