2. Uninstall Unused Programs​

Too many apps slow down your system. Go to Control Panel > Programs > Uninstall a program and remove apps you no longer need.

3. Run Disk Cleanup​

Disk Cleanup removes temporary files that waste space.

Win + S → search “Disk Cleanup” → select your drive → clean system files

4. Check for Malware​

Install a trusted antivirus like:

• Microsoft Defender (built-in)
• Bitdefender
• Malwarebytes

Tip: Don’t forget to keep your antivirus updated.

5. Keep Drivers and Windows Updated​

Old drivers can cause hardware glitches. Always update through:

Start > Settings > Windows Update > Check for updates

6. Use Lightweight Software​

Avoid resource-heavy tools. Here are better alternatives:

• VLC instead of Windows Media Player
• LibreOffice instead of MS Office (for light use)
• Brave browser instead of Chrome (less RAM usage)

7. Organize and Backup Your Files​

Cluttered files = slow performance. Sort documents into folders and consider OneDrive or an external drive for backup.

8. Scan Disk Health​

Use the CHKDSK command to scan your disk.

chkdsk C: /f /r

Or use tools like CrystalDiskInfo to monitor SSD/HDD health.

9. Defragment (For HDDs Only)​

If you're still using an HDD, run defrag:

Win + S → search “Defragment and Optimize Drives”

Tip: SSDs don’t need defragmentation.

10. Monitor Startup Programs​

Too many startup apps slow down boot time.

Ctrl + Shift + Esc → Startup tab → Disable unnecessary apps
