KB5079391 is no longer available for download as Microsoft investigates error 0x80073712 during installation.
Earlier this week, Microsoft released KB5079391, this month's non-security update for Windows 11 version 24H2 and 25H2. As usual, the latest non-security update brought various feature updates and improvements. However, a few days later, Microsoft discovered a bug critical enough to halt the rollout.
Microsoft has updated the official support article for KB5079391 with a new entry in the changelog section. The company said that the rollout had been paused due to installation errors, particularly error 0x80073712. There is no information what systems are affected or what causes the error to happen, but it seems that the problem is widespread enough for Microsoft to recall the update for all users.
Now, if you go to Settings > Windows Update and check for available updates, Windows 11 will only show you KB5085516, which is the most recent out-of-band update released to address bugs with Microsoft Account in various Windows apps.
Microsoft does not say when KB5079391 will be available for download once again. Traditionally, changes in non-security updates arrive to all users in mandatory Patch Tuesday updates, so Microsoft has over two weeks to fix it ahead of the April 2026 Patch Tuesday release. In case you missed it. KB5079391 introduced Narrator improvements, changes to Smart App Control (it no longer requires reinstalling Windows to re-enable itself), multiple display improvements with 1000Hz+ refresh rate support, and more.
In other Windows Update news, Microsoft recently promised to fix Windows 11 and its pain points. As part of the plan, Microsoft wants to let users pause Windows Update indefinitely, improve update reliability, and more. You can read about the promised changes in our dedicated article here.
