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~~126.96.36.199
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.
