How to Clear Computer Cache on Windows 10 for Better Performance

Over time, your Windows 10 computer accumulates cache files that can slow down performance, cause glitches, or prevent updates from installing correctly. Clearing your cache helps your system run smoother, frees up storage space, and can resolve common issues. Before you begin, ensure you have administrator privileges on your Windows account, as some steps may require elevated permissions. Also, note that clearing cache might temporarily log you out of websites or reset some app settings, so make sure you remember your login details and preferences.

What You’ll Need

• Windows 10 PC with administrator access
• Internet connection (for certain cache types)
• Basic familiarity with navigating Windows settings

Step-by-Step

1. Press the Windows key + R to open the Run dialog box.
2. Type “%temp%” and press Enter. This opens the folder containing temporary files.
3. Select all files in the folder by pressing Ctrl + A.
4. Press Delete on your keyboard, then confirm when prompted to delete temporary files.
5. Repeat the process for the prefetch folder by typing “prefetch” in the Run box and deleting its contents.
6. Open the Settings app by clicking the Start menu and selecting Settings (gear icon).
7. Navigate to Privacy > Storage, then click on “Temporary files” or “Free up space now” under Storage Sense.
8. Check the boxes next to cache files, temporary internet files, and other items you wish to delete.
9. Click “Remove files” to clear selected caches.
10. For browser cache, open your preferred browser (e.g., Chrome, Edge, Firefox).
11. Access the browser’s settings menu, find the Privacy or History section, and select “Clear browsing data”.
12. Choose the time range (e.g., All time) and ensure “Cached images and files” is checked.
13. Click “Clear data” or “Clear browsing history” to complete the process.
14. Optionally, use dedicated cleaning tools like Disk Cleanup: open the Start menu, type “Disk Cleanup,” and select the app.
15. Select the drive you want to clean (usually C:) and click OK.
16. Check boxes for cache and temporary files, then click “OK” and confirm to delete.

Common Mistakes

• Deleting essential system files—only delete cache and temporary files, not system or program files.
• Not closing browsers or apps before clearing cache—this can prevent files from deleting properly.
• Using inappropriate tools—stick to built-in Windows tools or trusted third-party cleaners.
• Ignoring browser cache—each browser manages its cache separately, so clear each one individually.
• Overlooking backup—if you’re unsure, back up important data before deleting cache files.

Tips

• Set up Storage Sense in Windows 10 to automatically clear cache and temporary files regularly.
• Use keyboard shortcuts (Win + R) for quick access to system folders.
• Regularly clearing cache can improve startup times and overall system responsiveness.
• Keep your browsers and Windows updated to ensure cache clearing tools work effectively.
• Consider using third-party tools like CCleaner for more comprehensive cache cleaning, but only from reputable sources.

Troubleshooting

If clearing cache does not improve performance or if you encounter errors, try the following:

• Restart your computer after clearing cache to ensure changes take effect.
• Run a system scan using Windows Defender or your preferred antivirus software to check for malware that might interfere.
• Use the built-in System File Checker tool: open Command Prompt as administrator, type “sfc /scannow,” and press Enter.
• If specific browsers are not clearing cache, check their individual settings or reinstall the browser.
• Ensure no background processes are preventing cache files from deleting—use Task Manager to end unnecessary processes.
• If persistent issues remain, consider performing a Windows Reset or clean installation, but back up your data first.

Frequently Asked Questions

2. How often should I clear my cache?

It’s recommended to clear cache every few months or if you notice your system slowing down. Regular maintenance helps keep your computer running smoothly.

3. Is it safe to use third-party cache cleaners?

Yes, but only use reputable tools like CCleaner from trusted sources. Avoid unreliable software that may contain malware or delete important files.

4. Will clearing cache improve my internet speed?

5. Can I automate cache clearing in Windows 10?

6. What is the difference between temporary files and cache?

Temporary files are created by Windows and apps for short-term use, while cache stores data to speed up access to frequently used resources. Clearing both can free up space and improve performance.

By following these steps and tips, you can effectively clear your Windows 10 cache, optimize your system’s speed, and resolve common performance issues. Regular maintenance ensures your computer remains responsive and clutter-free, providing a smoother user experience over time.
