Breaking Update: Here’s a clear explanation of the latest developments related to Breaking News:Microsoft Pauses Windows 11 KB5079391 Preview Update Following Install Failures– What Just Happened and why it matters right now.
Microsoft has paused the Windows 11 KB5079391 preview update after several systems reported installation issues with error 0x80073712. The update was for Windows 11 24H2 and 25H2 and first appeared as a non‑security “C‑week” cumulative release, as reported by Bleeping Computer.
Affected PCs reportedly displayed messages indicating that some update files were missing or encountered problems, prompting Windows to halt installation. Systems continued to run normally after the failure, and there is no current evidence of any data loss or boot issues directly tied to this update.
Microsoft has updated its release notes to say it has temporarily limited the availability of the update as it investigates the error.
KB5079391 was set to include quite a few changes, such as a new Smart App Control toggle that lets users switch the protection setting on or off without a clean install. It also promised better support for displays with refresh rates above 1000Hz, reliability improvements for HDR and USB4‑connected screens, and fixes for Windows Hello Fingerprint and Windows Recovery on ARM64 devices.
Microsoft expects to make these changes in a future cumulative update—likely the April Patch Tuesday release—once it fixes the installation problem.
