I am trying to install the new Windows 11 update from Windows Update, but I keep getting error 0xc1900101.

The installation starts, and after a couple restarts, it says:

" Attempting to recover installation "

" Undoing changes made to your computer "

And then I am greeted with error 0xc1900101 on Windows Update.

    Evening,

    I have again attempted to run Win 11, this time using the ISO download to a USB. Upon running setup it gets to around the 93% mark, the pc rebooting several times, then fails. The setup failure reports 0xC1900101 - 0X4000d. Looked up the code and received;

    Image<br><br>0xC1900101 - 0x4000D Usually, a Blue screen issue, caused by an incompatible driver.<br><br>There would be a file named setupmem.dmp in C:/$Windows.~bt\Sources\Rollback, which you can interpret using WinDBG to find the problematic driver.<br><br><br><br>(I have no idea what WinDBG is or how to inerpret using it).

    Cheers

    Richie

    Hey Richie, I can help you with that. Can you share the Setupmem.dmp file using Onedrive?

    Setupmem.dmp present in C:$Windows.~BT\Sources\Rollback

    These folders may be hidden, so you need to either show the hidden files or paste the path in the Run Dialog box.

    I did try to respond the other day, but clearly did not read this recommended article, because I found my post was subsequently removed.

    This link should identify my particular issue - https://1drv.ms/u/s!AvgtwC2s8rpggYES9ktfvc-WqQKcrw?e=IM4049

    Yes, we need a better answer than an error code. Why did the system generate the error code!!!

    What Known Issue are they fixing?

    The OP's issue goes back to June.

    Hi CK,

    That's a problem with this tread, most posters don't list their build number.

    We know this is a known issue updating Dev but can happen if they are trying to update from other builds.

    Problem is also that Paul gives no idea who he's

    responding to in 16 pages of posts.

    And yes, I do wish posters would give the build #

    they're on!!!

    https://blogs.windows.com/windows-insider/2021/11/17/announcing-windows-11-insider-preview-build-22504/

    In there

    Hello Paul,

    That known issue is referring to 22504 with 0xc1900101-0x4001c error and has nothing to do with the OP concern. The error code 0xc1900101 can be a generic error code with many reasons for update error. Advising someone that is going to be fixed is incorrect as this thread dates back to June, not current Dev build. Please reread the known issues again. There is a specific -0x4001c extension for that error for this build only for some devices (Not related).

    Regards,

    I don't understand the response but I'm using my unique user name in a genuine copy of the Operating System (W10Pro). See my other response below

    Health check says it's Ok and it's a Microsoft Surface Go only about 3 months old.

    I ran MS recommended checks to see Op system OK and got 100% OK.

    Mysteriously the update to W11 has now disappeared from my laptop update page (and I haven't updated it is still W10Pro). I can only assume it's been withdrawn for the cohort of m/c's my tablet fell into. It would be nice if MS was a little less secretive.........
