I ran sfc then dism from the command line as in MikeGale's post, then ran the troubleshooting gui > windows update (as admin). it cleared out update files and started from scratch. running windows update after that did not install kb2919355, but nor was it listed any more, so I assume it was no longer needed. haven't had the same trouble since.
Windows update KB2919355 fails to install - Error code 800F0922
Windows 8.1 Update for x64-based Systems (KB2919355)
Installation status: Failed
Error details: Code 800F0922
System got to 89% then said it couldn't complete the updates and that it would back out the updates. 15 minutes later, I'm back where I started.
Is it possible windows defender or other virus scanner blocked this update?

2014-08-17T14:51:55+00:00 This problem is caused by Microsoft setting updates to use the Active partition instead of the System partition to install to. To resolve this, make sure your system drive is set as the active partition.
This is just another in the long list of screw-ups by Microsoft. This only happens in Server 2012 and Windows 8. Makes you wonder, huh?

Step 1: Deaktivate automatic update: type "sc stop wuauserv" in cmd (open as admin), press enter
Step 2: Go to C:/Windows and rename the folder SoftwareDistribution to SoftwareDistributionBAK
Step 3: Reaktivate automatic update: type "sc start wuauserv" in cmd (open as admin), press enter
Step 4: Go to Windows Update in your settings and hit "check for updates now"
Step 5: restart and watch the updates install without problems :D
i hope this works for all of you. I tried a lot of different stuff, but this was by far the easiest (and only way) that worked! Good luck
