Windows 0x80073712 Component Store Corrupted
Component Store Corrupted — a required Windows Update component is damaged
What 0x80073712 Means
The 0x80073712 error on the Windows System Errors indicates component store corrupted — a required windows update component is damaged. This typically occurs due to corrupted files in the component store (winsxs folder).
Error 0x80073712 indicates that Windows Update cannot proceed because internal servicing files are inconsistent or missing. The component store maintains all update manifests and payloads, and any corruption blocks future installations.
Technical Background
The Windows Component Store (WinSxS) is a centralized repository of every component, manifest, and file version used by the operating system. When servicing operations detect a hash mismatch or a missing manifest entry, 0x80073712 is raised to prevent inconsistent state.
Unlike generic update failures, this error specifically points to the servicing stack infrastructure rather than a network, authentication, or policy problem. Recovery involves rebuilding or repairing the store's internal consistency.
Common Causes
- Corrupted files in the component store (WinSxS folder)
- An interrupted update left partial installation files behind
- Disk-level errors damaged system update manifests
Typical Scenarios
- A cumulative update fails repeatedly after a power loss during a previous update cycle
- The system reports pending updates that cannot be installed or rolled back
What to Know
Running the built-in system file verification utilities and the update troubleshooting tool are the standard diagnostic approaches. Persistent corruption may require an in-place repair of the component store from a known-good image.
