If your computer has been in service for a few years, you may have noticed a decline in its performance. This is a common issue, particularly with Windows 11 PCs, where background processes and unnecessary files can accumulate over time, leading to sluggishness. Fortunately, there’s no need to resort to a complete reinstallation of Windows to restore your system’s speed. Below are some straightforward and cost-effective strategies to enhance your operating system’s performance, along with a few hardware upgrade suggestions.
1. Uninstall Crapware
New computers often come pre-installed with a variety of unnecessary software, commonly referred to as bloatware or crapware. For instance, a Lenovo PC I tested previously included nearly 20 so-called helper programs that frequently interrupted my workflow. To remove these unwanted applications, right-click on any app icon in the Start menu and select Uninstall. This action will either uninstall the program immediately or direct you to the appropriate Settings page for uninstallation.
You can also access the Installed Apps section by right-clicking the Windows Start button or by typing “programs” in the search box next to the Start button. Sorting the list of installed apps by your PC maker’s name or by size can help you identify and eliminate unnecessary programs. Dedicate some time to this task, as removing multiple apps may take a while. Remember to also uninstall any applications you added yourself but no longer need.
2. Limit Startup Processes
Many programs install background processes that launch every time you start your PC, some of which may not be necessary. While earlier versions of Windows required the use of MSCONFIG to manage these processes, Windows 11 simplifies this through the Task Manager. To access it, press Ctrl-Shift-Esc and navigate to the Startup tab, where you can view all programs that load with Windows. Here, you can easily disable any applications that you rarely use, such as iTunesHelper.
3. Clean Up Your Disk
With the prevalence of SSDs, slowdowns due to storage access are less common, yet an overly full SSD can still hinder performance. To mitigate this, enable Windows’ Storage Sense, which offers automatic cleanup options for temporary files and user content. This feature can help maintain optimal storage usage and keep your system running smoothly.
4. Check for Viruses and Spyware
Viruses and spyware can significantly impact your PC’s performance. While Microsoft Defender can help detect these threats, utilizing dedicated malware removal software may yield better results. Ensure you have ongoing antivirus protection, as some solutions are lightweight and even free.
5. Change the Power Mode to Best Performance
Adjusting your power settings to Best Performance can enhance your computer’s speed, although it may increase energy consumption. Navigate to Settings > System > Power & Battery to make this change. If you’re using a laptop, connecting it to a power source can also unlock additional performance features.
6. Find and Fix Misbehaving Processes
Occasionally, certain applications may consume excessive CPU and memory resources, causing your system to lag. If you notice a slowdown, check the Task Manager (Ctrl-Shift-Esc) to identify any resource-hogging processes. You can sort the list by CPU or Memory usage to pinpoint the culprits. If a program consistently misbehaves, consider closing it or uninstalling it altogether.
7. Keep Windows Up-to-Date
Windows typically installs updates automatically, but it’s wise to check periodically by going to Settings > Windows Update. Updates can include essential system software and hardware driver enhancements that improve performance. You can also schedule updates for times when you won’t need your PC.
8. Run Troubleshooters
To identify and resolve issues, search for “troubleshoot” in the Start menu. Windows provides various troubleshooting utilities that can be run automatically or manually. Additionally, consider running maintenance tasks from the Control Panel to ensure your system remains in good health.
9. Install and Run Microsoft PC Manager
Microsoft offers a utility called PC Manager, designed to optimize your PC’s performance with a single click. This tool consolidates several performance-enhancing features and includes a RAM cleanup function, which may help improve your system’s speed.
10. Add More RAM (If You Can)
While Windows 11 manages memory more efficiently than its predecessors, increasing your RAM can still enhance performance. Major brands like Corsair and Kingston provide tools to help you determine the right type of RAM for your system. However, not all devices allow for RAM upgrades, especially modern ultrabooks and convertibles.
11. Install an SSD Startup Drive
For faster application launches and improved startup times, consider installing an SSD. Moving demanding applications to an SSD can significantly enhance performance. If your PC lacks an SSD, an external SSD connected via USB 3.0 or Thunderbolt can still provide a noticeable speed boost.
12. Change the System Appearance in Performance Options
Adjusting your system’s appearance settings can help speed up older PCs. Access this option by searching for adjust appearance in the Start menu. You can choose to optimize for Best Performance, which disables visual effects, or selectively disable features you can do without.
13. Keep Your PC Cool
Overheating can cause your computer to throttle its performance to prevent hardware damage. Ensure that your PC has adequate airflow and that fans are unobstructed. Regularly cleaning dust from your computer can also help maintain optimal cooling.
14. Turn Off Search Indexing
For lower-powered PCs, disabling search indexing can free up system resources. To modify indexing settings, open the Indexing Options Control Panel and adjust the locations being indexed.
15. Turn Off Tips and Notifications
Disabling Windows’ Tips feature can reduce processing demands on your system. Similarly, managing notifications can help alleviate slowdowns, particularly during gaming or full-screen applications. Adjust these settings in System > Notifications within the Settings app.
16. A Bonus for Gamers: Game Mode and Other Game Settings
Windows 11 includes a Game Mode that optimizes performance during gaming sessions by limiting background tasks and preventing updates. You can enable this feature in Settings > Gaming. Additionally, consider adjusting the Optimizations for Windowed Games setting to enhance gaming performance further.
