After installation of KB4056892 boot failure, after roll-back error 0x800f0845

I'm pleased to say, I've now got my system working again (HP Pavilion dv7-2110sa with AMD Turion X2 CPU...

After the initial lockup problem following Windows automatic installation of the dodgy KB4056892 (OS Build 16299.192), I installed the  "Show or hide updates" troubleshooter package and used this to prevent the KB4056892 patch until Microsoft fixed the issue.

The latest patch KB4058258 is supposed to resolve the problem so tonight I ran the "Show or Hide Updates" troubleshooter again and disabled the block on KB4056892. Windows immediately started to download the troublesome update again! However, BEFORE it rebooted the machine again, I manually downloaded the latest update KB4058258 (OS Build 16299.214) from the Microsoft Update Catalogue Website from here: http://www.catalog.update.microsoft.com/Search.aspx?q=KB4058258

I manually ran this update. And thankfully after the PC has been rebooted twice, all is now well.

It's good Microsoft eventually got round to fixing this. But we should never have got into this situation in the first place. Before releasing the original patch it should have been thoroughly tested on a wide variety of hardware and processor platforms!

Good to hear you have resolved the boot issue with your machine. But I'm curious, if you had booting troubles, how were you able to install and run the "Show/Hide Updates" utility? I can run this while on build 1607 because the system boots fine. That wouldn't have worked though using build 1709 (non-bootable). But based on earlier discussions above, perhaps I need to find and uninstall KB4056892 since it is not part of build 1709. Then, install patch KB4057142. THEN, attempt to re-install 1709 and hope for the best.

After the system initially installed the dodgy update (KB4056892) it locked up at the Windows Logo like everyone else's machine has. I did a forced shutdown (press and hold power button for 4 seconds), restart. Did the forced shutdown 3 times in total and eventually Windows will roll back the update. However as soon as it boots it will try to download and install the KB4056892 update again. At this point I ran the "Show or hide updates" troubleshooter package to stop it trying to install again until Microsoft issued the bug fix on 31 Jan. You should not need the "Show or hide updates" troubleshooter package anymore as long as you manually install the latest update like I did. Good luck.

I am happy for anyone who had this lock up issue and managed to get the KB to work. If not, rather than throw out the older machine, try Linux Mint. Easy and free, looks and acts much like Windows. And you will be stunned by how much more responsive the machine will be (so much so I also put it on another older laptop which was not locking up). And you can install it side by side and access your old files or go back to Windows if you want.

you have Win10-1607 and need very different patch:

Did this solve your problem?

#metoo :)

I had paused updates and the system remained stable with no reboot but the bad update pending. I downloaded and manually installed the aforementioned fix, rebooted and all was fine. Un-paused updates, searched/applied many and rebooted many times without problems. Thanks to EVERYONE for the attention and help.
