1. Keep Windows 10 Updated
One of the easiest and most effective ways to boost Windows 10 performance is keeping your system up to date. Microsoft regularly releases updates that improve system stability, fix bugs, and enhance security.
Some updates also include improved drivers and performance optimizations that directly affect system speed.
How to check for updates:
- Click the Start menu
- Go to Settings → Update & Security → Windows Update
- Click Check for updates
- Install all available updates
- Restart your PC
Tip: Enable automatic updates so your PC stays optimized without manual effort.
2. Disable Unnecessary Startup Programs
Many applications automatically start when Windows boots, slowing down startup time and consuming system resources.
Disabling unnecessary startup apps can significantly speed up a slow PC.
Steps to disable startup programs:
- Press Ctrl + Shift + Esc to open Task Manager
- Go to the Startup tab
- Right-click unnecessary apps
- Select Disable
Only keep essential programs like antivirus and system drivers enabled.
3. Run the Compatibility Troubleshooter
Older programs may not be optimized for Windows 10 and can cause performance issues. The built-in Compatibility Troubleshooter automatically fixes such problems.
How to run it:
- Type Troubleshoot in the search box
- Select Troubleshoot settings
- Click Program Compatibility Troubleshooter
- Select the problematic program
- Follow on-screen instructions
This tool is especially helpful for older games and productivity software.
4. Disable Transparency & Visual Effects
Windows 10 includes several visual effects that look nice but consume system resources, especially on low-end PCs.
Disable Transparency Effects
- Go to Settings → Personalization → Colors
- Turn Transparency effects Off
Adjust Visual Effects for Best Performance
- Search for Performance
- Select Adjust the appearance and performance of Windows
- Choose Adjust for best performance
- Click Apply → OK
This can noticeably reduce lag and improve responsiveness.
5. Clean Up Disk Space & Storage
Low disk space can severely slow down Windows 10. Temporary files, cache data, and unused apps accumulate over time.
Use Storage Sense
- Go to Settings → System → Storage
- Enable Storage Sense
- Click Configure Storage Sense
Run Disk Cleanup
- Search for Disk Cleanup
- Select your system drive (C:)
- Check temporary files
- Click OK
Freeing up space improves system speed and stability.
6. Scan for Malware & Security Threats
Malware, spyware, and unwanted programs often run silently in the background, consuming CPU and memory.
Run a full scan using Windows Security:
- Open Windows Security
- Go to Virus & threat protection
- Select Scan options
- Choose Full scan
Extra protection: Tools like Malwarebytes can detect threats that Windows Defender may miss.
7. Change Power Plan for Better Performance
Windows often defaults to a balanced power plan that limits performance.
Enable High Performance mode:
- Open Control Panel
- Go to Power Options
- Select High performance
This allows your CPU and GPU to run at full potential.
8. Update Drivers for Maximum Stability
Outdated drivers can cause crashes, lag, and poor performance.
Update drivers:
- Open Device Manager
- Right-click a device
- Select Update driver
Focus on graphics, chipset, and network drivers for best results.
9. Limit Background Apps
Many apps run in the background even when you’re not using them.
- Go to Settings → Privacy → Background apps
- Turn off unnecessary apps
This saves RAM and improves battery life.
10. Hardware Upgrades That Make a Huge Difference
If software optimization isn’t enough, hardware upgrades can dramatically boost Windows 10 speed.
- Upgrade to SSD – Biggest performance improvement
- Add more RAM – Helps multitasking
- Clean dust – Prevents thermal throttling
Even an old PC can feel new with an SSD.
11. Make PC Maintenance a Habit
Regular maintenance keeps your PC running smoothly.
- Run monthly malware scans
- Clean storage every few weeks
- Install updates regularly
Consistency is the key to long-term performance.
