    Noobie question: do I need to sign in Windows Insider Program (Settings app) before upgrading with an Insider Preview ISO? In my desktop I signed in and then performed an in-place upgrade using a build 19043.867 ISO. Signing in Windows Insider just makes preview builds available for download through Windows Update, instead of having to download the ISOs and install them?

    I've examined your posts and your observations are interesting. The shared mistakes between MVS and UUP ISOs combined with identical file comparisons have lead you to believe that there is very little difference between the MVS and UUP ISOs. That would would lead me to think that converted ESDs and Techbench ISOs might be better? :thinking:

    my observations might totally miss the mark, does not change anything
    iso's released by microsoft remain the preferred install media for the simple fact that you can check beforehand for corruption via known hashes
    other than that, it makes little difference if you use mvs / techbench / mct / esd2iso / uupdump - all source files come from microsoft

    better?
    guess that would be using sfv diff files to update mvs iso's from one release to another, with minimal download size and processing, and verifiable hashes
    the only inconvenient is watching for the right language svf to be made available by the fine folks here at mdl

    then, to each one's needs.
    - no secret I'm a fan of the mct (in-place) upgrade-repair route and then do updates online. whenever I get a call about helping with broken lcu updates in 10, or nagging with 7, I just direct people to download the mediacreationtool.bat script, rename it auto mediacreationtool.bat and the just run it and sit back until windows is back at desktop. usually successful (quite many people went the posready route for updates convenience, and mct don't like that, but I've already made an workaround)
    - specific editions mix and integrated updates? early releases? any past-release specific-build? uup-dump all the way
    - wim editing? mvs / techbench
    - gargantuan all-in-one project? esd2iso and similar scripts

    ESD = formerly used by WU/WSUS and MCT, now WSUS and MCT only :biggrin:

    It is preview which means "optional" under the old terminology and not the recommended release.
    Anything released outside of the second Tuesday of the month schedule (with very few exceptions) is not recommended for regular use.

    Yes but, especially this build. Does it contain some kind of unstability or BSOD?

    Actually, there's literally no such thing as "not recommended for regular use." when these updates are in fact fully tested, and supported by Microsoft.

    They're not Insider Preview updates, and they're simply for you (not Microsoft) to test these changes more earlier which will then roll into the next Patch Tuesday update, and are completely optional.

    Whatever you get from Patch Tuesday, are more or less the exact same changes coming from those "Preview" updates. I get it that the word "Preview" is slightly misleading here for some people, but I'm not one of those people here that are responsible for what marketing names Microsoft should choose.

    I'm sure Thomas Hounsell would love your fantasy and conspiracy theories.

    They are optional for a reason. Like the .NET Framework updates released outside of the patch Tuesday.

    Those always just install on my systems, not optional.

    If one examines the Windows 10 Pro Index for all the 19042.631 ISOs, the Directory Number and File Number is exactly the same for every 19042.631 ISO. Media Creation Tool (MCT), Techbench, Windows ISO Downloader, ESD > ISO, and Microsoft Visual Studio (MVS) ISOs all have the following structure for Windows 10 Pro:

    Directories=24132
    Files=96477

    Since the version and build are the same (19042.631), the edition (Windows 10 Pro) is the same, and the architecture (x64) is the same, I think it's safe to say that these are all very similar ISOs.

    ISO size (in bytes) may vary and SHA256 hash may vary, but the ISO structure is the same.

    UUP ISOs were not included in this study because they are custom, homebrew, a waste of my time.

    Media Creation Tool (MCT) = Techbench = Windows ISO Downloader
    v19042.631
    Windows Pro Structure:
    Directories : 24132
    Files : 96477
    ISO Size=6,221,846,528 Bytes
    SHA256=6c6856405dbc7674eda21bc5f7094f5a18af5c9bacc67ed111e8f53f02e7d13d

    Microsoft Visual Studio (MVS)
    v19042.631
    Windows Pro Structure:
    Directories : 24132
    Files : 96477
    ISO Size=6,015,029,248 Bytes
    SHA256=fe029f3d94ffc3550312bfac48eaa01a87946a0792f8e34196a6252065e2c5fb

    ESD>ISO
    v19042.631
    Windows Pro Structure:
    Directories : 24132
    Files : 96477
    ISO Size=Varies depending on conversion tools (ESD>ISO, NTLite, DISM++, etc.)
    SHA256=Varies

    All of those are the same, why comparing them, only content of ESD and ISO differs at the available SKUs.

    UUP is the one to investigate and to be compared to all others, it contains less fod's then the others and has a self constructed boot.wim.

    The ISO of the ESD>ISO conversion is considered homebrew too, same as with UUP>ISO.

    Your ignorance about telemetry in W10 truly amazes me.

    For me, UUP dump is worth the time, because of the ease of use. As for the time taken, I just leave it unattended for an hour or so ;)
    The thing I like most about UUP dump is its ability to add virtual editions.
