    instalI.wim install.wim in a ISO I downloaded from Microsoft


    Never seen this before. Downloaded a 18362.239 ISO from Microsoft by adding this useragent string for microsoft.com to Firefox:

    Name: general.useragent.override.microsoft.com
    Value: Mozilla/5.0 (iPhone; CPU iPhone OS 10_1_1 like Mac OS X) AppleWebKit/602.2.14 (KHTML, like Gecko) Version/10.0 Mobile/14B100 Safari/602.1

    Then when I went to the MS site I was taken directly to the ISO download page. When the download finished I got the instali.wim (i instead of l) which I have never seen before. Anyone know what the deal is with this or seen it before?

    So this is something others have seen? It doesn't install but comes up with a weird error message which I am sure is due to not finding install.wim.

    Edit: I can't reproduce it, tried a couple times.

    This has been a known technique for some time: it involves changing the "user agent" data that the browser presents to MS servers to be "something other" than IE or Edge. If you run this Google Search you'll find articles from WinHelpOnline, Winaero.com, HowToGeek, BleepingComputer, and many other players who explain how this works and how to do it.
    HTH,

    PS: AFAIK, this also gets you ISO files with .wim image files inside them, rather than .esd image files.

    Why would I have gotten this from Microsoft though? I downloaded the ISO 3 times over about 40 minutes and in each case got the instali.wim.

    Now when I try to reproduce this using the same exact process I can't.

    I solved my problem by using MCT to download the x64 and x86 versions and letting it create the USB flash for me but I'm still annoyed it happened, especially when I don't understand how it happened from a Microsoft server.

    I'm not going to waste any more time on it but it sure is strange.

    Certainly you don't believe that Microsoft is infallible, do you? Sounds like it was a mistake that got past their QC until it was discovered and then they corrected it.

    For example:
    Mars Probe Lost Due to Simple Math Error - Los Angeles Times

    @Ztruker,

    You know.....
    I'm Ready to Give Up Trying to Install

    I wonder? Same issue?

    Could be, but Microsoft?

    I think I still have the ISO at the shop. Anyone interested in looking at it? If so I can upload it to a file sharing site for a bit.

    Downloaded a 18362.239 ISO from Microsoft
    Right now downloaded from https://www.microsoft.com/en-us/soft...d/windows10ISO using iso downloader:

    Immediately after installation in VM (no problem with .wim file name), winver says:
    18362.30 (v1)
    18362.356 (v2)

    No way to get 18362.239 version ISO, furthermore corrupted. Weird.

    instalI.wim install.wim in a ISO I downloaded from Microsoft-v2.png

    --------------------------------------------------------------------

    EDIT: Tried firefox & changed useragent string for download: no change, same v2 ISO file, same hash.

    Then when I went to the MS site I was taken directly to the ISO download page.
    Very suspicious, never seen: some hijacker malware? It can be the culprit.

    I honestly believe, and I know this is hard to believe, that it was a simple mistake Microsoft had made internally, found it, and corrected it.

    Agree. It was only there for a few hours then gone.
