Advanced Power Settings:
- Click "Additional power settings" then "Change plan settings"
- Select "Change advanced power settings"
- Adjust processor power management to maintain higher minimum states
- Configure hard disk timeout settings to prevent unnecessary spin-down

6. Clean Up Storage and Temporary Files

Over time, Windows 11 accumulates temporary files, update remnants, and other digital clutter that can slow down system performance.

Storage Sense Automation:
- Go to Settings > System > Storage
- Enable Storage Sense to automatically free up space
- Configure cleanup frequency and what files should be removed

Manual Cleanup Tools:
- Use Disk Cleanup (cleanmgr.exe) to remove system files and previous Windows installations
