    That is not 21H2 as 2021 LTSC is and willl stay.

    When the upgrade doesn't offer you to keep all files and such:

    Anybody know where to download Windows 10 Enterprise Iot LTSC? The file linked at Massgrave and a few points earlier in this thread, entitled en-us_windows_10_iot_enterprise_ltsc_2021_x64_dvd_257ad90f.iso, is actually Windows 11 LTSC and displays Build # 26100.1742 rather than 19044.1288. I see there is an SVF(SFX) link to Windows 10 LTSC in these forums, so I guess I'll try that. Thanks in advance.

    I've been wrestling with Windows 10 Enterprise/IoT Enterprise (N) LTSC 2021 for a couple of days now and while I like the OS, it seems nearly impossible to install, unattended, I looked high and low for a working autounattend.xml file and consulted ChatGPT--nothing worked. First, the temporary *****-PDQGT KMS key floating around the internet doesn't work. Depending on how you initiate setup, it either asks you for a retail key or, sometimes, you can skip the key entry altogether and enter your license info after an install. The weird thing is I was able to install by downgrading from Windows 11 to Windows 10 Enterprise/IoT Enterprise (N) LTSC 2021 on my Intel laptop by clicking on the USB setup,exe file. But the same process would not work on my desktop AMD chipset, so I had to transfer my laptop LTSC OS image to my desktop PC because neither booting from the enterprise USB setup files or clicking on "setup.exe" within Windows worked for my desktop. Just wondering if others have encountered these issues.

    For skipping the key no need for autpunattended anything, just put this generic ei.cfg inside the ISO/USB:\Sources folder and all will be skipped:

    Code:
    [Channel]
    _Default
    [VL]
    0
    
    gVLK or retail passkeys can be found here:
    https://forums.mydigitallife.net/posts/1564663
    But no need for them when using the generic ei.cfg

    ps, why did you change the font size to 3, 4 is default and readable.

    @Enthousiast. Thanks. So no need for a autounattend,xml file? Regarding text size, fixed it.

    The IoT Enterprise KMS key will not work with the stock image, as KMS support was only added to IoT later.

    The shown ei.cfg will do the skipping of the key at initial setup, it is my preferred option to use.
