How to Clear Memory Cache in Windows 11 for Better Performance

Over time, your Windows 11 PC accumulates temporary files and cached data that can slow down system performance. Clearing the memory cache helps your computer run more smoothly, improves responsiveness, and can resolve minor glitches. This guide walks you through easy, step-by-step methods to clear your cache without the need for advanced technical skills. Before starting, ensure your important work is saved, as some steps may require a system restart. Clearing cache is a safe process that resets temporary data, freeing up system resources and enhancing overall performance.

What You’ll Need

  • A Windows 11 PC with administrative access
  • An internet connection (for updates or online tools, optional)
  • Basic familiarity with Windows interface

Step-by-Step

  1. Press the Windows key + R to open the Run dialog box.
  2. Type cmd and press Ctrl + Shift + Enter to run Command Prompt as an administrator. Confirm any User Account Control prompts.
  3. In the Command Prompt window, type ipconfig /flushdns and press Enter. This clears your DNS cache, which can improve web browsing.
  4. Next, type del /q /f /s %TEMP% and press Enter. This deletes temporary files stored in your system’s temp folder.
  5. If you want to clear the Windows Store cache, type wsreset.exe and press Enter. A blank Command Prompt window will open, and the cache will clear automatically.
  6. Alternatively, to clear system cache via Storage Settings, click the Start menu and select Settings (gear icon). Navigate to System > Storage.
  7. Click on Temporary files. Check the boxes next to the cache types you want to delete, such as Temporary files, Thumbnails, or Delivery Optimization Files.
  8. Click Remove files. Windows will delete the selected cache data, freeing up space and improving performance.
  9. For a more comprehensive clean, open Disk Cleanup: type Disk Cleanup in the Start menu search bar and select the app.
  10. Select your main drive (usually C:) and click OK. The tool will calculate space savings.
  11. Check the boxes next to Cached files, Temporary files, and other items you wish to delete. Click OK, then confirm by clicking Delete Files.
  12. Finally, restart your PC to complete the cache clearing process and apply all changes.

Common Mistakes

  • Deleting important system files—always stick to recommended cache and temporary folders.
  • Forgetting to restart after clearing cache, which may prevent changes from taking effect.
  • Using unreliable third-party tools that claim to clear cache but may cause system issues. Stick to built-in Windows methods.
  • Not backing up important data before performing system cleanups, though cache clearing is generally safe.

Tips

  • Perform cache clearing regularly—once a month—to keep your system running smoothly.
  • Combine cache clearing with disk cleanup and defragmentation for optimal performance.
  • Use Storage Sense in Windows 11 for automatic cache and temporary file management.
  • Keep your Windows 11 updated to ensure cache management tools work effectively.
  • Consider closing unnecessary background apps before clearing cache for better results.

Troubleshooting

If clearing cache doesn’t improve your PC’s performance, try the following:

  • Run System File Checker: open Command Prompt as administrator, type sfc /scannow, and press Enter. This repairs corrupted system files.
  • Perform a Windows Update to ensure your system has the latest performance improvements and bug fixes.
  • Check for malware or viruses that may be impacting system speed. Use Windows Security or trusted antivirus software.
  • Reset Windows 11’s performance settings or consider a system reset if issues persist.
  • If cache clearing causes errors or system instability, revert to a previous restore point or seek professional help.
