How To Clear Windows Update Cache in Windows 10 Easily

Over time, Windows Update cache can become cluttered or corrupted, leading to update errors, slow downloads, or failed installations. Clearing this cache can resolve common update issues, improve system performance, and ensure your Windows 10 stays up to date smoothly. Before starting, ensure you have administrator privileges on your computer, as these are required to stop services and delete cache files. This guide provides a straightforward, step-by-step process to clear the Windows Update cache safely and effectively.

What You’ll Need

• Administrator access to your Windows 10 PC
• Basic understanding of using Command Prompt or PowerShell
• Optional: a backup point or system restore point, in case you want to revert changes

Step-by-Step

1. Close all running Windows Update processes: Press Ctrl + Shift + Esc to open Task Manager. Look for any processes named Windows Update or wuauclt.exe. If found, right-click and select End Task.
2. Stop the Windows Update service: Click the Start menu, type cmd, right-click on Command Prompt, and select Run as administrator. In the Command Prompt window, type:

   net stop wuauserv

   and press Enter. Then type:

   net stop bits

   and press Enter. These commands stop the Windows Update service and Background Intelligent Transfer Service, which manage update downloads.

3. Delete the update cache files: Still in the Command Prompt window, navigate to the Windows Update cache folder by typing:

   del /s /q C:\Windows\SoftwareDistribution\Download\*

   and press Enter. This command deletes all files in the Download folder where update files are stored. If you want to be thorough, you can also delete the contents of:

   C:\Windows\SoftwareDistribution\DataStore\*

4. Restart the Windows Update service: In the same Command Prompt window, type:

   net start wuauserv

   and press Enter. Then type:

   net start bits

   and press Enter. This restarts the services necessary for Windows Update to function.

5. Check for updates: Open Settings by pressing Windows + I, navigate to Update & Security, then click Check for updates. Your system will now reinitialize the update cache and attempt to download updates afresh.

Common Mistakes

• Not running Command Prompt as Administrator — this prevents you from stopping services or deleting files.
• Deleting files from the wrong folders — ensure you only delete files within SoftwareDistribution and related directories.
• Forgetting to restart services after deletion — services must be restarted to re-enable Windows Update.
• Interrupting the process — do not close Command Prompt or Task Manager while commands are executing.

Tips

• Perform a system backup or create a restore point before deleting system files, to revert if needed.
• If issues persist, consider running the Windows Update Troubleshooter from Settings > Update & Security > Troubleshoot.
• Regularly clearing the update cache can prevent buildup and related errors over time.
• Ensure your Windows 10 is up to date after clearing cache to avoid security vulnerabilities and bugs.

Troubleshooting

If clearing the cache doesn’t resolve your Windows Update issues, try these additional steps:

• Run the Windows Update Troubleshooter: Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters > Windows Update.
• Reset Windows Update components manually by running a batch script designed for this purpose, which automates stopping services, deleting cache, and restarting services.
• Check your system clock and date — incorrect settings can interfere with update processes.
• Ensure your system has sufficient disk space for updates, typically at least 20 GB free.
• If problems persist, consider repairing system files using the System File Checker tool: open Command Prompt as admin and run

  sfc /scannow
