You can often find older or archived versions of community ISOs by searching for "MPB Pure" on the Internet Archive .
Because these are community-made projects, they are typically hosted on file-sharing sites or developer forums rather than official storefronts:
Custom ISOs are modified by third parties. Use caution, as they may contain pre-installed software or have critical security features disabled to save space. Always scan the file for malware.
If you need a clean, safe installation, it is highly recommended to download the official Windows 10 ISO or Windows 11 ISO directly from Microsoft and use tools like Rufus to customize the installation yourself.
