    Windows 10 ISO updates from Microsoft Media Creation Tool


    Hi everyone,

    I'm new here but hope to stay a long time

    I have a question regarding the ISO files that get downloaded via the Media Creation Tool.

    If I were to have downloaded the 1803 ISO say in May of this year and then redownloaded it again today would the latest ISO image have all he latest patches and updates rolled-in?

    Or is the initial launch ISO hard-baked and doesn't change over its lifetime?

    I hope this makes sense (it does in my head, so fingers crossed).

    All the best,

    Moley

    It is the original ISO you have already downloaded. All updates will be on the next build (v1809?)

    Well, Microsoft does update the ISO file and the MCT usually once in between major build upgrades. But very seldom will the ISO file have all updates added to it. Just one week after it is released it will likely need a cumulative update.

    For 1803 the ISO made by the MCT has been updated once, initially it was for build 17134.1. Some time after June of this year it was update to the ISO for 17134.112.

    The ISO created by the MCT is for a fixed build, your May ISO would be 17134.1. During install the latest updates can optionally be downloaded to bring it up to the latest build. If you do not check for updates while installing/upgrading, then windows update will get the latest update after the install is completed.

    You may want to download the ISO for 17134.112, but it is not necessary. Both the original and the updated ISO will end up installing the current build once updates have been downloaded.

    It is hard-baked like you say, but there was an exception for 1803. The very first one was with the Insiders channel enabled. The second was OK.

    Ubuntu's* get a new ISO almost every day, with very little updates. Not* the case for Windows Ten. You must get the latest CU, adobe & others to be up-to-date.

    Take care,

    It's not the only exception. 1607 got its ISO updated half way through its supported life - and 1809 is definitely going to get an updated ISO if/when it is eventually re-released.

    It doesn't harm to download the first version of the build and do all the updates. It just takes more time.

    Hi again,

    Thank you all for taking the time to reply.

    I like to keep individual copies of all the version ISOs that get released and I had planned to start downloading them towards the end of their release cycle in the hope that it would contain all the updates "rolled-in" - but, sadly, I guess not.

    Thanks again everyone and enjoy the rest of your weekend.

    I was planning to download the ISO

    No, not all the updates rolled in - but the revised 17134.112 ISO for 1803 did at least have fixes for most of the significant bugs that 17134.1 started out with. In the end it doesn't really matter which ISO you use, it only takes one cumulative update to get you right up to date.
