KB5079473 Update Not Installing Error Code 0x800f0831/0x80073712 Windows 11 FIX

Error 0x80073712 generally means:

A file needed by Windows Update is missing or corrupted.

During installation, Windows tries to read required update components from the component store (WinSxS). If these files are missing or damaged, the update fails.

Common Causes of KB5079473 Error 0x80073712
1. Corrupted WinSxS Component Store (Most Common Cause)

The WinSxS folder stores system components and update manifests required for installing updates.

If it contains:

Missing .mum or .cat files

Corrupted package metadata

Inconsistent component references

Windows cannot assemble KB5079473.

2. Failed or Interrupted Previous Updates

If earlier updates:

Failed to install

Were rolled back

Were interrupted by restart or shutdown

they may leave the servicing system in an inconsistent state.

3. Corrupted Windows Update Cache

Damage in update cache folders such as:

SoftwareDistribution

Catroot2

can cause Windows to stage incomplete or corrupted update files.

4. Missing or Damaged Servicing Stack Update (SSU)

Cumulative updates depend on a working Servicing Stack Update.

If the SSU is missing, outdated, or corrupted, Windows may fail while processing update packages.

5. System File Corruption

Copy and paste this:
net stop bits
net stop wuauserv
net stop appidsvc
net stop cryptsvc
Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\*.*"
rmdir %systemroot%\SoftwareDistribution /S /Q
