Built-in vs Third-Party Utilities

Built-in Utilities (Operating System)

Modern operating systems include many essential utilities:

Windows Built-in Utilities:

  • Disk Cleanup, Defragmenter
  • Windows Defender (antivirus)
  • Task Manager
  • Backup and Restore

macOS Built-in Utilities:

  • Disk Utility
  • Activity Monitor
  • Time Machine
  • FileVault (encryption)

Third-Party Utilities

Advantages of third-party utilities:
