KB2919355 (Windows 8.1 Update) Fails (800f0092 and 80073712) on Windows 8.1 Pro w Media Center

Corruption is an interesting issue.  AV and other software that touches the OS so intimately (like ExamSoft) needs to be tested prior to release of the patch. Its different when something is downloaded (some of the responsibility rests with the downloader).

But when dispensed by Windows Update, and they ask us to auto-update, then it seems the mechanism should have a list of tested software, and at a minimum, warn you your config was or was not part of the test matrix.

i tried many times downloading kb2919355 but i cant able to download beyond 92%. what is problem?

I too have had this problem attempting to run KB2919355 on my ASUS P1801 AiO.

The update gets to 99%, fails and then undoes all changes made by the patch attempt. I have tried eliminating all other programs running at startup except the commercial copy of the Emsisoft Online Armor personal firewall. Four attempts have been made to no avail.

The DISM command that you (Susan) suggested to run did not seem to work - I did run it elevated (right-click on tile then Run as Administrator). However it did not seem to do much as whatever ran -  or did not run - disappeared almost immediately and returned me to the command prompt.

Until this point I have not had any issues running Microsoft Update on the P1801.

Let me know how to proceed and I thank you for your time.

My issue is resolved and I thought it might help someone although most the following is more of background value for many of you.

First of all, the core problem that caused the problem in applying KB29919355 was that the Windows Component Core on my Asus AiO P1801 was corrupted - quite badly as a matter of fact. It took a repair re-install of Windows 8.1 to fix the corruption and finally allow the update to successfully conclude.

Second of all - thank you Susan for responding quickly to my request and assigning a cordial and thorough Microsoft tech who spent about two hours troubleshooting the various problems that the corruption of what is essentially the heart of Windows had caused. Creating a new user was necessary since my administrator-level login was also corrupted and would not complete tasks. After booting Windows 8.1 clean (especially disabling my third-party Emsisoft firewall and anti-Malware - more on them in a bit!), the tech was able to perform tasks that I had not been able to do in recent days (access the Store from the Metro tile, open other Metro tiles and run most administrator-level CLI commands successfully.)

Third, the question arises - what caused the corruption? Be advised that the following is speculation and only time will tell if it is indeed THE cause. The tech relied on his experiences with other similar corruption issues and speculated that it was the Emsisoft Anti-Malware/Anti-Virus program that may have caused the damage to the component core. Although he admitted to not being familiar with Emsisoft products he had seen another anti-virus vendor product cause corruption due to it lacking full compatibility with 8.1 - most of you may know that the 8.1 upgrade occasioned MAJOR changes in the OS core. In other words, compatibility with 8 did NOT mean compatibility with 8.1.

I am currently waiting to hear from Emsisoft whether their product is fully compatible with Windows 8.1 - they state on their site that it will work with Windows 8 but no specific mention (that I could find anyway) was made to it being compatible to 8.1.

Anyway, again my thanks to a stellar response from Microsoft on this - and I shall be much more vigilant about installation of intrusive products (like security programs, anti-virus, etc.,) without making absolutely CERTAIN that they are FULLY compatible.

And I am learning to re-appreciate the simple pleasure of the included Windows Firewall and Windows Defender while I research third-party compatibility with Windows 8.1!
