I know it doesn't help your problem, but I have disabled updates until this is sorted. At this stage you may need to roll back to an earlier version of Windows.

I posted this in another thread, but it seems the update only limits the cpu core multiplier to defaults. So to get around this, I increased my BCLK to 125 and now my OC works. For my 6900k, it seems any multiplier over 37 won't work in Windows. But I increased BCLK to 125 and lower my multiplier to 35 to get a 4.375 OC.

Not everyone want to overclock BCLK though.

I think us ASUS X99 owners are out of luck on this one. Just make sure to block the update as long as you can

It limits overclocking on Broadwell-E processors. That and X99 boards. Not all though.

The culprit security patch that causes this issue as far as I've been able to ascertain is KB4100347 as in the OP, which contains the updated microcode. This will be loading the microcode at OS handoff, removing it should default back to the microcode contained in the UEFI firmware.

Don't have an X99 system set up here to try this, but my first step would be to uninstall the update.

This microcode patch is integrated in october 2018 update and can't delete separately or if can somebody come here to tell us!!!!!
I never installed those kb4100347 update myself. My overclocks working fine before this october update.

You can change mcupdate_GenuineIntel.dll with a previous version. Which you can find in "C:\Windows\System32". To change that file you need to take the ownership of the file from security settings. This will revert kb4100347 update and its side effect.
