    Is it possible to slipstream AV definitions into the Win 10 ISO image?


    Over the past few weeks I've put together a library of quite a few Windows 10 ISO images with various unattended setup configurations. I've also written a script that automates the whole process of adding the latest Windows updates to ALL my ISO images automatically. However, I have not figured out a way to integrate the latest Microsoft Malicious Software Removal Tool or the latest Antivirus Definitions.

    Does anyone know if it is possible to slipstream this into an ISO image?

    I know that these components are small and it's very easy to go online and just let them install automatically after installing Windows, but it would just be a nice finishing touch to slipstream these in along with the monthly Patch Tuesday updates.

    The Microsoft Malicious Software Removal Tool has to scan after install so it would be a waste trying to slipstream it and the definitions for it changes each month as well.

    If you do offline installs, you have to go this route.

    bro67,

    do you really think that I didn't do a google search first??? Besides, if you would take the time to actually read the question I posed, you would note that I DID NOT ask about Windows defender!

    I was specifically asking about the
    Microsoft Malicious Software Removal Tool and the latest virus definitions, not defender itself.

    Sorry if I sound little terse in this reply, but one of my pet peeves is when someone tells me I should have just googled something and then they proceed to point me to something I didn't even ask about

    You are being peevish - your post is very unclear and it is reasonable to assume you are talking about Defender!

    Apologies if what I was after was not clear. Apparently I must not have been clear since multiple persons were led to believe I was after Windows Defender.

    I was specifically asking about the
    Microsoft Malicious Software Removal Tool and the latest virus definitions, not defender itself. The malicious software removal tool is updated each month on patch Tuesday just as cumulative updates are, and the AV definition files get updated a lot more frequently than that. I already know how to manually download these for offline installation on other machines (as per the above links), I just wasn't clear on how to integrate them into a Windows ISO image.

    I'm still not sure why everyone thinks I was looking for Windows Defender when nowhere in my post did I ever refer to Windows defender, but I will try to be more clear in the future.

    Given the definition files in the link, the files are in \ProgramData\Microsoft\Windows Defender\Definition Updates\{825ADDC1-179E-4510-9F5B-A0893A0EC986}

    You will want to update the mounted image folder there after extracting mpam-fe.exe with 7-zip.

    These files are also in the WinSxS folder ( for /restorehealth purposes)

    Dunno about the Malicious tool thing tho'.. ...

    Hi folks
    Sorry to be perverse about this but I really just can't see the point.

    If you are doing off line installs presumably you don't need to worry about Viruses etc at that point anyway.

    After an offline install I'd imagine eventually you will want to connect to the internet and get updates -- at that time there could literally be 1000's of new definitions found since your ISO creation date and the date at which you connect to the internet. WD will then fetch the definitions and update.

    Cheers
