Microsoft Issues Emergency Fix for Windows 11 Update Installation Errors

Late last week, Microsoft released its KB5079391 non-security feature update for Windows 11, which was officially pulled due to widespread installation errors. Today, the company is issuing the out-of-band KB5086672 update to address this problem, as Microsoft has identified the source of the issue and the update can now be safely applied. This latest out-of-band KB5086672 update includes the KB5079473 package released on March 10, KB5085516 released on March 21, and the previously pulled KB5079391 released on March 26. Microsoft has combined all of these into the new KB5086672 package, which addresses the issues that appeared and introduces a variety of new features. Finally, the old installation error message, “Some update files are missing or have problems. We’ll try to download the update again later. Error code: (0x80073712),” has been resolved for good.

Microsoft notes that this out-of-band update is available through Windows Update for devices running Windows 11 that have already installed KB5079473 or a later update. It is also available for manual download from the Microsoft Update Catalog. Currently, there are no known issues with this update, and if any arise, Microsoft will highlight them on their support documents website. Interestingly, KB5086672 is one of the first steps by Microsoft toward resolving the issues users have experienced with Windows 11 updates, and hopefully just the beginning of the overhaul that Microsoft has promised. Future non-security feature updates could also focus on other quality-of-life improvements, and installation errors should become less common.
