    @Enthousiast integrated latest 1904x lcu for 2021 enterprise ltsc x64 nl with w10ui which has bypassesu, but enterprise ltsc doesn't need esu

    host os doesn't matter (back to 226x1 host then, because of 1904x acx-classextension incompatibility with panther lake) - update is broken for enterprise ltsc when integrating offline without bypass esu

    microsoft released latest 1904x lcu later than usual, so probably microsoft failed to fix that bug and released latest 1904x lcu with that bug anyway

    one bug signaled by a friend..Has anyone got the same or a solution??
    thanks

    This morning, proudly, I proceed to the monthly update, without worrying (never had any worries until now).
    Reboot and...

    Unfortunately, more sound after installing the October cumulative patch on W10 LTSC 2021.
    I tried everything (reinstalling the drivers of the video card, changing the DVI cable for an HDMI); nothing to do. What saved me is a restoration image disc last month, and for now, I have suspended the update while waiting to see on the internet the reactions (and I hope the solutions) of other users of W10 LTSC 2021 and KB5126657.
    The update of the other elements has gone well (NETs, for example). It is clearly the cumulative MàJ that is the cause.
    Did you have any problems? Good luck to all...

    Currently, I am connected to DVI. The sound is "driven" by my video card and the driver of it, an old Sapphire R9 270X OC (AMD) graphics card, with a pair of basic speakers plugged in by a 3.5 mm jack on the back of the screen. The last driver of the map dates from 2020, is obviously no longer updated.
    Everything worked nickel before the MàJ Windows this morning. W's diagnoses failed to fix the situation, nor the reinstallation of the driver of the video card that manages my sound, nor the exchange between DVI or HDMI. Only restoration to the previous state has been salutary at the moment.
    We are talking about an old config, computer of 2009 based on an Asus P6T LGA1366, an antique i7 950

    I had the same problem of no audio following the LTSC update on 1 of 3 computers. I uninstalled the update and all was well again. I later noticed that a different security KB had been installed but everything is working. No problems on the other 2 machines.

    I solved the sound problem with selected KB5126657 updates: there was in my case a simultaneous Logitech Audio Driver update which killed the audio presumably designed for equipment more modern than mine - the PC is from 2011 and the Logitech speaker setup from 2017. I blocked/hid the Logitech update and reinstalled the rest and everything has worked since then.:)

    Hello everyone, apologies if I’ve posted in the wrong section. I wanted to know if the UUP Dump website allows for the download of updated versions of Windows 10 LTSC 2021 (21H2, build 19044.7807 and later). I tried downloading and installing it on a virtual machine, but it doesn't seem to be the correct ISO. Thanks to anyone who can provide an answer.
