Error: 0x800F0922 when installing KB 2919355

To be clear, you aren't unpatched at this time.  All security updates through June are being released both with and without versions for KB2919355.

The only patches you are missing are ones that specifically post KB2919355 (one is fixing a hibernation issue introduced by KB2919355).

I can't say they aren't taking this seriously.  The revised KB2919355 shows they are.  I can say they aren't taking this as seriously as everyone in this thread would like (nor I).  I can only say that I'm sorry and understand your frustration.

Hi guys,

I was also struggling with these issues for many weeks now, and finally got it working today:

I just cleaned up my machine a little bit by removing SonicWALL VPN Client, OpenVPN, another VPN manager and a partitioning tool. I guess it had something to do with VPN indeed.

I made sure that no VPN adapters/connections remain (only standad ethernet adapter).

After that, I normally installed update 2919355 using Windows Update. During downloading I additionally disabled Windows Defender, since it seemed to be quite active by checking the update (according to Task manager) - I just wanted to go sure that it doesnt affect the installation process.

Thats all - really helped me out.

Best Regards and good luck,

Andreas

PS: It's still a shame that such things can break a system update installation.

I know the following to solve all KB2919355 issues, and pasted below are the two tutorials.  The first is one that was written to get rid of the component store corruption that 2919355 causes, of which the computer you're working on has.  You will need to do a repair install (tutorial at the bottom of Tutorial 1).  The second tutorial is how to get 2919355 installed after the repair install, however, you should be able to install 2919355 fine after the repair install.  If it still fails, then follow the second tutorial.

Hi. I have a question about this (and the other) proposed solutions -- how does KB2961908 ("security update for x64-based systems without KB2919355 installed") tie into these solutions? I'm getting error 800F0922 when trying to install KB2961908 -- my impression was that it is best to get this one installed first before trying to get KB2919355 working.. not sure if that is actually the case?

I can't recall at this point if I've already tried (and failed) to get KB2919355 itself installed after the former failed, and I'm bit reluctant to try to do so until figuring out what is the expected order.

Oops, looks like I've finally found a resolution for the KB2961908 installation issue independently of the above (for other folks faced with both, it was to first disable Secure Boot in the UEFI firmware).  Please disregard the question.

So now I'm left with KB2919355.. and after reading some of the above, I'm nervous about trying to install it via Windows Update vs downloading and installing standalone. I gather the latter might be safer.

Actually, I just checked my update history and confirmed that indeed, I'd been disciplined and hadn't yet tried to install KB2919355 at all before sorting out the KB2961908 issue.  Given all of the discussion above, how serious is the likelihood of attempting KB2919355 from Windows Update causing some form of filestore corruption? Is it indeed the general recommendation at this point for folks who haven't attempted it yet to prefer a standalone installation to Windows Update?

Hi,

I had exactly the same problem here with error code 800F0922. This was on a Dell XPS 12 running Windows 8.1 Pro x64.

I tried many of the suggestions listed here and elsewhere, including using the SFC and DISM tools but nothing worked.

However, once article I read mentioned the possibility of VPN software stopping it from installing. We use the Check Point Endpoint Security suite and a component of this is a VPN solution. I removed this but it made no difference. Then I decided to remove the entire suite, which also includes Full Disk Encryption, a Firewall and Media Encryption, for USB devices.

After this was removed and the disk was completely decrypted I attempted the install again, using the downloaded MSU file, file size 724,339,463 bytes.

This time it worked! I don't know what was stopping it but my guess would be something to do with the FDE component, as it does encrypt all partitions. Maybe there is some truth behind the idea that it could be free space on the System Reserved partition but I don't know for sure.

Anyway, hope this helps someone out there!
