KB4100347 Intel microcode updates for Windows 10 v1803 - January 8 Win Update

goopy · 03 Sep 2018

Greetings.
One of my two identical skylake systems has been updated with the KB4100437 when it was first offered. Should I do the same with the second? Or should I uninstall it from the first?
Many thanks and best regards,

I would worry about something more deserving of your time. When those of us who understand the issue get Microsoft to coordinate the effort it will happen correctly and with no user intervention.

Hi,
I personally haven't been offered any of these micro code updates I'm on a very old bios on x99 2101 not going to update it seeing asus cranked the vccio cpu 1.05 voltage well past safe levels which has been said by many as 1.15v and asus cranks it to 1.25v. just for increasing ram speed past 2133 lol :)

Odd, it showed up when I manually checked for updates today. Rebooting now.

KB4100347 has been installed twice now on both my PC's and I have the latest BIOS for both, so the system should ignore it :)

BIOS/UEFI microcode revision : 0x25
Current microcode revision : 0x25

Desktop:
CPUID : 000906E9

Yeap!!! Don't bother with it.

You can also run Speculation Control Validation PowerShell Script to see where you currently stand, with the existing Spectre variants

Puzzles me as to why they are updating machines that probably get OEM support.

My guess would be, that they don't check the current microcode before they offer the update, but after it is installed. The reason is either poor design or easier implementation - don't know!
