How to Fix Windows Update Error 0x80073701 Easily

If you’re encountering Windows Update error 0x80073701, it means some system files are corrupted or missing, preventing updates from installing properly. Fixing this error ensures your system stays secure, up-to-date, and running smoothly. Before starting, ensure you have administrator access on your PC and an active internet connection. It’s also recommended to create a system restore point as a backup in case something goes wrong during the repair process.

What You’ll Need

• Administrator access to your Windows PC
• Stable internet connection
• Some free time to perform troubleshooting steps
• Optional: Windows Media Creation Tool or installation media (if advanced repairs are needed)

Step-by-Step

1. Restart Your Computer: Begin with a simple restart. Sometimes, temporary glitches resolve after a reboot, which might fix the error without further action.
2. Run the Windows Update Troubleshooter:
   • Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters.
   • Select ‘Windows Update’ and click ‘Run the troubleshooter.’
   • Follow on-screen instructions and apply suggested fixes.
3. Use the System File Checker (SFC):
   • Press Windows key + X and select ‘Command Prompt (Admin)’ or ‘Windows PowerShell (Admin)’.
   • Type: sfc /scannow and press Enter.
   • Allow the scan to complete. If it finds corrupted files, it will attempt to repair them automatically.
4. Run the Deployment Image Servicing and Management (DISM) Tool:
   • Open Command Prompt or PowerShell as administrator.
   • Type: DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
   • This process may take some time; do not interrupt it.
5. Reset Windows Update Components:
   • In the admin Command Prompt, run the following commands one by one:
     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

6. Check for Windows Updates Again:
   • Go to Settings > Update & Security > Windows Update.
   • Click ‘Check for updates’ and see if the issue persists.
7. Update Drivers and Software:
   • Outdated drivers can interfere with updates. Use Device Manager to update drivers or visit manufacturer websites.
8. Perform a Clean Boot:
   • Type msconfig in the Run box (Windows key + R) and press Enter.
   • Under the Services tab, check ‘Hide all Microsoft services’ and click ‘Disable all.’
   • Go to the Startup tab and click ‘Open Task Manager.’
   • Disable all startup items, then restart your PC.
   • Try updating Windows again. If successful, re-enable services and startup items gradually.
9. Use Windows Media Creation Tool for a Repair Install:
   • If all else fails, download the Media Creation Tool from Microsoft’s website.
   • Create installation media on a USB drive or DVD.
   • Run setup.exe from the media and choose ‘Upgrade this PC now’ to repair Windows without data loss.

Common Mistakes

• Ensure your PC has enough free disk space—at least 20GB is recommended for updates.
