    So if I'm not wrong, there is no legitimate way to get the W10 ARM file anymore as of September 16, 2021?

    If I am, how do I find it?

    True - but Windows 11 is where you'll need to go if you want an ARM OS. MS isn't offering Windows 10 on ARM any more.

    You can still find build 21390 (the last Windows 10 build) on uupdump.net. I think you need a previous Windows 10 version to create an iso, though. What I don't know is if that previous version must be able to actually run on an M1. If that is not the case, you could download the Windows 10 iso that is still available to Insiders (I think it is build 19044) and create an 21390 iso with the download from uupdump.

    Hey Carlos, i am also using a MBP M1 and wanted to run Windows 10 - not Windows 11 in Parallels.
    Can you please give me exact information, how you received the correct files from UUPDump and what you did after downloading? I have tried and downloaded a few files but after i had them downloaded to my local disc on my Win10 64 Bit Office PC - i could not create an image. I am new to ARM and never downloaded files from UUPDump.
    Maybe you can give me some good advice or a link to Win10 (DE - German would be best, but EN is also fine) that ist working for me.
    Do i have to download the files and create the ISO file from an ARM based system or is my 64 Bit system in Office ok for the job?
    Thanks so much in advance for helping me
    Michael

    I wouldn't bother downloading Windows 10 files from uupdump.net. While you can still download files for the last Dev Channel build (21390), that build will expire at the end of the month. Since there are no Beta Channel, Release Preview Channel or Retail/OEM builds available that can run on an M1 Mac, Windows 10 on M1 is effectively dead.

    Thanks for your answer - i have no problem with downloading files from other sources than Microsoft Insider Pages - my problem is that i tried a lot of Win10 ARM files from uupdump.net in my x64 Maschine to download and build an ISO file but the script never succeded and no ISO was built.
    So are there any Images that can be used for a longer period than the end of the month?
    How do you handle Windows10 on Apple M1?
    Has anyone a working ISO or even vhdx file and can share it?

    Not for Windows 10. You will have to use Windows 11. I wrote a short explanation about building an iso for the current Retail/OEM build of Windows 11 here. Maybe it helps.

    No need to apologize, your English is fine.
    More importantly, your post means that build 21390 might not expire at the end of the month. I thought all Windows 10 builds I used were rs_prerelease which will definitely expire. Build 21390 as a co_release build might continue to work, though. The expiration notice only mentions rs_prerelease.
