Fixing lag on a Windows 11 PC can significantly boost your computer’s performance and make your overall experience smoother. By following these steps, you will optimize your system settings, clean up unnecessary files, and ensure your hardware drivers are up to date. Let’s dive in to make your PC run like a well-oiled machine.

Step-by-Step Tutorial: How to Fix Lag on PC Windows 11

In this section, we will guide you through specific steps to reduce lag on your Windows 11 PC. Each step will help you address different aspects of your system that could be causing the lag.

Step 1: Update Windows and Drivers

Go to Settings > Update & Security > Windows Update, and click "Check for updates."

Keeping your Windows and drivers updated ensures that your system has the latest performance improvements and bug fixes. This step is crucial as outdated software can cause lag and other performance issues.

Step 2: Disable Startup Programs

Press Ctrl + Shift + Esc to open Task Manager, go to the Startup tab, and disable unnecessary programs.

Many programs automatically start when you boot up your PC, which can slow down your system. By disabling these unnecessary startup programs, you can improve your computer’s boot time and overall performance.

Step 3: Adjust Visual Effects

Right-click on This PC, select Properties > Advanced system settings, go to the Performance section, and click Settings. Then choose "Adjust for best performance."

Windows 11 comes with many visual effects that, while pretty, can consume system resources. Adjusting these settings can help free up resources and make your PC run faster.

Step 4: Clean Up Disk Space

Open Disk Cleanup by typing it into the search bar, and select the drive you want to clean. Check the boxes for the types of files you want to delete, and click OK.

Over time, your PC accumulates a lot of unnecessary files that can clog up your storage. Disk Cleanup helps free up space, making your system more efficient.

Step 5: Scan for Malware

Use Windows Security or a trusted third-party antivirus to perform a full system scan.

Malware can seriously affect your PC’s performance. Regularly scanning for and removing any malware can help keep your system running smoothly.

Step 6: Upgrade Your Hardware

Consider upgrading your RAM or switching to an SSD for faster performance.

If you’ve tried all the software fixes and your PC is still lagging, it might be time to look at your hardware. Upgrading your RAM or moving from an HDD to an SSD can provide a significant boost in performance.

After completing these steps, your PC should run more smoothly and efficiently. You’ll notice a quicker response time and less lag, improving your overall computing experience.
