Disable background functionality for apps like Xbox, Weather, Skype, and others you don’t use actively.
7. Clean Up Disk Space
Keeping your hard drive clean is essential for smooth performance. Disk clutter, such as temporary files, cache, error logs, and update leftovers, can slow down file indexing and other processes.
You can clean disk space using:
- Disk Cleanup Tool
- Search for “Disk Cleanup” from the Start Menu.
- Select the drive you want to clean.
- Choose file types to delete like:
- Temporary files
- Delivery optimization files
- Recycle Bin
- Previous Windows installations
- Or through Settings > Storage > Temporary Files
Regularly cleaning your drive prevents data fragmentation and enhances performance.
8. Defragment and Optimize Drives
If you’re using a mechanical hard drive (HDD), defragmenting can significantly improve performance. Defragmentation reorganizes data to allow faster read/write operations.
To defragment:
- Open Defragment and Optimize Drives from the Start Menu.
- Select your HDD and click Optimize.
Note: If you’re using an SSD, Windows 11 already handles optimization automatically—manual defragmentation is not needed and not recommended.
9. Update Windows and Drivers
Outdated system files and device drivers can cause performance bottlenecks, compatibility issues, and crashes. Keeping your system up to date ensures you benefit from performance improvements, bug fixes, and security enhancements.
To check for updates:
- Go to Settings > Windows Update and click Check for updates.
To update drivers:
