Not an April Fool’s joke, Microsoft has issued another update aimed at fixing problems created by another recently launched one. Sadly, it would be a fun joke if Microsoft became capable of launching an update that didn’t need a fix, but as they say, it’s nice to dream. The good news this time around is that the previous KB5079391 non-security update didn’t manage to break anything major; it simply wouldn’t install for everyone. Thankfully, KB5086672 is on hand and ready to remedy that issue, and hopefully not introduce any new problems for Windows 11 users.
“This out-of-band update for Windows 11, version 25H2 and 24H2 (KB5086672) is cumulative and includes updates from previous security and non-security releases.
This update includes the improvements and features that were introduced in the March 26, 2026 non-security preview update (KB5079391), along with a fix for an installation issue that affected some devices attempting to install that update.”

Machines with “Get the latest updates as soon as they’re available”, a risky endeavor these days, will automatically download through Windows update. It also includes quality improvements from KB5079473 and KB5085516. This latest update is also available for download from the Microsoft catalog, as well as for those whose systems have not automatically downloaded it. As mentioned above, this is a fix for a non-security update and a preview version at that, so no real harm was done, but many users are likely to agree that it would be nice if Microsoft could roll out updates across a reasonable span of time, say, maybe a month, which didn’t require follow-up patches to fix. The number of reports from users since the deprecation of Windows 10 last fall is enough to make folks wonder if there’s any quality assurance to be had in the update department. Needless to say, confidence within the Windows community is not at an all-time high when it comes to updating their devices.
