Windows 11 KB5079391 Pulled After 0x80073712 Installation Error Disrupts Rollout

Microsoft has paused the rollout of the Windows 11 update KB5079391 for versions 24H2 and 25H2 after users began encountering installation issues. The update, which introduced several improvements and fixes, is no longer being distributed through Windows Update.

KB5079391 originally aimed to deliver new features alongside fixes for known issues, including problems affecting WUSA network installations. However, the rollout did not go as planned, forcing Microsoft to take action shortly after release.

Installation Error 0x80073712 Forces Microsoft to Halt Update

The company halted the rollout due to widespread reports of installation error 0x80073712. This error typically points to missing or corrupted system files, which can prevent updates from completing successfully.

Microsoft has not confirmed the exact root cause of the issue or specified which devices are affected. Still, the scale of the problem appears significant enough to justify pulling the update entirely from distribution channels.

KB5079391 Replaced by Out-of-Band Update KB5085516

Users checking for updates will no longer see KB5079391 listed. Instead, Microsoft is now offering KB5085516, an out-of-band update designed to address Microsoft account-related issues.

This replacement suggests that Microsoft is prioritizing stability fixes while it works on resolving the installation problems tied to KB5079391.

No Timeline Yet, But Fix Expected Soon

Microsoft has not shared a timeline for when KB5079391 will return. However, the update is expected to be re-released before the April 2026 Patch Tuesday cycle, likely with fixes that address the installation failures.

Given that this update is intended for broader rollout, the company will need to ensure stability before pushing it again to all eligible devices.

In other news, Microsoft has also warned users about upcoming Kerberos authentication changes that could impact enterprise environments and login workflows.
