Microsoft continues to navigate the complexities of Windows 11 updates, a journey marked by both innovation and occasional missteps. Recently, the tech giant faced backlash due to the March non-security preview update, which left many users grappling with installation errors. In response, Microsoft has rolled out an out-of-band update designed to rectify these issues.
Out-of-band update
On March 26, the problematic preview update, identified as KB5079391, was introduced, bringing with it a range of new features and fixes for Windows 11 versions 25H2 and 24H2. Typically, such updates are optional, aimed primarily at IT administrators and power users eager to test new functionalities. However, this particular update proved troublesome for a significant number of users, who encountered an error message stating, “Some update files are missing or have problems. We’ll try to download the update again later. Error code: (0x80073712).” While some users, including myself, managed to install it without issue, the extent of the problem prompted Microsoft to take decisive action.
In light of the installation difficulties, Microsoft paused and subsequently withdrew the initial update. On the following Tuesday, the company introduced a replacement update, KB5086672. This new release not only incorporates all the enhancements from the previous update but also addresses the installation problems that had plagued its predecessor.
Microsoft announced, “An out-of-band (OOB) update was released today, March 31, 2026, to address this installation issue. This cumulative OOB update for Windows 11, versions 25H2 and 24H2 (KB5086672) supersedes all previous updates and includes all protections and improvements from the March 2026 Windows security and non-security preview updates, as well as this installation fix.”
How to get it today
For those already set to receive preview updates, the KB5086672 update should automatically download and install on their Windows 11 PCs. Users who do not have this feature enabled can easily check for the latest update by navigating to Settings, selecting Windows Update, and initiating a manual check.
Additionally, users have the option to manage their preferences regarding these optional preview updates. By accessing the Windows Update screen, they can toggle the switch for “Get the latest updates as soon as they’re available.” For those who prefer to wait, simply turning off this switch will allow them to receive the updates during the next month’s official Patch Tuesday rollout, ensuring they don’t miss out on any important features or fixes.
