Microsoft recently made available the Windows 8.1 Update for all Windows 8.1 users via the Windows Update service. However, many users are facing an issue that prevents the update from being installed. It fails with some error code, usually 0x800f081f or 0x80071a91. If you have a similar issue, then you need to do the following steps.
First, you need to clean up the component store of Windows 8.1 and remove the failed KB2919355 package.
- Open an elevated command prompt.
- Enter the following command:
dism /online /remove-package /packagename:Package_for_KB2919355~31bf3856ad364e35~amd64~~6.3.1.14
This will remove the KB2919355 package from the component store.
- Now run DISM with the following options:
dism /Online /Cleanup-Image /StartComponentCleanup
This command will clean up other components in the store which have issues.
Now, try to install the KB2919355 package again using Windows Update. Now it should be installed.
If it cannot be installed again, you should try to refer to KB2939087. Follow the instructions at the Microsoft Support web site to install it and reboot your PC.
If it is still failing to install then you can try repairing your corrupt component store using these instructions.
That's it. Feel free to tell us in the comments which solution exactly you used to fix the Windows 8.1 Update installation issue.

thanks! i will try on my friend’s laptop
fixed! thanks!
I’ve been having this problem (update won’t install) for a few days… I did step 1 (remove the package), then step 2 (image cleanup) which ran for a long time but was ultimately successful. I then tried Windows Update again but that failed.
Was a reboot required before trying Windows Update again? I ask as ultimately I restarted my machine and it took a long time to start up, with a message that said something like you see when you first install Windows 8 (“getting your machine ready”, or words to that effect).
This morning I logged on and Hurray – that stubborn update has installed(!) Thanks for posting this solution.
You are welcome.
I am happy that it was helpful for you.
Hi, I had a lot of trouble with this update.
What I had to do:
1 – Use elevated command prompt with the commands of this post
But when I tried to install the KB2919355 update it always failed.
What worked for me:
2 – Turn on automatic updates (I was using manual update checking and installing)
Then I rebooted and the updated installed automatically without failure.
So the key is that with automatic updates install feature disabled, this KB always failed in my desktop.
Thanks,
Ivan.
