1. Disable Startup Programs
When you turn on your laptop, dozens of apps may start automatically and slow down boot time.
- Press Ctrl + Shift + Esc to open Task Manager.
- Go to Startup tab.
- Disable unnecessary programs (like Spotify, Zoom, or game launchers).
This alone can cut startup time by half.
2. Uninstall Unnecessary Software
Many laptops come with pre-installed software (bloatware) you never use.
- Open Settings > Apps > Installed Apps.
- Remove anything you don’t need.
Less clutter means faster performance.
3. Run Windows Updates
Windows regularly releases performance and security updates.
- Go to Settings > Windows Update.
- Install pending updates.
This keeps your laptop optimized and secure.
4. Check for Malware
Malware is one of the biggest reasons laptops slow down.
- Run a full scan using Windows Security.
- Or install trusted antivirus software like Malwarebytes.
Removing hidden threats can instantly speed things up.
5. Free Up Disk Space
If your drive is nearly full, Windows struggles to run smoothly.
- Open Storage Sense in Windows settings.
- Delete temporary files, cache, and recycle bin data.
Aim to keep at least 20% of your storage free.
6. Use Disk Cleanup
Windows has a built-in Disk Cleanup tool.
- Search for Disk Cleanup in the Start menu.
- Select your drive (C:).
- Delete system junk, update leftovers, and logs.
7. Defragment or Optimize Drives
If you’re using an HDD, fragmentation slows things down.
- Search Defragment and Optimize Drives.
- Run it for your hard drive.
For SSD users, Windows automatically optimizes, so no worries.
8. Upgrade to an SSD
If your laptop still runs on HDD, this is the biggest speed booster.
- SSDs load Windows and apps in seconds.
- Even an older laptop feels brand new with an SSD upgrade.
9. Add More RAM
If you multitask a lot, 4GB isn’t enough.
- Upgrade to 8GB or 16GB RAM.
- More RAM = smoother multitasking and faster apps.
10. Adjust Power Settings
Windows defaults to “Balanced” mode to save energy.
- Go to Control Panel > Power Options.
- Switch to High Performance mode.
This gives your laptop more power for speed.
11. Disable Visual Effects
Windows looks pretty with animations, but they eat resources.
- Right-click This PC > Properties.
- Click Advanced system settings > Performance Settings.
- Choose Adjust for best performance.
12. Stop Background Apps
Many apps run in the background even if you’re not using them.
- Go to Settings > Apps > Background Apps.
- Turn off unnecessary ones.
This frees up RAM and CPU usage.
13. Reset or Reinstall Windows
If nothing else works, a clean start is the way to go.
- Backup your files.
- Reset Windows from Settings > System > Recovery.
This removes junk and restores speed.
14. Keep Drivers Updated
Outdated drivers can cause lag.
- Use Device Manager to update drivers.
- Or download updates from your laptop manufacturer’s website.
15. Clean Your Laptop Physically
Dust can cause overheating, which slows performance.
- Use compressed air to clean vents and fans.
- Keep your laptop on a flat, cool surface.
Bonus Tip: Use Lightweight Software
- Switch from Chrome to Edge or Brave.
- Use lightweight apps instead of heavy ones.
Small changes like this keep your laptop responsive.
