If your Windows 11 Computer is Slow, there are several steps you can take to improve its performance. Here are some potential solutions:

  1. Restart your computer: Sometimes, a simple restart can resolve performance issues by clearing temporary files and freeing up system resources.
  2. Check for malware: Run a full scan using reliable antivirus software to check for any malware or malicious programs that could be impacting your computer’s performance. Remove any threats that are detected.
  3. Update Windows: Make sure your Windows 11 operating system is up to date. Microsoft regularly releases updates that include performance improvements and bug fixes. To update Windows, go to Settings > Windows Update and click on “Check for updates.”

  5. Optimize storage: If your computer is running low on disk space, it can affect performance.

Go to Settings > System > Storage to access these tools.
  6. Disable visual effects: Windows 11 includes various visual effects that can consume system resources. Disabling or reducing these effects can improve performance.

  7. Adjust power settings: Windows power settings can affect your computer’s performance. Ensure that your power plan is set to “Balanced” or “High performance” by going to Settings > System > Power & sleep.
  8. Update device drivers: Outdated or incompatible device drivers can cause performance issues. Visit your computer manufacturer’s website or use third-party driver update software to check for and install the latest drivers for your hardware components.
  9. Perform a disk cleanup: Use the built-in Disk Cleanup utility to remove temporary files, system files, and other unnecessary items from your computer. To access Disk Cleanup, type “Disk Cleanup” in the Windows search bar, select the drive you want to clean up, and follow the prompts.
  10. Increase virtual memory: In some cases, low virtual memory can impact performance.
