    Hi all! I had the same problem installing Windows Update KB4093105. I tried both Windows Update download/install and the standalone installer from the Windows Update Catalog. Both failed with error code 0x800f0922.

    Microsoft is aware of the problems we’re having and is supposed to be working on a fix…well, at least for the Mixed Reality crowd…

    Scroll to the bottom of the page and there’s the official notice.

      Yup seems to be an issue with some users randomly. I’m still monitoring people having problems with installation of this update.
      One of my systems also got this issue but I was able to install the update manually.
