Microsoft Releases Out‑of‑Band Patch to Fix Windows 11 Preview Update Installation Failures

Microsoft has issued a new out-of-band update to address issues caused by a recent Windows 11 preview release, following widespread reports of installation failures. The problematic update (KB5079391) could not be installed on some devices.

Last week, Microsoft released the non-security preview update (KB5079391) for Windows 11 versions 25H2 and 24H2. It brings various improvements, including the ability to enable or disable Smart App Control without a clean install. This update also improves Windows Hello Fingerprint reliability for certain devices.

However, some users reported receiving error message 0x80073712 with the following error message when installing the update: “Some update files are missing or have problems. We’ll try to download the update again later.” Microsoft temporarily paused the rollout of this update to investigate the cause of failed installations.

“To prevent additional impact while the issue is investigated, Microsoft has temporarily limited the availability of this update,” Microsoft explained. “As a result, the update temporarily might not be offered through Windows Update.”

Microsoft’s push for more flexible Windows updates

Microsoft is improving how Windows 11 handles updates in response to long‑standing user frustration, with a stronger focus on flexibility and control. As part of these changes, the company plans to give users the option to delay or pause updates for extended periods. It will allow them to avoid disruptions and apply new versions on their own schedule rather than being pushed into frequent or unexpected installs.

Windows updates have a long history of running into trouble, with several past releases needing to be delayed, withdrawn, or urgently repaired after causing unexpected problems. Microsoft acknowledges these recurring issues and says it aims to reduce disruptions for customers.
