Another effective method to fix Windows Update error code 0x80070003 is to reset the Windows Update components. Over time, update services and cache files can become corrupted, preventing Windows from downloading or installing updates properly.
Resetting these components helps clear damaged data and restore the default update configuration.
This process usually involves stopping Windows Update services, clearing the SoftwareDistribution and Catroot2 folders, and then restarting the services again. These folders store temporary update files, and if they are corrupted, they can directly trigger error code 0x80070003.
After resetting the components, restart your computer and try running Windows Update again to see if the issue is resolved.
3. Restart Windows Update Services
Restarting Windows Update-related services is another effective way to fix Windows Update error code 0x80070003, especially when the update process is stuck or not responding correctly.
Two key services play an important role in the update process:
- Windows Update Service
- BITS (Background Intelligent Transfer Service)
These services handle the downloading, processing, and installation of updates. If they stop running properly or become unstable, Windows may fail to locate or process update files, resulting in errors like 0x80070003.
To fix this, restart both services through the Services panel or Command Prompt. Once restarted, these services will refresh their processes and re-establish proper communication with Windows Update servers.
After restarting them, run Windows Update again to check if the issue has been resolved.
4. Run System File Checker (SFC)
Running the System File Checker (SFC) is an important step to fix Windows Update error code 0x80070003, especially when missing or corrupted system files are causing the issue.
To run the tool, open Command Prompt as Administrator and enter:
sfc /scannow
This command scans your entire system for corrupted or missing Windows files and automatically repairs them using cached system copies. If system file corruption is the reason behind the update failure, this step can often resolve it.
After the scan is complete, restart your PC and try Windows Update again.
5. Run DISM Tool
If the SFC tool does not fully fix Windows Update error code 0x80070003, the next step is to use the DISM (Deployment Image Servicing and Management) tool.
Open Command Prompt as Administrator and run:
DISM /Online /Cleanup-Image /RestoreHealth
This command repairs the Windows system image itself, fixing deeper corruption issues that SFC cannot handle. DISM restores the health of the Windows image by downloading replacement files from Microsoft servers.
Once the process is finished, restart your computer and run SFC again if needed, then check Windows Update to confirm whether error code 0x80070003 has been resolved.
6. Check Disk Errors (CHKDSK)
Running CHKDSK is an important step to fix Windows Update error code 0x80070003, especially if the issue is caused by storage or file system corruption.
Open Command Prompt as Administrator and run:
chkdsk /f /r
