    I have installed 28000.2179 on 2 machines, one X64 and one ARM64, without issues
    Installed with an UUPdump ISO of 28000.1719 and then updated
    Probably the ISO is butchered

    Difference here is: UUP dump ISO is 28000.1 + updates which are locally integrated by UUP>ISO conversion, MVS ISO is updates pre-integrated by MSFT.

    that was fast

    so 28100 is for retail release and 28120 as Beta / whatever

    Could someone share those files from May 2026 MVS ISOs?
    Code:
    iso:
    \efi\microsoft\boot\boot.stl
    \efi\microsoft\boot\boot.pnd.stl (if exist)
    
    install.wim:
    \Windows\Boot\EFI\boot.stl
    \Windows\Boot\EFI\boot.pnd.stl

    False.

    it reduces time domain frequency scaling so the peak clock is reached faster, the same boost level is achieved before and after, just at a reduced scale period.

    if the latest secureboot DBX is applied, you cannot install with older media signed with only the 2011 db.

    got the infamous new Start menu after installing this LCU, it's ugly and non-functional
    I haven't had any faith in Windows for a long time, but they just keep getting worse
    time is wasted on sorting out shortcuts

    Finally, after ~4-5 yrs, the white flash while opening a new TAB in FE, fixed with this 28000.2340 update.

    I'm looking for these files mentioned in microsoft learn under the
    windows_workload_hera.iso under the following section

    26H1 RTM AI Model Installation Guidance of a microsoft learn article

    Anyone knows?

    I would like to add this to my install.wim that already has all my sccm drivers.
