Performance Optimization: How to Make Your PC Fly in 2026

Many programs promise to "accelerate your PC with one click," but most are just marketing. Real optimization consists of removing what's not used and ensuring Windows doesn't limit your hardware's power. In 2026, with the heavier Windows 11, these manual adjustments are the difference between a PC that "drags" and one that responds instantly.

Windows transparency and animations consume your GPU cycles. Let's disable them:

1. Search for 'Adjust the appearance and performance of Windows'.
2. Select 'Adjust for best performance'.
3. Check only: 'Smooth edges of screen fonts' and 'Show thumbnails instead of icons' so it's not too ugly.
4. Click Apply. Windows will feel much snappier now.

Windows usually defaults to 'Balanced' mode to save energy. If you want full power:
Go to Control Panel > Hardware and Sound > Power Options. Choose 'High Performance'. If you have a high-end desktop, you can also enable 'Ultimate Performance' via CMD.

🧠 Windows AI Intelligence

Windows 11 uses AI to predict what you'll use and pre-loads it in the background. This consumes RAM and CPU:

1. Open the Windows Registry (type 'regedit' in the Start menu).
2. Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System
3. Create a new DWORD value named EnableActivityFeed and set it to 0.
4. Look for HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
5. Create a new DWORD value named EnableCdp and set it to 0.

🧹 Deep Disk Cleanup

Windows accumulates junk over time. Use Disk Cleanup and advanced commands:

1. Open Disk Cleanup as administrator and check all options, including 'Device driver packages'.
2. Open Command Prompt as administrator and run:

   dism /online /cleanup-image /spsuperseded

   sfc /scannow

   chkdsk C: /f /r

3. For SSDs: Ensure TRIM is active and disable scheduled defragmentation:
   • Open 'Defragment and Optimize Drives'
   • Click 'Change settings' and uncheck 'Run on a schedule'
   • Manually 'Optimize' to trigger the TRIM command

🧠 RAM Management

Virtual memory helps when physical RAM is full. Configure it for ideal performance:

1. Press Win + R, type sysdm.cpl and press Enter.
2. Go to 'Advanced' → 'Performance' → 'Settings'.
3. In the 'Advanced' tab, click 'Virtual Memory' → 'Change'.
4. Uncheck 'Automatically manage paging file size'.
5. Select your SSD and choose 'System managed size' or set a custom 4GB-8GB range.
6. Click 'Set' and 'OK'. Restart your computer.

⚡ SysMain (Superfetch)

SysMain preloads apps into RAM. On modern NVMe SSDs, this can sometimes cause unnecessary stuttering:

1. Press Win + R, type services.msc and press Enter.
2. Look for SysMain.
3. Right-click → Properties.
4. Change 'Startup type' to 'Disabled'.
5. Click 'Stop' and then 'OK'.

🎮 Windows Game Mode

Windows 11 has a Game Mode that prioritizes resources for gaming:

1. Go to Settings > Gaming > Game Mode.
2. Turn it ON.
3. In 'Graphics' settings, enable Hardware-accelerated GPU scheduling.
4. This reduces CPU overhead and improves frametimes in modern titles.

🔧 GPU Power Settings

1. NVIDIA: Open NVIDIA Control Panel → Manage 3D Settings.
   • Set 'Power management mode' to 'Prefer maximum performance'
   • Set 'Low Latency Mode' to 'On' or 'Ultra'
2. AMD: Open Radeon Software → Performance → Tuning.
   • Set the Power Profile to 'Performance'
   • Disable 'Power Efficiency' toggles

🛡️ Windows Defender Exclusions

The built-in antivirus can slow down game loading. Add exclusions for your game folders:

Go to Windows Security > Virus & Threat Protection > Manage settings > Add or remove exclusions. Add your Steam/Epic Games folders here. (Warning: Only do this for trusted game directories).
