Weekly Tasks
These quick tasks take just a few minutes and make a big difference over time.
- Restart your computer (if you leave it on all the time)
- Check for and install Windows or macOS updates
- Empty the Recycle Bin or Trash
- Clear your browser's cache and temporary files
Monthly Tasks
Set a reminder to do these tasks once a month.
- Run a full malware scan with Windows Defender or Malwarebytes
- Check available disk space (aim to keep at least 15% free)
- Review and uninstall programs you no longer use
- Check that your backup is working properly
- Clean the outside of your computer with a soft, dry cloth
- Check for updates for your installed programs
Every 3–6 Months
These tasks are less frequent but important for long-term health.
- Clean the keyboard (compressed air works well)
- Check that your antivirus subscription is current
- Review your startup programs and disable any you don't need
- Check your hard drive's health (Windows: use CrystalDiskInfo; Mac: use Disk Utility)
- Review your passwords and update any that are weak or reused
- Test your backup by restoring a file
Tip: Use compressed air to blow dust out of your keyboard and laptop vents. Dust buildup is a major cause of overheating, which shortens your computer's lifespan.
Annual Tasks
Once a year, do a more thorough review of your computer's health and security.
- Review all installed programs and remove anything you don't use
- Check whether your operating system is still supported by the manufacturer
- Review your backup strategy and make sure it covers all important files
- Consider a professional tune-up if performance has declined
- Check whether your router's firmware is up to date
- Review your privacy settings in Windows or macOS
Physical Maintenance
Don't forget the physical side of computer maintenance:
- Keep liquids away from your computer
- Use a surge protector to protect against power spikes
- Keep the area around your computer well-ventilated
- For laptops: avoid using them on soft surfaces (beds, couches) that block the vents
- Clean the screen with a microfiber cloth — never paper towels or household cleaners
- For desktops: open the case once a year and blow out dust with compressed air
