Hi erpster96

You are right and i saw that today at 4.00 AM.
What i don't understand is why Microsoft send it to AMD users and all especially in my case for my dual 4 cores/6 cores Opteron servers like i have...

As far as i know there isn't code security patch update available yet or ready for...

I have been already forced to uninstall it at august end due to abnormal bugs and crash and BSOD
(Kernel security check failure) and again today as personal decision for several good reasons anyway.

Kinda weird that they send it for AMD computers with old CPUs as not listed anyway in their list of supported products...
This way, it may seriously impact os's stability by causing abnormal issues with kernel security check servicing/proceed.

Update from September 13, 2018...

The September version defeated overclocking on Broadwell-E, has anybody tested KB4100347 on the October 9th one? I am pretty sure I installed the October 9th one that day since I had also installed 17134.345

Again, if you install this KB for Broadwell-E 6xxxK/X chips will not overclock they will just adhere to ITBM 3.0 Boost Tables until the KB is uninstalled.

Haswell normal desktop does not seem affected for overclocking.

It's a less than ideal solution but if you rename the file mcupdate_GenuineIntel.dll in system 32 to mcupdate_GenuineIntel.dll.disabled you can prevent the microcode from running (make sure you are altering the file extension).

Any subsequent sfc /scannow or DISM online repair will mark this renamed file as corrupted, therefore if you happen to run these commands remember to rename the file again after the scan and repair operation completes.
