    [2] is usually ESU, but [5] All works, too. You can check your activation again, it should include ESU now.

    Hello, I activated 1st, 2nd, 3rd and 4-6th commercial ESU using TSForge back in November 2023. Everything was working fine until yesterday, when the Windows Update stopped receiving updates.
    Now the Update&Security->WU shows big red "!", and says "You're not up to date" (this message was different a year ago without ESU).
    Below that is a red text "Your device is missing important security and quality fixes."
    Pausing button is grayed out.
    In the key HKCU\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\ConsumerESU there are still DWORD values:
    ESUEligibility = 1 and ESUEligibilityResult = 12
    But the key HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform\ESU contains 3 DWORDS:
    Win10CommercialAzureESUEligible = 0 (I think this is OK), Win10CommercialKeybasedESUEligible = 6 (this seems to be the problem) and win10ConsumerESUStatus = 1 (not sure about that). Putting value 1 instead of 6 in Eligible value and starting WU reverts it to 6.
    Looking at HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WaaSAssessment\Cache, UpToDateDays = -1, UpToDateImpact and UpToDateStatus are 3.
    All licenses checked with slmgr have status "Licensed" and are VOLUME_MAK channel but windows still refuses them.
    Running ClipESU.exe from elevated cmd gives:
    Code:
    MainHR start
    NOT Running on Azure Stack HCI or Azure Cloud and is not Azure Asset Tagged...
    Key-based ESU is enabled for at least one year...
    First and last line are green, the middle one is red.

    I've exhausted my humble knowledge about this but the intuition tells me M$ found a way to stop TSForge created ESUs.
    But then again, I'm quite surprised no one yet reported it anywhere. :confused:
    Can someone please look at this and give much appreciated advice, I hope I'm not the isolated case as it happened on 2 PCs.

    Thanks in advance.

    On what windows did you run that? Afaik, back then no windows 10, eligible for ESU, was ended officially.

    + TSForge was created in February 2025:thinking:

    Maybe some screenshots would make it more clear, or the exact copy of the txt in the command window, paste it here in code tags.

    Do I need to stop any services before merging the key?
    I already stopped windows update service and bits, then set 3 DWORD values in ...\WaaSAssessment\Cache of the form UpTo* to zero, started back the services and opened WU screen but it reverted to values to -1, 3, 3.

    Thanks in advance.

    EDIT:
    Windows 10 Pro. But in Nov 2025.

    Start with telling us what version of MAS you have used, show us the content of the cmd window it ran in and tell us exactly what the "tweaks" are you ran on the install.

    That looks like ESU was not enabled, and I would say is actually better than my case. You should check/post slmgr /dli and /dlv output to see the licensing status.

    Aww, what a nice looking image. I'm trying to understand what happened on my 2 PCs... I'm trying to understand how and why the fix is working.

    So I have to delete it completely and reconstruct a bare skeleton... changing just 3 values in subkey Cache that I mentioned in my previous post doesn't work.
    I was hoping to understand what went wrong but don't have a working system to compare with. Except VM installation but that is too much time consuming.

    That was just a remark - if it is forbidden, then just remove it or something.
    I still didn't find the time to try the fix as I'm having a hectic weekend but I'm pretty confident it would work. And as I said, I would also like to understand why a fix is working.
