Saying this in a slightly better way...
You are looking at an 8th generation processor. Intel supports only Windows 10 on 7th generation and newer processors and corresponding chipsets. Intel develops and maintains device drivers for only Windows 10 on these processors and corresponding chipsets. While some driver packages can be used with previous versions of Windows, Intel is not validating these packages on these previous versions and thus no performance or operational guarantees are provided.
Hope this explains it,
