The Schneider Electric HMIYP6RUSW10CTO is a recovery USB stick for the Harmony P6 HMI range, preloaded with Windows 10 for restoring configured products. It's a maintenance accessory — the kind of thing you keep on the shelf for when a panel's OS gets corrupted and you need to reimage the unit without rebuilding the runtime from scratch.
Single unit in the package, USB stick form factor — plug it into the Harmony P6 panel's USB port and boot from it to trigger the recovery process. The Windows 10 environment is baked in, so no separate OS license or installation media is needed. This is strictly a recovery tool, not a runtime deployment key; it restores the factory image to a configured HMI that's gone soft.
