How to Clear Cache in Windows 11 for Better Performance

Over time, your Windows 11 PC can accumulate unnecessary cache files that slow down your system, cause glitches, or hinder performance. Clearing cache regularly helps maintain optimal speed, frees up storage space, and ensures smoother operation. This guide walks you through simple, effective steps to clear cache on Windows 11, whether you’re clearing system cache, browser cache, or application data. Before starting, ensure you have administrator privileges on your PC, as some steps require elevated permissions. Also, back up important data if necessary, though clearing cache generally doesn’t affect personal files.

What You’ll Need

• Windows 11 PC with administrator access
• Internet connection (for some steps involving browser cache)
• Optional: Disk cleanup tool (built-in)

Step-by-Step

1. Close all running applications: Before clearing cache, close all open programs to prevent conflicts or data loss.
2. Open Settings: Click the Start menu, then select the gear icon or press Windows + I to open Settings.
3. Navigate to Storage Settings: In Settings, click on ‘System’ in the sidebar, then select ‘Storage’ from the options.
4. Use Storage Sense or Manual Cleanup: Turn on ‘Storage Sense’ for automatic cache cleanup, or click ‘Temporary files’ to manually select cache types to delete.
5. Clear Temporary Files: In the ‘Temporary files’ section, check boxes for cache types you want to clear, such as ‘Temporary files,’ ‘Recycle Bin,’ and ‘Thumbnails.’ Click ‘Remove files’ to delete.
6. Clear Browser Cache: Open your preferred web browser (Edge, Chrome, Firefox). For Edge, go to Settings > Privacy, search, and services > Clear browsing data. Select ‘Cached images and files’ and click ‘Clear now.’ For Chrome, go to Settings > Privacy and security > Clear browsing data. Choose ‘Cached images and files’ and confirm.
7. Clear Windows Store Cache: Press Windows + R, type ‘wsreset.exe,’ and press Enter. A command prompt window will open, and the Store cache will reset automatically.
8. Clear DNS Cache (Optional for Network Performance): Open Command Prompt as administrator (Right-click Start > Windows Terminal (Admin)). Type ‘ipconfig /flushdns’ and press Enter. This clears DNS resolver cache, potentially resolving network issues.
9. Clear Prefetch Files (Advanced): Navigate to C:\\\Windows\\Prefetch, select files, and delete them. Note: This step is optional and should be done cautiously, as it may affect startup performance temporarily.
10. Use Disk Cleanup Tool (Optional): Search for ‘Disk Cleanup’ in the Start menu, select it, choose your drive (usually C:), and check ‘Temporary files’ and other cache-related options. Click ‘OK’ to delete.

Common Mistakes

• Deleting important system files: Only delete cache and temporary files; avoid removing system files that may affect stability.
• Clearing cache without understanding: Not all cache needs frequent clearing. Focus on temp files and browser caches unless experiencing issues.
• Ignoring browser cache: Browsers store a lot of data; forgetting to clear it can leave some performance issues unresolved.
• Using third-party cleaning tools without caution: Some tools may delete critical files or cause system issues. Stick to built-in options or reputable tools.

Tips

• Schedule regular cache cleanups using Storage Sense to automate maintenance.
• Clear browser cache periodically, especially if websites load slowly or display outdated content.
• Restart your PC after clearing cache to ensure all changes take effect properly.
• Combine cache clearing with disk cleanup for comprehensive system optimization.
• Keep your Windows 11 updated to benefit from performance improvements and bug fixes.

Troubleshooting

If clearing cache does not improve performance or causes issues:

• Restart your PC to ensure all cache clearing changes are applied.
• Check for Windows updates and install any pending updates, as these can fix bugs and improve performance.
• Run the System File Checker tool: Open Command Prompt as administrator, type ‘sfc /scannow,’ and press Enter. This scans and repairs corrupted system files.
• Perform a disk cleanup and consider resetting your PC if persistent issues remain, but back up data first.
• If browser cache clearing does not resolve browsing issues, try resetting browser settings or reinstalling the browser.
