Status on September 2, 2026: this error has hit the headlines twice this year — a documented bug wave in April 2026 (fixed by Microsoft's emergency update KB5086672) and a stuck-package issue on upgraded 24H2/25H2 PCs in June 2026. If yours is one of those, the fix is short. If it is local corruption, this guide walks the full safe ladder — no reinstall, no "fixer" tools.

You click Check for updates, the download finishes, the install bar fills up… and then Windows gives up with error 0x80073712 — often with the message "Some update files are missing or have problems." You retry. Same failure. Sometimes it repeats every single month.

Here is the honest picture: 0x80073712 is not a virus and not a sign your PC is dying. It means Windows Update's internal storage of system files — the component store — is damaged, or a half-installed update package is stuck in the queue. Below you will find out which of the three situations you are in, and the exact safe fix for each.

Quick Answer

Error 0x80073712 means the Windows component store is corrupt or an update package is stuck. Fix order: (1) restart and check for updates again — documented bug waves were fixed automatically by KB5086672. (2) Run the Windows Update Troubleshooter. (3) Repair the store with sfc /scannow + DISM /Online /Cleanup-Image /RestoreHealth. (4) Reset Windows Update components. (5) Remove the stuck package with the deep DISM command. (6) In-place repair upgrade — keeps all your files and apps. None of these delete your data.

Key Takeaways

  • 0x80073712 stands for ERROR_SXS_COMPONENT_STORE_CORRUPT — damaged update storage, not malware.
  • Two documented Microsoft bug waves caused it in 2026: the KB5079391 optional update (April, fixed by KB5086672) and monthly-update failures on PCs upgraded to 24H2/25H2 (June).
  • Most one-off cases clear with the troubleshooter + SFC + DISM triple — about 20 minutes total.
  • If it comes back every month, a stuck cumulative package is the usual culprit — Fix 5 targets exactly that.
  • The ceiling is an in-place repair upgrade: refreshes Windows completely while keeping files, apps, and settings.
  • Never use registry cleaners or "0x80073712 fixer" EXEs from ads — that is how a 10-minute fix becomes a dead Windows.

What error 0x80073712 actually means

Windows keeps a protected warehouse of every system file version it may ever need, called the component store (the WinSxS folder). Before installing an update, Windows checks that warehouse's manifest — the inventory list. Error 0x80073712, ERROR_SXS_COMPONENT_STORE_CORRUPT, means that check failed: the inventory and the shelves no longer match. Something is damaged, missing, or a package is half-installed and blocking the queue.

Three different situations produce the same code — and the fastest fix depends on which one you are in:

Your situation Likely cause Fastest path
Started around March–April 2026 after an optional update Documented bug wave — KB5079391 broke updates on Windows 11 24H2/25H2 Fix 1 — Microsoft's emergency KB5086672 clears it
PC was upgraded to 24H2/25H2; monthly updates keep failing with the same code Documented stuck cumulative package Fix 5 — the deep DISM remove command
First time, random, or after a sudden power loss during an update Local component store corruption Fixes 2 → 3 → 4 in order

Not sure which version of Windows you are on? Press Windows + R, type winver, press Enter. If you were recently moved to 25H2, it also worth skimming Windows 11 25H2 problems: real issues and safe fixes — this error code is one of that update's documented leftovers.

The 6 fixes, in safe order

1. Restart, then check for updates again

It sounds too simple, but it is step one for a reason: after the April 2026 bug wave, Microsoft shipped KB5086672 as an emergency out-of-band update that resolves exactly this error — and it installs automatically through Windows Update. Restart, go to Settings > Windows Update, click Check for updates, and let everything install, restarting as many times as asked.

If Windows Update itself refuses to fetch it, download KB5086672 manually from the official Microsoft Update Catalog (catalog.update.microsoft.com) — never from a mirror site. And if your update gets stuck downloading instead, see Windows 11 update stuck at 0%, 99%, or 100%.

2. Run the Windows Update Troubleshooter

Go to Settings > System > Troubleshoot > Other troubleshooters, and next to Windows Update click Run. It takes a few minutes, resets the update service plumbing quietly, and applies any fix it finds. When it finishes, restart and check for updates again before moving on.

3. Repair the component store: SFC + DISM

This is the core repair for genuine corruption. Open Command Prompt as administrator (right-click Start > Terminal (Admin)) and run these one at a time, each taking several minutes:

DISM /Online /Cleanup-Image /RestoreHealth

sfc /scannow

The first command downloads clean copies of damaged store files from Microsoft; the second repairs system files using that now-healthy store. If DISM stalls around 62%, that is normal — let it sit. Two honest notes from documented cases: third-party antivirus can block DISM from touching WinSxS (add exclusions for C:\Windows\WinSxS and dism.exe, or temporarily disable it and re-enable after), and some stubborn stores need a second RestoreHealth pass after a restart.

4. Reset the Windows Update components

This clears the update cache and rebuilds the queue — it fixes cases where the download itself arrives damaged. In an admin Command Prompt, run one line at a time:

net stop bits
net stop wuauserv
net stop cryptsvc
ren %systemroot%\SoftwareDistribution SoftwareDistribution.bak
ren %systemroot%\system32\catroot2 catroot2.bak
net start cryptsvc
net start wuauserv
net start bits

Notice the commands rename the folders instead of deleting them — Windows rebuilds fresh copies, and the old ones remain as .bak until cleanup. Restart and check for updates.

5. The deep fix: remove the stuck package

If the error returns every month on a PC that was upgraded to 24H2 or 25H2, one cumulative update package is stuck half-installed, and every new update trips over it. Microsoft's documented mitigation is to remove that package. First find its exact name:

dism /online /get-packages | findstr /i "Package_for_RollupFix"

Then remove the newest one (yours will have a different build number):

dism /online /remove-package /packagename:Package_for_RollupFix~31bf3856ad364e35~amd64~~26100.1742.1.10

Restart, then immediately go to Windows Update > Check for updates so a fresh, healthy cumulative installs in its place. You are not left unprotected — you are swapping a broken package for the current one.

6. In-place repair upgrade — the ceiling, not a reinstall

If the store is too damaged for the commands above, the official fix is a repair install over the top: it lays down a fresh copy of Windows while keeping all your files, apps, and settings. You need at least 40 GB free on C:, and you must pick the same language as your current Windows. From Microsoft's official download page (microsoft.com/software-download/windows11), get the ISO, open it in File Explorer, run setup.exe, choose Keep personal files and apps, and let it work — expect 30–60 minutes and a few restarts. Disconnect from the internet and pause third-party antivirus during the run for the cleanest result.

Do this, never that

✅ Safe and effective ❌ Breaks things further
Run every command as administrator, one line at a time Pasting entire "fix-all" scripts from forums and YouTube descriptions
Rename SoftwareDistribution with services stopped Deleting it (or WinSxS — never touch that folder manually) while services run
Download KB files only from the Microsoft Update Catalog Downloading ".msu fixes" from mirror sites or file hosters
Temporarily pause antivirus during DISM, re-enable after Leaving antivirus off "until it works," or installing a second one
In-place upgrade that keeps files and apps Registry cleaners and "0x80073712 fixer" EXEs from search ads

One sitting, in order — stop as soon as updates install cleanly:

  1. Restart > Check for updates (Fix 1).
  2. Windows Update Troubleshooter (Fix 2).
  3. DISM RestoreHealth + SFC (Fix 3).
  4. Reset update components (Fix 4).
  5. Recurring monthly failure? Remove the stuck package (Fix 5).
  6. Still failing? Repair install over the top (Fix 6).

Frequently asked questions

Is error 0x80073712 a virus?

No. It is an internal Windows code meaning the update component store is damaged. The only virus risk here is the "fixer tool" ads that exploit error codes — close those and use the fixes above.

Does 0x80073712 delete my files?

No, and none of the six fixes delete them either — even the in-place repair upgrade explicitly keeps files and apps. Keeping regular backups is still good hygiene before any major repair.

Why does this error come back every month?

Almost always a stuck cumulative update package from an earlier upgrade. Each new monthly update trips over it. Fix 5 removes exactly that package so the queue can finally clear.

What is the difference between 0x80073712 and 0x800f0993?

They are siblings — both component-store/CBS failures documented together on PCs upgraded to 24H2/25H2, and both respond to the same ladder of fixes in this guide.

DISM stops at 62% or fails. What now?

Wait it out first — a long pause near 62% is normal. If it truly fails, check antivirus exclusions for WinSxS and dism.exe (a documented cause), restart, run RestoreHealth a second time, then continue with Fixes 4, 5, and 6 in order.

Can my antivirus cause this error?

Yes — there are documented cases of security software locking the component store so DISM cannot repair it. Adding exclusions (or temporarily disabling it during the repair, then re-enabling) resolves it. Your PC stays protected by Windows' built-in defenses in the meantime.

Do I have to reinstall Windows from scratch?

Almost never. The in-place repair upgrade (Fix 6) refreshes Windows completely while keeping your files, apps, and settings — a clean reinstall is the absolute last resort, not the next step.

The bottom line

Error 0x80073712 looks scary because it wears a hex code, but it is really a warehouse problem: damaged shelves or a stuck delivery. Most cases clear in twenty minutes with the troubleshooter and SFC/DISM; the documented 2026 bug waves were fixed by Microsoft itself; and the worst realistic case is a repair install that keeps everything. Work the ladder in order, stop the moment updates flow again, and treat any advertisement promising a one-click cure as the actual malware. For everything else Windows may throw at you, All Guides is kept up to date.
