KB4090007 Intel Microcode Updates for Windows 10 v1709 - May 22

The list of processors that KB4090007 covers does NOT include this chipset...
FYI - this is my result from the Spectre & Meltdown Vulnerability checker Ver 8.0 WITHOUT KB4090007 installed.which says there IS a microcode update available!
Click to expand...

Mine says that too, even with KB4090007 installed...

...but neither my OEM through a bios update or MS through KB4090007 can be bothered to issue Intel's updated microcode *Banghead
