Error 0x80073712 points at the foundation: the component store that tracks every Windows system file is damaged, and the update engine will not build on a broken foundation. This error often arrives after months of minor servicing glitches that were ignored — failed updates, SFC finding corruption it could not fix, DISM errors — until the damage crosses the threshold where updates stop entirely.

The good news is that Microsoft built exactly the right tool for this: DISM’s RestoreHealth exists to repair the component store. The steps below start there and escalate through the deeper repairs for the cases where the standard fix is not enough.

Beneath every Windows update lies the component store — the WinSxS database that records every system file, package, and manifest on the machine. Error 0x80073712 means that database is damaged: the servicing engine consults its records, finds inconsistencies, and refuses to build on a broken foundation. This error rarely appears out of nowhere; it is usually the culmination of months of minor servicing neglect — failed updates dismissed, SFC warnings ignored, forced shutdowns during installs. The encouraging news is that Microsoft built precisely the right repair tool for this, and it works from the command line in most cases.

Why this happens

  • Corrupt WinSxS database: Damage to the component store’s records breaks servicing lookups.
  • Interrupted updates: Power loss or forced shutdowns during servicing leave half-written store entries.
  • Manual WinSxS tampering: Deleting “unneeded” files from the component folder destroys referenced components.
  • Aggressive cleaner tools: Cleaners that touch the component store cause reference breakage.
  • Disk errors: Bad sectors in the WinSxS area corrupt store files.
  • Failed driver installations: Crashed installs leave orphaned component references.
  • Manifest mismatches: Component manifests disagreeing with actual files confuse the engine.
  • Long-neglected servicing issues: Months of ignored minor corruption compounding into store failure.

How to fix it

Work through these in order — diagnose first, then act.

Hands off the WinSxS folder itself. It looks like wasted disk space, and every few years someone writes a guide suggesting manual deletion — that guide is how component stores get destroyed. The only safe way to trim the store is DISM’s StartComponentCleanup in Fix 5. Everything else in that folder is load-bearing.

Fix 1: Run DISM RestoreHealth

The primary repair for component store damage — start here.

  1. Open Command Prompt as administrator.
  2. Run DISM /Online /Cleanup-Image /RestoreHealth.
  3. Wait for full completion; do not interrupt it even if it seems slow.
  4. Restart the laptop and retry Windows Update.

The Windows 11 variant of this same error has a few OS-specific wrinkles — our 0x80073712 guide for Windows 11 covers them.

Fix 2: Run DISM with an explicit source if needed

When the online repair cannot fetch clean files, point it at a known-good source.

  1. Download the Windows 11 ISO matching your installed version.
  2. Mount the ISO and note its drive letter, for example E:.
  3. Run DISM /Online /Cleanup-Image /RestoreHealth /Source:E:\Sources\install.wim with the correct letter.
  4. If the ISO uses install.esd instead, adjust the path accordingly.
  5. Restart and retry the update.

Fix 3: Follow with System File Checker

Repair the protected files that depend on the restored store.

  1. In an admin Command Prompt, run sfc /scannow.
  2. Let it reach 100 percent and read the summary.
  3. Restart if it repaired anything, then test Windows Update.
  4. If SFC still reports unfixable corruption, continue below.

Fix 4: Check the CBS log for specifics

Identify exactly which components are damaged.

  1. Open C:\Windows\Logs\CBS\CBS.log after a failed repair attempt.
  2. Search for error entries near the end of the log.
  3. Note specific package, manifest, or file names mentioned.
  4. This detail guides the deeper repairs — or documents the case if you need further help.

Fix 5: Run a component cleanup

Clear superseded components that may be contributing to the inconsistency.

  1. In an admin Command Prompt, run DISM /Online /Cleanup-Image /StartComponentCleanup.
  2. For a deeper pass, add /ResetBase, understanding it removes the ability to uninstall updates.
  3. Restart afterward and retry Windows Update.
  4. Never clean WinSxS manually — only through DISM.
  5. For related store-corruption symptoms, see our 0x80070490 repair guide .

Fix 6: Check the disk thoroughly

Rule out storage damage that keeps recorrupting the store.

  1. Run chkdsk C: /f /r in an admin Command Prompt and restart to run it.
  2. Check SSD health with the manufacturer’s toolbox.
  3. If the disk shows bad sectors or health warnings, replace it — no software repair survives failing storage.
  4. After a clean disk check, rerun DISM RestoreHealth.

Fix 7: Reset the Windows Update components

Rebuild the update-side data stores alongside the repaired component store.

  1. Stop the services: net stop wuauserv, net stop cryptSvc, net stop bits, net stop msiserver.
  2. Rename: ren C:\Windows\SoftwareDistribution SoftwareDistribution.old and ren C:\Windows\System32\catroot2 catroot2.old.
  3. Restart the services and reboot.
  4. Retry Windows Update.

Fix 8: Perform an in-place upgrade repair

Rebuild the entire servicing stack while keeping files and apps.

  1. Download the Windows 11 ISO from Microsoft’s software download page.
  2. Mount the ISO and run setup.exe, choosing to keep personal files and apps.
  3. The upgrade reinstalls Windows over itself with a pristine component store.
  4. After completion, verify with DISM /Online /Cleanup-Image /CheckHealth and run Windows Update.

When DISM cannot repair the store even with an explicit source image, the damage has usually spread to the servicing stack itself — the very machinery DISM relies on. That is the point where the in-place upgrade in Fix 8 stops being optional: reinstalling Windows over itself replaces the servicing stack wholesale while keeping your files and applications. It sounds drastic, but it is a routine, well-supported procedure that takes under an hour and resolves essentially every component-store failure. Afterward, treat the experience as a lesson in update hygiene: let updates finish, keep cleaners away from system folders, and run a disk check at the first sign of trouble. For the related element-not-found error, our 0x80070490 guide covers the adjacent repairs.

Closing

A damaged component store sounds catastrophic, but it is one of the best-supported repair scenarios in Windows — DISM was built for exactly this. Work from RestoreHealth outward through the deeper repairs, respect the WinSxS folder by never touching it manually, and the servicing foundation comes back solid.

Frequently asked questions

What is the component store, and why does its damage break updates?
The component store, located in C:\Windows\WinSxS, is the master database of every Windows system file, package, and manifest. Every update consults it to determine what is installed and what needs changing. When the store is corrupted, the servicing engine cannot verify the system’s state and refuses to proceed — producing errors like 0x80073712. Repairing the store restores the engine’s source of truth.
Will DISM always fix 0x80073712?
DISM’s RestoreHealth is the primary and most successful repair for this error, resolving the majority of cases by replacing damaged store files with clean copies from Windows Update. It fails mainly when the damage is too extensive, when Windows Update itself cannot supply clean files, or when disk errors keep recorrupting the store. The deeper fixes in this guide cover those situations.
How long does DISM RestoreHealth take?
Typically 10 to 30 minutes depending on the extent of corruption and your internet speed, since it downloads clean replacement files. Let it run to completion without interrupting it — stopping DISM mid-repair can leave the store in a worse state. If it appears stuck, check Task Manager for disk and network activity before concluding anything.
Is it safe to touch the WinSxS folder directly?
No. Never manually delete or modify files inside WinSxS — it looks like wasted space, but every file there is referenced by the servicing database. Manual tampering is a fast track to exactly the corruption this guide repairs. Use DISM’s StartComponentCleanup for safe cleanup, and let the supported tools manage the store.
