Error: 0x80073712 when installing KB 2919355

I'm hoping for more people to respond as to whether the strange technique you discovered to get it installed works for them.

Many people won't be able to try it right away since computer makers decided to do away with proper install media sadly.

And I agree with you: refresh/reset is NOT AN ACCEPTABLE SOLUTION.

At least MS is not charging people for support cases... And in my case my payoff for ten hours of work was an actual install disk. My hourly rate is usually multiples higher than that though....

Your Win 8.1 install disk is gold. I was finally able to install the update after numerous failures but the update removed my restore points and corrupted my component store which left DISM /Restorehealth unable to repair the store. My computer came with an OEM version of Win 8. Without a 8.1 install disk I cannot repair the store without nuking everything and starting over with Win 8.0. Of course the OEM won't supply an 8.1 disk nor will Microsoft. Count your blessings for obtaining the repair media.

My computer also came with OEM Windows 8. I am VERY glad to have actual media now, and have made both a bootable USB drive of it as well as made a system image. (I *should* update my refresh wim at this point, but I don't know how and it looks fairly time consuming - I've put enough time into this already).

Have you opened a support case with MS? They are not charging for this issue (and rightly so!!!!), and they will log in to your computer and try to fix it remotely. They won't be able to and will tell you to refresh/reset -- tell them that's unacceptable, that you want to do a repair install and want them to send you a disc.

Anyone without an 8.1 ISO can make one... it's just a bit time consuming and is around 2 hours or so from start to completion.

EDIT:

The microsoft download tool spoken about in both of the forums at the bottom of this post is no longer accepting product keys, valid or generic, and thus will not work.

I do know there is a way to grab the same 8.1 installation files when a user updates to 8.1 via the windows store.  I can't recall which folder they're downloaded into, but if memory serves it's within the user's temp folder under app data - local.  A bit of research on google would provide the answer, however, nothing popped out right away when I just skimmed the search.  I do know the key to those temp 8.1 installation files is to copy all of them (as you can't cut and paste due to them being in use and once you exit the installer, they auto delete) before actually installing windows 8.1.  I hope this at least helps those who have a bit of time to research

For Pro users, it's going to be more simplistic than it will for non-Pro users... architecture doesn't matter.

For PRO users:

(tutorial will be in a link at the bottom which is worth a read as well)

1. If you haven't already done so, install Hyper-V by going to add/remove windows components.
2. Create a Virtual Machine and install Windows 8 onto it.
3. Download the Windows 8.1 installer from your Virtual Machine, run it, select "Install by Creating Media, then choose SAVE to USB*(This step is absolutely crucial and is what is used for the Win 8.1 ISO. I am unsure if non-Pro users have Hyper-V, but I think I read somewhere they don't)*
4. Once the files are downloaded, create an ISO from the files and make at leasttwo backups of the ISO (for example, I burned it to a DVD, saved it to my Media HDD within My Documents., and saved it to one of my NAS servers.

For Non-Pro users w/o access to Hyper-V:

1. You will have to do a bit of research on Google to find Virtual Management software that is free or offers a trial.  You only need to be able to use it for an hour, so the time frame of the trial doesn't matter.  You could also ask a family or friend with Pro if you can borrow their laptop for about an hour or ask if they could go through the steps above for you.
2. Follow steps 1 - 4 above.

EDIT: VMWare Workstation and VirtualBox are two free Virtual Management software applications.

You'll need generic Product Keys to access the installer, and these are as follows:

• Windows 8.1 Core/Home 334NH-RXG76-64THK-C7CKG-D3VPT
• Windows 8.1 Professional XHQ8N-C3MCJ-RQXB6-WCHYG-C9WKB
• Windows 8 Core/Home FB4WR-32NVD-4RW79-XQFWH-CYQG3
• Windows 8 Professional XKY4K-2NRWR-8F6P2-448RF-CRYQH
