How to Clear Cache on Windows 10 for Better Performance

Over time, your Windows 10 system accumulates cached data from various applications, browsers, and system processes. Clearing this cache can help improve your computer’s speed, resolve loading issues, free up storage space, and enhance overall performance. Before starting, ensure you have administrator access to your Windows account, as some steps may require elevated permissions. Additionally, back up important data if necessary, though clearing cache is generally safe and non-destructive.

What You’ll Need

• A Windows 10 PC with administrator rights
• An internet connection (for browser cache clearing)
• Optional: A system cleanup tool (like Disk Cleanup, but Windows built-in tools are sufficient)

Step-by-Step

1. Close all open applications and browsers. Before clearing caches, close any programs and browser windows to prevent conflicts or data loss.
2. Clear browser cache. Depending on the browser you use (Chrome, Edge, Firefox), the steps vary:
   • Microsoft Edge: Open Edge, click the three dots (…) in the top-right corner, select “Settings,” then navigate to “Privacy, search, and services.” Under “Clear browsing data,” click “Choose what to clear,” select “Cached images and files,” then click “Clear now.”
   • Google Chrome: Open Chrome, click the three dots in the top-right, select “Settings,” then “Privacy and security,” click “Clear browsing data,” choose “Cached images and files,” set the time range to “All time,” then click “Clear data.”
   • Mozilla Firefox: Open Firefox, click the three lines (hamburger menu), select “Settings,” go to “Privacy & Security,” under “Cookies and Site Data,” click “Clear Data,” check “Cached Web Content,” then click “Clear.”
3. Clear Windows Store cache. Press Windows key + R to open the Run dialog, type “wsreset.exe,” and press Enter. A blank Command Prompt window will open, and after a few moments, the Microsoft Store will launch, indicating cache clearance.
4. Use Disk Cleanup to clear system cache and temporary files.:
   1. Press Windows key + S, type “Disk Cleanup,” and select the app.
   2. Choose the drive (usually C:) and click “OK.”
   3. In the Disk Cleanup window, check options like “Temporary files,” “Recycle Bin,” and “Thumbnails.”
   4. Click “OK,” then confirm by clicking “Delete Files.”
5. Clear DNS cache (optional but useful for network issues). Open Command Prompt as administrator: type “cmd” in the search bar, right-click “Command Prompt,” and select “Run as administrator.” Then type:
   ipconfig /flushdns and press Enter. You’ll see a confirmation message.
6. Clear Windows Update cache (if experiencing update issues).:
   1. Open Command Prompt as administrator.
   2. Stop the Windows Update service: type net stop wuauserv and press Enter.
   3. Stop the Background Intelligent Transfer Service: type net stop bits and press Enter.
   4. Navigate to the cache folder: type ren C:\Windows\SoftwareDistribution SoftwareDistribution.old and press Enter.
   5. Restart the services: type net start wuauserv and net start bits, pressing Enter after each.
7. Restart your computer. After completing all cache clearing steps, reboot your system to apply changes and optimize performance.

Common Mistakes

• Trying to clear caches without closing applications first, which can prevent some caches from clearing properly.
• Accidentally deleting important system files—stick to the recommended cache clearing methods.
• Forgetting to restart your PC after clearing caches, which may leave some caches still active.
• Using third-party cleaning tools that may remove essential files or cause system instability—prefer built-in tools.
• Ignoring browser-specific cache clearing, leading to persistent site loading issues.

Tips

• Regularly clear cache to maintain optimal system performance and prevent storage bloat.
• Use keyboard shortcuts (Windows key + R) for quick access to tools like wsreset.exe and Run dialog.
• Set a reminder to perform cache cleaning monthly or when you notice slowdowns.
• Combine cache clearing with disk cleanup for a thorough maintenance routine.
• Keep your Windows 10 updated to ensure cache and system management features are current and effective.

Troubleshooting

If clearing cache does not improve performance or if you encounter issues:

• Restart your PC: Sometimes, a simple reboot can resolve lingering cache or temporary glitches.
• Run system file checker: Open Command Prompt as administrator, type sfc /scannow, and press Enter. This scans and repairs corrupted system files.
• Use Windows Troubleshooter: Go to Settings > Update & Security > Troubleshoot, and run relevant troubleshooters like “Performance” or “Network.”
• Update Windows: Ensure your system is up to date, as updates often include performance improvements and bug fixes.
• Check disk health: Use tools like CHKDSK or third-party disk health checkers to identify hardware issues that might affect cache or performance.
• Reset your browser settings: If cache clearing in browsers doesn’t help, consider resetting browser settings or reinstalling the browser.

If problems persist after these steps, consider seeking professional help or visiting support forums for more tailored assistance.
