Small archive containing a utility related to HP Manufacturing Programming Mode, the factory state in which protected settings such as serial number and product data can be written. The name calls it an MPM unlock tool; no supported models or version are listed. Technicians use such tools after a board replacement or BIOS reflash to re-enter system information. Test it on a machine where you hold a full backup of the flash chip, since changing manufacturing flags on modern HP business laptops can be hard to reverse.
