    hi
    I discovered this forum via a google search
    can you do me a favor? can you download windows 10 latest version from ms website and let me know its checksums? I want to see if they are customizing it for each ip or if everybody who downloads it gets the exact same thing.

    The officially released MS ISOs from their download page are always the same and have verifiable checksums. However, they are fairly big as they contain the badly compressed install.wim. These are the only ones allowed to post here.

    On the contrary, ISOs downloaded using their MCT tool have better compressed install.esd, but are all unique, due to varying timestamps.

    "from their download page"
    what download page? I was under the impression that without MCT tool, you cannot download direct from ms website.

    There is nor such thing as badly compressed images here. ESD are solid archives compressed with the LZMS algo. .WIM are non solid archives, they obviously have a weaker compress ratio (using the LZX compression).

    They serve different purposes, WIMs can be mounted, edited, can have a single file replaced, can be booted directly and so on.

    ESD are good just when't saving space/bandwidth is the main concern. I never use them, so I'm not sure if the limit is still applicable, but once ESD ISOs were good just for fresh installations not for refreshes/in place upgrades.

    He ment badly "prepared for compressing" images

    sometimes they include different winre.wim across install.wim images (i.e. more size)
    https://forums.mydigitallife.net/posts/1361063/

    sometimes they forget to rebuild boot.wim or install.wim (i.e. more size)
    https://forums.mydigitallife.net/posts/1760898/

    sometimes they don't run dism cleanup for install.wim

    first or two Win10 20H2 ISOs were hot mess

    No, he specifically mentioned wim v.s. esd and I replied to that.

    Then yes, unprepared images are a thing (say server 2012r2 upd3 is 2GB larger than it should because isn't resetbased), but bad badly prepared images are so, no matter if they are compressed or not, no matter the compression method.

    The install.wim is badly compressed, compared to install.esd. The ISOs are servicable, but larger than they need to be.
    I'm still an avid CD/DVD user and this is important to me.

    Matter of semantic. But again there is no "bad" compression (unless you use a buggy compressor). LZX average compression ratio is usually between 2x and 3x (which is anything but "bad")

    There are just different tradeoff between speed - compression ratio - symmetricity (the ratio between the power needed to compress and decompress) and features.

    The ESD format an the LZMS it uses by default trade almost all features/flexibility and speed for maximum compression. Personally I found it trades too much.

    I'm sorry but what "being a CD/DVD user" has to do with the ESD v.s. WIM debate?

    I mean if I google "download windows 10" and click on the first link, it's a microsoft page that tells me to download media creation tool. nowhere on that page is there a link that i can click on which would start downloading windows 10 iso

    Hello,
    thanks for that, I needed 64 bit US English. but when I go to that website all I see is media creation tool. I don't now where you are seeing these links. And there is no point in me using those links since I already have the iso. what I am wondering is if the iso is unique to me (the paranoid part of me tells me they customize iso based on your ip or device or something about you to track you) or if they give everybody the same exact iso. hence why I asked for checksums from several people so we can all compare.

    Simple. Using install.esd, the ISO fits on the DVD, and using install.wim, it does not.

    Ah got it, you're talking of physical media, not just ISOs.

    The last time I used one was 15 years ago. The last time I used a ISO to do a *fresh* install was at least a decade ago.

    The only meaningful use of the ISO in the last decade are in place upgrades and given, since Vista, in place upgrades are possible only from a booted OS, having a physical media for that is not relevant.

    each month there is a new checksum because monthly update (which bump suffix build version 19041.xxxx) is integrated/slipstreamed from the 2004/20h1 (19041.~1) base released in May 2020.
    Microsoft refresh their iso at the end of the month.
    but you can do it yourself at the tuesday patch.
    Occasionnal user can install their Windows 10 with the May 2020 then Windows Update will install current version immediatly then next week the June 2023 build ...
    May 2020 or May 2023 doesn't change anything, except of course for IT guys which want gain some minutes to deploy their systems in mass.

    Then you didn't download the latest available ISO, it was not a genuine MSFT released ISO or it was corrupted.
