It appears to be included in KB4494441 for 1809 from the release notes below:

Cumulative Update KB4494441 Windows 10 v1809 Build 17763.503 - May 14

Improvements and fixes

This update includes quality improvements. Key changes include:

• Enables “Retpoline” by default if Spectre Variant 2 (CVE-2017-5715) is enabled. Make sure previous OS protections against the Spectre Variant 2 vulnerability are enabled using the registry settings described in the Windows Client and Windows Server articles. (These registry settings are enabled by default for Windows Client OS editions, but disabled by default for Windows Server OS editions). For more information about “Retpoline”, see Mitigating Spectre variant 2 with Retpoline on Windows.
• Provides protections against a new subclass of speculative execution side-channel vulnerabilities, known as Microarchitectural Data Sampling, for 64-Bit (x64) versions of Windows (CVE-2018-11091, CVE-2018-12126, CVE-2018-12127, CVE-2018-12130). Use the registry settings as described in the Windows Client and Windows Server articles. (These registry settings are enabled by default for Windows Client OS editions and Windows Server OS editions).

I already updated and still have revision 0x84. According to GitHub, the new release for my CPU should be 0xB4

According to other sites it should be KB4494174 -- 2019-05 Update for Windows 10 Version 1809 (Intel microcode updates)

But there is no reference in Microsoft site for KB4494174.

Nevertheless They have updated the date only for the old microcode

Yeah, I can't find anything for KB4494174 at Microsoft either. Hopefully soon.

It seems KB4465065 for v1809 got a recent WU metadata change this June:

Intel Microcode Update Juni 2019 fur Windows 10 1809, 1803, 1709, 1703 und darunter | Deskmodder.de

one of the screenshots there has the KB4465065 update being installed thru Windows Update - so this update is no longer a Catalog-only update



KB4494174 has not been released yet - maybe in late June or sometime in July

Thank you. It looks like the KB4465065 download has been updated for 6/11 using the same links, but I added a not in the article to help let folks know.

Microsoft hasn't updated the article yet since 4/5 though for any changes for the new 6/11 version.

My system received this KB (still labeled 2019-02) via WU auto update check this morning along with 3 others including CU KB4503327.

I tried to apply the MSU to my system, but got this error message:

As I use Dimitri's excellent handly little cpu-info.ps1 script, I see I'm running Microcode revision 0XC6 and my UEFI microcode revision is 0XC2. This raises an important question (for me, anyway): does this mean I'm OK and already caught up?
Please advise, and thanks,
