I got the same thing, said already installed and I did mine about 2 months ago.
One thing to note my microcode didn't increase in this update listing, so maybe that is issue but I would think it would just overwrite the file.

Yep thats the expected behavior I had.

The KB article was updated on April 5, but the msu file itself didn't change. You can see this by downloading it and opening it up in 7zip,

Hi JennyJ - many thanks did as you suggested and downloaded the KB - all went well and CPU microcode now shown as updated - many thanks again.

I installed it manually and this led up to me doing an Inplace Upgrade Repair.

What is an in place upgrade repair?

So they released a bios update for my Asus Maximus x code today. Only release notes were "updated cpu microcode". When someone checked into the bios file, they posted some of the microcode info and the only one with a recent date was "906ED" which is not on this particular windows update. I scrounged around for info and saw that is maybe comet lake? Maybe all just a coincidence?

I'm currently running an i7 8700K on an Asus Hero XI using bios 0602 which has uCode of 96. If I update the bios to the latest(0905) then that changes the uCode to 9A. Can anyone say what effect if any it could have on the CPU as Intel states 96 is the correct uCode for that chip. I assume the latest bios is for the 9 series of CPU's. KB4465065 is installed but does nothing to change the uCode back to 96.

Where are you reading your microcode from? So as I've learned after watching this thread a bit is that there are two ways to update microcode. One way is to get via bios update which writes the microcode to the board itself. The other is via the manual Windows update which places it in a dll file. If at startup, windows sees more current code in the system files vs the bios, it uses that microcode. So you could update the bios but always be seeing the windows update provided code, and also the opposite.

New update V3 9/4 Microsoft Update Catalog Not sure if it has something to do with Intel Microprocessor Memory Mapping Vulnerability Advisory - April 9 - Windows 10 Forums

O wait, it says 9/4 but downloading the same old file ??? is that normal?

it's the same V3 of KB4465065 that I downloaded back last month in March. it's only a "metadata" change with the MS Catalog site but the actual MSU file for that one (aka the binary download) has not
