Is your Windows 11 PC feeling sluggish or unresponsive? Over time, various factors can cause your system to slow down, impacting productivity and overall experience. Fortunately, there are practical steps you can take to speed up Windows 11, improve responsiveness, and enjoy a smoother computing experience.

   • Follow prompts to remove any threats found
9. Upgrade Hardware if Needed: If your PC still runs slowly, consider adding more RAM or switching to an SSD for faster data access.

Common Mistakes

• Disabling essential services or drivers, which can cause system instability
• Ignoring malware or security threats, leading to performance issues
• Overloading startup with unnecessary programs without reviewing their necessity
• Neglecting to update Windows and drivers regularly
• Over-optimizing visual effects to the point of affecting usability

Tips

• Regularly perform disk cleanup and defragmentation to maintain speed

• Limit background processes and apps running in the background
• Consider resetting Windows if performance issues persist after troubleshooting

Troubleshooting

If your PC remains slow despite following these steps, try the following troubleshooting tips:

• Boot into Safe Mode: This helps determine if third-party software is causing the slowdown.
  • Press Win + R, type msconfig, and hit Enter
  • Navigate to the Boot tab and check Safe boot

  • Open Command Prompt as administrator

  • Wait for the scan to complete and follow any instructions
• Reset Windows 11: As a last resort, reset your system to factory settings, keeping your files or performing a clean install.
