I interpreted it the opposite. Maybe someone can clarify. The question is why would there be a difference between Win7/8/10 - it's afterall the same WinNT kernel architecture and has the same HAL hardware abstraction layer, it's a matured software code base, so any fix should be possible on all supported versions in the same perfection.
