How to Clear Cache in Windows 11 for Better Performance

Over time, your Windows 11 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 ensure that your system runs smoothly. Before you begin, it’s a good idea to close all open programs and save any ongoing work, as some cache clearing methods may require restarting your system or applications. Follow this step-by-step guide to effectively clear cache in Windows 11 and optimize your device’s performance.

What You’ll Need

• A Windows 11 PC with administrator rights
• An internet connection (for some steps involving browser cache)
• Optional: Backup important data before performing system-wide cache clearing

Step-by-Step

1. Clear Browser Cache
   1. Open your preferred web browser (Microsoft Edge, Chrome, Firefox, etc.).
   2. Access the browser’s settings menu. Usually, this is found by clicking the three dots or lines in the top-right corner.
   3. Navigate to the privacy or history section. For example, in Edge, go to Settings > Privacy, Search, and Services.
   4. Select the option to clear browsing data or history.
   5. Choose the cache or cached images and files option, along with any other data you wish to clear.
   6. Click the clear or delete button to remove the cached data.
2. Clear Windows Store Cache
   1. Press Windows key + R to open the Run dialog box.
   2. Type wsreset.exe and press Enter.
   3. A blank Command Prompt window will appear, and after a few moments, the Microsoft Store will open, indicating the cache has been cleared.
3. Clear System Cache via Disk Cleanup
   1. Click on the Start menu and type “Disk Cleanup,” then select the Disk Cleanup app.
   2. Select the drive you want to clean (usually C:) and click OK.
   3. In the Disk Cleanup window, check the boxes for Temporary files, Thumbnails, and other cache-related files.
   4. Click OK, then confirm by selecting Delete Files.
4. Clear Windows Cache Files Manually
   1. Open File Explorer (Windows key + E).
   2. Navigate to the folder C: emp or %temp% (type this in the address bar and press Enter).
   3. Select all files and folders (Ctrl + A), then delete them.
   4. Empty the Recycle Bin to permanently remove these files.
5. Clear DNS Cache
   1. Open Command Prompt as administrator: right-click the Start button and select “Windows Terminal (Admin)” or “Command Prompt (Admin).”
   2. Type ipconfig /flushdns and press Enter.
   3. You’ll see a confirmation message indicating the DNS cache has been successfully flushed.
6. Restart Your Computer
   1. Once you’ve cleared various caches, restart your Windows 11 system to ensure all changes take effect.

Common Mistakes

• Accidentally deleting important files instead of cache files—always select only cache-related data during cleanup.
• Not closing applications before clearing cache, which can prevent some caches from clearing properly.
• Ignoring the need to restart after clearing cache, which may cause old data to persist temporarily.
• Using third-party tools without verifying their safety, potentially risking malware or system instability.

Tips

• Regularly clear browser cache to maintain browsing speed and privacy.
• Use Disk Cleanup monthly to remove unnecessary system files.
• Create a system restore point before performing extensive cache clearing, just in case.
• Keep your Windows 11 system updated to ensure cache management features are optimal.
• Consider using built-in tools like Storage Sense for automatic cache management.

Troubleshooting

If clearing cache doesn’t resolve your issue or causes unexpected problems, try these steps:

• Restart your computer: Sometimes, a simple reboot clears residual cache data or resolves minor glitches.
• Run System File Checker: Open Command Prompt as administrator and type sfc /scannow. This scans and repairs corrupted system files that might be causing cache issues.
• Reset your browser settings: If browser cache clearing doesn’t work, resetting your browser to default settings can help resolve persistent problems.
• Update Windows 11: Ensure your system is running the latest updates, as patches often improve cache management and system stability.
• Use troubleshooting tools: Windows 11 offers built-in troubleshooters for network, performance, and app issues that might be related to cache problems.
