Windows 11 Update Glitch: Microsoft Issues Fix

Windows 11 users experienced significant installation problems with a non-security preview update released on March 26. The update, identified as KB5079391, was intended for Windows 11 versions 25H2 and 24H2, introducing new features and fixes. However, many users encountered an error code (0x80073712), preventing the update from installing.

Following these widespread reports, Microsoft has since paused and removed the problematic update. On March 31, 2026, the company issued a replacement out-of-band update, KB5086672. This new cumulative update supersedes all previous ones for these Windows 11 versions. It incorporates all the benefits and fixes from the earlier preview update while specifically addressing and resolving the installation errors.

Users who have opted in to receive optional preview updates should see KB5086672 download and install automatically. Others can manually check for updates via Windows Update settings. This process ensures that users receive the intended improvements without the previous installation obstacles.
