This error may appear anytime a Windows Update fails. To investigate possible solutions, we need to start with the specific error code. We can do this by viewing your update history. Swipe in from the right edge of the screen (or, if you're using a mouse, pointing to the lower-right corner of the screen and moving the mouse pointer up), and tap or click Settings . Tap or click Change PC settings , and then Update and recovery . Tap or click View your update history . View failed update error code. Please post here with your error code, so that the Community can try to help guide you appropriately.

By comparing the Update History and the updates needing to be applied, I've found that they are the same. Update History indicates all were successfully installed. @IMDIDOC, in my case, the Update History shows multiple successful installs, but the 'Installed Updates' does not show KB2919355. When I successfully installed KB2919355 on another Win8.1 system, it would boot directly into Desktop and I had a 'Windows Store' icon in the taskbar. I am not seeing this othe Win8.1 system where KB2919355 is being rolled back during the mandatory restart.

@Robert, I didn't know Windows8 had diskpart! I ran diskpart from an admin command prompt. selected the ESP partition (300MB FAT32) and assigned drive letter S. I was able to access the S: drive from an admin command prompt - a dir showed 253MB free. I did the same for another recovery partition (400MB NTFS). This volume had 131MB free. I think this eliminates one possible cause of the KB2919355 install issue.

failed as before. said couldn't finish the update. no error code. no anything.

I am pretty sure that files were downloaded each time. Unless the content is changing on the host that seems absurd, especially for the big downloads. However, for all I know this particular code might be pretty innocuous. E.g. it could be WU saying "That's all for today." or some such. What is a "DM" anyway? Perhaps there is a clue back in the other codes for the same group... Indeed: "Download manager errors". So it might also be a communication error or a symptom of cache corruption, etc. Probably would be a good idea to do what Marek suggested in his postscript... http://answers.microsoft.com/en-us/windows/forum/windows8_1-windows_install/kb2919355-windows-81-update-fails-800f0092-and/4d4d23a3-695a-4bd4-b340-d2ce9c75919d?page=40 (bottom of page, Re: SoftwareDistribution folder )
