KB4090007 Intel Microcode Updates for Windows 10 v1709 - January 8

Hi,




Maybe so but then my machine was fully (softtware) patched when running 1709. It no longer is since upgrading to 17133 so something's not quite right.

Cheers,

I beg to differ. I updated from 16299.xxx which was patched to build 17115 and then !7XXX to 17131.1 and when I run that test for specter/meltdown, I get the same result as I did when I ran it in The FCU Build 16299.xxx. MSI is NOT going to update my X58-7522 BIOS so I am as updated on this issue as I ever was.

Hi,

Not sure what's going on but the original IP install which is now running 17133.1 is not protected against Spectre either.
This ssd sits in the same machine running two upgraded FCU installs that were fully protected but no longer are Spectre protected now.

This is a Kabylake which in fact should be protected but now no longer is.
Anyone else in the same boat ?

Cheers,

I am protected against Spectre but not meltdown.

Hi,



That's even more weird as the OS should bring Meltdown protection, the KB loading the MCU serves to mitigate Spectre....

Cheers,

The only way to get protection from Meltdown is with a BIOS update, or so I have been told. I have Legacy BIOS and MSI will not update it.

Hi,



Nope, that used to be so for Spectre. Now that MS has taken over from OEMs etc, MCUs will be loaded at boot by Windows as per KB4090007.
Thing is, that only works for OS version 1709, not 17133. And of course only covers Skylake, Kabylake and Koffeelake cpus so far.

Cheers,

Then please tell me when I was using The FCU Build 16299.XXX I was protected against Spectre and NOT Meltdown???? I am still protected in the same manner and I Do not have any covered CPU's as you can see in my Specs.
