10 Tech How-To

Fix Windows Update Error 0x80070032

Guide 10-13347 · Updated · Step by step

This guide walks you through fixing Windows Update error 0x80070032, which typically appears when an update fails to install due to file permission issues, corrupted system files, or a conflict with third-party software. By following the steps below, you’ll clear the error and get Windows Update working again.

What You’ll Need

  • Administrator access to the PC (you’ll need to confirm UAC prompts)
  • A stable internet connection
  • About 15–30 minutes of time
  • Optional: a backup of important files (good practice before system changes)

Step-by-Step

  1. Restart your PC. A simple reboot clears temporary glitches that sometimes cause update errors. After restarting, try running Windows Update again to see if the error persists.
  2. Run the Windows Update Troubleshooter. Go to Settings > System > Troubleshoot > Other troubleshooters (or Settings > Update & Security > Troubleshoot on older builds). Select Windows Update and click Run. Follow the prompts and let it apply any fixes.
  3. Clear the SoftwareDistribution folder. This folder stores temporary update files. Corrupted files here often cause 0x80070032. To clear it:
    1. Press Win + R, type services.msc, and press Enter.
    2. Right-click Windows Update and select Stop.
    3. Open File Explorer and navigate to C:\Windows\SoftwareDistribution.
    4. Delete all files and folders inside (if some are in use, skip them and continue).
    5. Go back to Services, right-click Windows Update, and select Start.
    6. Try updating again.
  4. Run the System File Checker (SFC). Corrupted system files can block updates. Open Command Prompt as administrator (search for cmd, right-click, and choose Run as administrator). Type sfc /scannow and press Enter. Wait for the scan to complete (it may take 10–15 minutes). If it finds and repairs issues, restart and try updating.
  5. Run DISM (Deployment Imaging Service and Management Tool). If SFC doesn’t fix it, run DISM to repair the system image. In the same administrator Command Prompt, type:
    DISM /Online /Cleanup-Image /RestoreHealth

    Press Enter and wait for completion (may take 20 minutes). Restart and retry the update.

  6. Check for disk errors. Open an administrator Command Prompt and run chkdsk /f /r. You’ll be prompted to schedule it for the next restart; type Y and restart. Let the scan complete, then try updating.
  7. Disable third-party antivirus temporarily. Some security software interferes with update files. Right-click the antivirus icon in the system tray and look for a “disable� or “pause protection� option. After disabling, try the update. Re-enable it immediately afterward.
  8. Perform a clean boot. This starts Windows with minimal drivers and startup programs, eliminating software conflicts. Press Win + R, type msconfig, and press Enter. On the Services tab, check Hide all Microsoft services, then click Disable all. On the Startup tab, click Open Task Manager and disable all startup items. Restart and try updating. Afterward, revert the changes (re-enable services and startup items).
  9. Manually download the update. If Windows Update still fails, go to the Microsoft Update Catalog, search for the KB number of the failing update (you can find it in Windows Update history), and download the standalone installer for your system architecture (x64 or x86). Run the downloaded .msu file and follow the prompts.
  10. Reset Windows Update components. As a last resort, reset the update components manually. In an administrator Command Prompt, run the following commands one by one, pressing Enter after each:
    net stop wuauserv
    net stop cryptSvc
    net stop bits
    net stop msiserver
    ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
    ren C:\Windows\System32\catroot2 catroot2.old
    net start wuauserv
    net start cryptSvc
    net start bits
    net start msiserver

    Restart your PC and try updating again.

Common Mistakes

  • Skipping the restart after SFC or DISM. These tools often need a reboot to fully apply repairs; not restarting can leave the error unresolved.
  • Deleting the entire SoftwareDistribution folder without stopping the Windows Update service. This can cause access denied errors or leave the service in a bad state.
  • Forgetting to re-enable antivirus or clean boot settings. Leaving your system in a disabled state is a security risk and can cause other issues.
  • Running SFC without administrator privileges. It will fail with an error message; always right-click Command Prompt and choose “Run as administrator.�

Tips

  • Keep your system backed up. Before major repairs, create a restore point (search “Create a restore point� in the Start menu) so you can roll back if something goes wrong.
  • Check for pending reboots. Sometimes a pending restart from a previous install blocks new updates. Restart fully (not shut down) to clear it.
  • Use the Media Creation Tool as a last resort. If nothing works, you can use the Windows Media Creation Tool to perform an in-place upgrade, which reinstalls Windows while keeping your files and apps. This often fixes stubborn update errors.

Troubleshooting

If the error persists after all steps, try the following:

  • Check the Windows Update log. Open Event Viewer (eventvwr.msc) and look under Windows Logs > Setup for errors around the time of the failed update. The error details may point to a specific component.
  • Run the update in safe mode. Boot into Safe Mode with Networking (hold Shift while clicking Restart, then go to Troubleshoot > Advanced Options > Startup Settings > Restart > press 5). Try updating from there, as it loads minimal drivers and services.
  • Check disk space. Ensure you have at least 20 GB of free space on the system drive. Low disk space can cause update failures.
  • Look for third-party disk cleanup tools. Some tools that “clean� the WinSxS folder can break updates. If you’ve used such tools, consider running DISM with the /StartComponentCleanup option (as administrator) to repair the component store.
  • If all else fails, perform a repair install. Use the Media Creation Tool to download the latest Windows ISO and run setup.exe from within Windows. Choose “Keep personal files and apps� to reinstall Windows without losing data.

Frequently Asked Questions

What does error 0x80070032 mean?

It’s a Windows Update error that usually indicates a problem with file permissions or corrupted system files. It can also occur when an update tries to write to a location that’s blocked or missing.

Will I lose my files if I follow these steps?

No. The steps here only delete temporary update files (SoftwareDistribution) or repair system files. Your personal documents, photos, and applications remain untouched.

How long does the DISM command take?

DISM can take anywhere from 10 to 30 minutes, depending on your system speed and the extent of corruption. It may appear stuck at a certain percentage; that’s normal—let it finish.

Can I skip the clean boot step?

Yes, but if the error is caused by third-party software, clean boot is the most effective way to identify it. If you’re short on time, try the other steps first.

Why does the error appear on some updates but not others?

It often depends on which files the update needs to modify. If a specific file is corrupted or permission-locked, only updates touching that file will fail.

Is there a way to prevent this error in the future?

Keeping your system up to date, avoiding third-party “system cleaner� tools, and regularly running SFC (once a month) can reduce the risk. Also, ensure you have enough free disk space.
