Microsoft released Windows 8.1 Update earlier this week and, as expected, not everyone was able to install the software on their Windows 8.1 PCs. This has caused the company to release at least two patches since Tuesday to fix installation problems.
Many people on the Microsoft Answers forum have reported getting the error code "0x800f081f" when trying to install the update. Microsoft has since released a patch for this specific problem. Others have reported that they are unable to uninstall IIS after you install the update in Windows 8.1 or Windows Server 2012 R2. Again, Microsoft has released a patch for that issue.
However, many of the people who have written in the Microsoft Answers forum claim that their install problems remain. Some have found that this workaround solves their issues:
Run CMD as administrator (Go to start screen, all apps, search CMD, right-click and select run as administrator)
Enter: dism /online /remove-package /packagename😛ackage_for_KB2919355~31bf3856ad364e35~amd64~~6.3.1.14
When step 2 has completed, enter: dism /online /cleanup-image /startcomponentcleanup
Retry the update!
