    The "MPB Pure" Distinction

    The "MPB Pure" designation signifies that this is not a standard, out-of-the-box installation from Microsoft. MPB (often associated with "Minimum/Pure Build" communities) releases are modified ISOs. The goal of a "Pure" edition is distinct from a "Lite" or "Gamer" edition. While "Lite" editions might strip the OS down to the point of breaking functionality, "Pure" editions aim to keep the core integrity of the system intact while removing unnecessary redundancies.
