Error 0x80073712 usually means a file needed by Windows Update is damaged or missing.

For a Windows 11 Home device on 25H2, use this order:

1. Run the Windows Update troubleshooter
   • Open the Get Help app and run the Windows Update troubleshooter.
   • This can automatically diagnose and fix common update problems.
2. Repair the component store
   • Open Command Prompt as administrator.
   • Run:

          DISM.exe /Online /Cleanup-image /Restorehealth
     

   • This is the documented fix for 0x80073712.
3. If the failed update was installed from a shared folder or .msu file
   • There is a known issue in Windows 11 25H2 where WUSA or double-clicking a .msu from a network share containing multiple .msu files can fail.
   • Save the .msu file locally on the device and install it from there instead.
   • After restart, wait at least 15 minutes before checking Settings > Windows Update > Update history, because the restart-required message can be temporary.
4. Install the latest cumulative update
   • The WUSA shared-folder issue was resolved by updates released March 24, 2026 (KB5079391) and later.
   • Installing the latest security update includes that fix.
5. If the update still fails
   • A repair reinstall is the next supported path. In Microsoft Q&A examples for persistent 0x80073712 on Windows 11, the accepted resolution was:
     • Go to Settings > System > Recovery
     • Under Fix problems using Windows Update, select Reinstall now
   • This repairs Windows while keeping files, apps, and settings.

If the failure is specifically happening through normal Windows Update and not from a shared-folder .msu, steps 1, 2, and 5 are the relevant ones.
