Is your Windows 11 PC running slower than it used to? You’re not alone. Many users experience lag and reduced performance over time. The good news? You don’t have to spend money on expensive hardware upgrades. With a few software tweaks and system optimizations, you can significantly boost your PC’s speed.

Windows 11, though sleek and efficient, still requires regular maintenance to perform at its best. Whether you’re dealing with background apps or cluttered storage, there are plenty of ways to restore your system’s responsiveness. In this guide, we’ll explore smart, effective methods to speed up your PC and enhance overall performance using built-in features and free tools. Let’s dive in and learn how to optimize your system using performance tips and system cleanup.
1. Disable Startup Programs for Faster Boot Times
One of the main reasons for a slow boot is too many startup apps. These apps launch every time you power up. They consume memory and resources before you even begin work.
To manage startup apps:
- Press
Ctrl + Shift + Esc
to open Task Manager. - Go to the Startup tab.
- Disable any app you don’t need immediately after startup.

More details can be found on Microsoft’s support page.
2. Uninstall Unnecessary Apps and Bloatware
Over time, we install software we no longer use. These unused apps can slow your system and take up storage.
Go to:
Settings > Apps > Installed Apps
- Remove apps you don’t recognize or use.
You can also use third-party uninstallers like Revo Uninstaller for a more thorough cleanup.
3. Use Disk Cleanup and Storage Sense
Temporary files, old updates, and cached data can clog your system. Windows 11 offers built-in tools to clear this junk.
Enable Storage Sense:
Settings > System > Storage > Storage Sense
- Set it to run automatically.
You can also run Disk Cleanup manually:
- Type Disk Cleanup in the Start menu.
- Select the drive and remove unnecessary files.

4. Adjust Visual Effects for Better Performance
Windows 11 includes animations and visual effects that look great but can slow things down. Reducing these can improve performance.
To do this:
- Press
Windows + R
, typesysdm.cpl
, hit Enter. - Go to the Advanced tab, then click Settings under Performance.
- Select “Adjust for best performance” or customize as needed.

5. Optimize Your Drives
Fragmented data can make your system sluggish. Though Windows 11 handles this automatically, manual checks help.
Here’s how:
- Type Defragment and Optimize Drives in the Start menu.
- Analyze and optimize each drive.
Note: SSDs don’t need defragmentation but benefit from optimization.

6. Disable Background Apps
Background apps often run unnoticed and drain system resources. Disabling them can free up memory and CPU usage.
Go to:
Settings > Apps > Installed apps
- Select an app, click Advanced options, and set Background apps permissions to Never.
This simple step improves speed without affecting essential functions.
7. Keep Windows and Drivers Updated
Outdated software often leads to performance issues. Updates usually contain bug fixes and performance enhancements.
To check for updates:
Settings > Windows Update
- Install any pending updates.
For drivers:
- Visit your manufacturer’s website.
- Or use Intel’s Driver & Support Assistant to update relevant components.
8. Manage Power Settings
Windows 11 includes different power plans. Choosing the right one can make a noticeable difference in performance.
To switch plans:
Settings > System > Power & Battery > Power Mode
- Select Best Performance for maximum speed.
This is especially useful for laptops connected to a power source.
9. Use a Lightweight Antivirus
Heavy security suites can slow down your PC. Consider switching to a lightweight antivirus program like Bitdefender Free.

Windows Security is also a good built-in option that works well with the OS.
10. Reset Your PC as a Last Resort
If nothing else works, a system reset might be necessary. This will reinstall Windows without affecting your files (optional).
Go to:
Settings > System > Recovery
- Click Reset this PC and choose your preferred option.
This clears out all clutter and gives your system a fresh start.
