    After putting updates on my Windows images, I happen to see that the ISOs get buffed up real quick.

    So far, I've been using MSMG Toolkit to package my Windows installation to ISO.

    I want to know how I can manage the ISO size of the images.

    So where should I start? Cleaning out the updates that are past the current one, like the ones before the last update?

    EDIT: OK, let me ask another way: do I still need the updates left over from previous update sessions, say back in August 2023?

    It works like this, you install the latest update available then clean it with dism++, otherwise it does the job, you don't worry about which one it will remove, it does it automatically

    ISOs are useless since the Vista days, (in fresh install just deploy the WIM image, in in place upgrades you don't need the install media at all, just copy the installation folder somewhere and run the setup.exe

    That said is a good pratice to use resetbase the WIM to greatly reduce it's size (getting rid of the supersedes packages), if you're scared by DISM just use MSMG given you're familiar with it.
