    I have an i7 8700k. I dont see this update installed in my list. Am I ok to use this update and install manually? Dont want to brick anything.... sisoft sandra is telling me I have a CPU microcode update and Im not smart enough to try and track microcode down and update manually....scares me.

    Also, when I try to run that powershell script (referenced here) and enter the below command i get the "term is not recognized" so Im a little confused on using that tool.

    .\CPU-info.ps1

    edit ok nevermind Im dense and it took a minute:
    I get that output to say my CPU microcode is 0x0F, which is not the "0x96" listed in the processors the update applies to. Should I use this update manually then? Sorry Im just extra cautious dont want to brick something due to my own ignorance.

    First things first. Being extra cautious when you have to deal with complicated issues, involving hardware, is more than recommended.

    Now, since you have a recent CPU, your best bet is to go to the Asus Support page and look for an updated BIOS. If there is one available, (I would guess that there must be one) download and install it. If not, download the KB4465065 from the Microsoft Update Catalog and apply it, manually.
    What you should have in mind though is, that is generally preferable to get the latest microcode via a BIOS/UEFI update and if that is not possible, then go with the Microsoft provided microcode update.

    For more info on the issue, check the section "Mitigate the vulnerabilities" in the following thread:

    Enable Retpoline to mitigate Spectre variant 2 (CVE-2017-5715) Solved - Windows 10 Forums

    UPDATE:
    Check if this applies to your system:
    ROG MAXIMUS X CODE CPU Support | Motherboards | ASUS USA

    Install the update. It is always recommended to update, and your CPU is most certainly included.

    Don't rely on the bios update it will take time, that is why Microsoft releases a software microcode.

    If your CPU is not support the update installer you inform you, it did happen to some users.

    The update will update the file mcupdate_GenuineIntel.dll which include the microcode for all Intel processors including yours.

    Even if it has the same revision, it could have security update, so update it.

    Yes I do have a new bios out there actually but I'm extremely hesitant 1) chances are it's going to mess with my overclock and 2)I really don't want to have to put all the settings back in manually. If the bios ain't broke.....I am very hesitant to fix. That's why I figured this windows update for the microcode was a good middle ground?

    Good info. So for some reason *if* the update caused issues, it could easily just be removed, because microcode via windows update is different that microcode actually written to the motherboard via bios update?

    I ran the script in another thread to see what Spectre mitigations were active and they all were apparently ok. Inspectre also confirmed. Except for the one "ssb" one that a lot of people have apparently show as false.

    You can always uninstall the updates, but in this case you don't need to,

    You are already using Microsoft microcode mcupdate_GenuineIntel.dll and this is just an update for the file.

    You can check the file before and after the installation it is in the folder system32.

    Don't worry, it is an update for a file you are already using, there will be no errors.

    Ok very good. Appreciative of the help.

    Just curious, is there any increase to startup time or other lag when you system is getting the more current microcode from windows versus having it loaded to the board itself already i.e. from a bios flash? Or is it still only as fast/slow as the microcode may inherently permit (due to whatever performance optimizations it may have)

    Nope, no improvements, it is most likely security updates, fixes for vulnerabilities.

    In fact if anything, it may make your PC slower, not noticeable to you, but you should update to protect against attacks.

    Yet, it may have performance improvements, you don't know.
