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

Hi All,

After trying all the possible solutions you kindly shared on this thread, unfortunately none of them worked for me.

So I am sharing the solution I found, which worked fine for me on two different ASUS systems (one ROG notebook and one Ultrabook).

I made a system restore to a point pre-Windows 8.1 Update failure (in my case it was dates April 8th).

At this point I installed manually and one by one (NOT via Windows Update) each of the .msu files which are part of Windows 8.1 Update, and which you can download from the Microsoft web site from here:

http://www.microsoft.com/en-US/download/details.aspx?id=42335

IMPORTANT: Before doing that you must ensure that KB2919442 is installed on your system, since this is a pre-requisite to install Windows 8.1 Update.

If it is not installed, first of all install that update from here: http://www.microsoft.com/en-US/download/details.aspx?id=42162

IMPORTANT # 2: You must ensure to follow EXACTLY this installation order:

KB2919355, KB2932046, KB2937592, KB2938439 and finally KB2934018.

IMPORTANT # 3: After installing each one of those, you need to restart your PC. Please note that the biggest one - KB2919355 - can take a lot of time for full system restart, just allow Windows to complete all necessary post-installation operations.

As a final consideration, due to my personal experience with unsuccessful attempts to install Windows 8.1 Update on two different systems, I came to this conclusions: The reason of all the time-consuming issues we are all experiencing or have experienced since April 8th is Microsoft's fault. There was nothing wrong or damaged on our systems (in general, of course some systems might have already been corrupted before installing the update). It was the failed attempts to install Windows 8.1 Update via Windows Update which somehow damaged our systems, and in most cases none of the clever workarounds/solutions I've seen here worked.

Magically after restoring system to a pre-Windows 8.1 Update state, and by installing that update via the .msu install packages downloaded from the Microsof site and NOT via Windows Update, everything worked perfectly and our systems are no longer damaged or corrupted, and both shine with a brand new Windows 8.1 Update (which is a nice update, by the way for those who never liked the Metro/Modern UI).

And, especially, there's no need to reinstall the whole Win 8 or Win 8.1 from scratch, loosing all our programs, apps and personalization and therefore needing full working days to bring back machine configuration to actual status.

I can tell you for sure that my solution has already worked fine for few friends/colleagues of mine here in Italy.

I do hope it can help at least some of you to solve this extremely annoying and time-consuming issue.

I've been struggling with it since April 8th and I've wasted all my Saturday on that, but thank goodness I succeeded.

Please let me know if the above is working for you, too, I'd be curious to know.

Good luck!

C:\Windows\System32\DriverStore (must be an intel machine if intel, or amd machine if amd, x32 and x64 must match too)

C:\ProgramData\

C:\Users*username*\*

C:\Users\Public***

C:\Users\Default***

C:\User\DefaultAppPool***

Take these directories from a working install of windows 8.1.u1 (or any w8 that would succeed/has succeeded in updating), make sure ownership\permissions are set, and copy them back to your machine, but do not overwrite anything (extremely important). This will retain everything on your computer, but by not overwriting you are not "changing" anything your system depends on to operate. It places files that windows is searching for upon installing this kb that were missing, back. This allows the update to install, or it has in my case. Twice.

Image backup first.

I have fixed this problem on 2 machines now by doing this.

*** might not be necessary, but recommend doing so anyways (again you are copying, without overwriting, you are only adding files that the installer is looking for)

I have given up trying to upgrade to Windows 8.1 Update. Wasted a few days on this already. I tried everything including DISM RestoreHealth etc but that too fails.

Luckily the installation does not do any harm, my table still working, so I can still use it.

I have disabled the auto update in my Windows 8.1 tablet to prevent it from retrying to update again.

I will wait for another 1 or 2 months until this is (hopefully) resolved by Microsoft before retrying again.

Regards.
