  1. Update Failed Feature update to Windows 10, version 1903 - Error 0xc1420121


    Hi there.


    I've been having issues updating my Windows 10. Currently I'm on Version 1803 OS Build 17134.1130.


    Im having Error 0xc1420121


    Here is a screenshot of the error :


    Update Failed Feature update to Windows 10, version 1903 - Error 0xc1420121 78ba36aa-36a3-47f0-8521-cbef9a69727b?upload=true.jpg

    I have tried a couple of times installing while disabling my AV Malwarebytes, but it continues to fail. I also tried updating via the Media Creation Tool, but also fails. I tried deleting the Windows update folder C:\Windows\SoftwareDistribution\Download, re-download + re-install still with no success.


    At the moment I haven't found any discussions that can point me out through this issue.


    I've read somewhere in another post to upload my Logs. Here are the links to my logs:

    I would appreciate it if someone has insight on this.


    Thanks!

    :)
