Windows 10: (Intel Microcode-)Updates (May 20, 2020)

[German]On May 20, 2020, Microsoft has updated another batch of microcode updates for Windows 10 version 1507 to 1909 (but these are probably old updates that were already updated in February 2020 as well).


Blog reader Hans informed me by email that he got KB4497165 offered by Windows Update on Windows 10. This comment also mentions the microcode update. 

Yesterday evening/today I got a Windows Update KB4497165
Strangely enough described with "2020-01(!) Update for Windows 10 1909 for x64-based systems (KB4497165)".

Quickly installed; reboot required. I guess now officially released firmware update.

According to the link Update KB4497165 "KB4497165: Microcode updates from Intel" (Last Edit in February)

However, this did not only happen with old notebook (i7-2xxx) and NUC (i3-5xxx) but also with the AMD Ryzen (2xxx)…

A further mention can be found in this German comment thread. In all messages only the microcode update KB4497165 for Windows 10 version 190x is mentioned. However, all still supported Windows 10 versions should have received updated versions of the microcode updates.

The list of microcode updates

Microsoft documents the microcode updates for Windows 10 on this page (which has the revision date April 6, 2020). The updates apply to Intel CPUs from the following series: Denverton, Sandy Bridge, Sandy Bridge E, EP, Valley View, and Whiskey Lake U. Only on these CPUs should the microcode updates be installed. Here is a short overview with links to the KB articles:

  • KB4497165: Windows Server Version 1903, Windows 10 Version 1903, Windows Server Version 1909, Windows 10 Version 1909
  • KB4494174: Windows Server Version 1809, Windows 10 Version 1809
  • KB4494452: Windows 10 Version 1709
  • KB4494453: Windows 10 Version 1703
  • KB4494175: Windows Server 2016, Windows 10 Version 1607
  • KB4494454: Windows 10 1507 (LTSC)

A quick check of the KB articles from the above list shows that the support articles have not yet been updated – so what has changed remains unclear. The download links for the updates can be found in the respective KB articles. My advice would be to wait and see if the microcode updates are offered for installation via Windows Update.

    Se supone que es una actulizacion para procesadores intel, pero yo tengo un AMD A9-9425 y me llego la actualizacion
    Alguien sabe si puede causarme problemas?

      También me dijeron que no lo instalaría, pero si ya está en él, no importa.

      That has been reported from other German blog readers. I wouldn't install this update – but it doesn't matter, if it has been installed already.

    "so what has changed remains unclear"

    the only thing that has changed is the windows update "metadata" for KB4497165

    and woody has noted that this KB4497165 intel microcode update has also been pushed to machines with AMD processors:

    My client reported that after this update his Lenovo T460's (with Intel i7-6700HQ processor) battery doesn't last as long as before.
    Has anybody else experienced similar issue?

    buongiorno, io dopo aver fatto questo aggiornamento tutti gli altri aggiornamenti non si installano…questa cosa è già successa su due pc…non so cosa fare!!

    good morning, I after doing this update all the other updates do not install … this thing has already happened on two PCs … I do not know what to do!!

  6. Bill says:

    Just got this update pushed today. I have an AMD 2K series and I don't understand why I need to install this. Anyone have any experience with theyr AMD machines after installing this? I'll try to stop this update until MS does release an explanation or the community digs deeper.

      I wrote on another post (maybe within my German blog): During boot Windows detects the CPU – and if it's an AMD, no Intel Microcode Update is loaded. So it doesn't harm, but it also doesn't help – just fill your disk.
