platform type 10 is Core Gen8 Amber Lake Y,this microcode couldn't boot up Core Gen7 Kaby Lake Y
It seems that your tool can't parse microcode files properly. Since revision 20190312, 06-8e-09 ucode file bundles microcode for both pf_mask 0x10 and 0xc0; the same is done for quite some time in other ucode files, like 06-26-01 or 06-1c-0a or many earlier ones.

Is there any Windows application could extract 0xc0 microcode from 06-8e-09 ucode file bundles? And it seems the microcode was updated C6,why only B4 there?
I find some microcode from herehttps://github.com/platomav/CPUMicrocodes/tree/master/Intel,Is this be the same as official code?
While it's unofficial, it tends to be the same; note, however, that it sources microcode files not only from official Intel microcode releases for Linux (here), but also from Microsoft and Apple updates (that tend to push them before the official releases without any meaningful notices and descriptions).
KBL-U/Y H0 6-8e-9/c0 when I inserting the CPU patch within MMtool,I'm notice something different from before: the version 8e 20180807 only 96KB,but version 4b 20190514 and 9a 20190312 are exceed 190KB; 4b and 9a platform type is 10 Instead of correct C0,and 9a update revision is 9E.
Why is that?![捕获](https://user-images.githubusercontent.com/44485578/64904293-7b481380-d6fa-11e9-9b8d-4db6d1675b00.PNG)
