| Feature | Office 2007 | Modern Office (365 / 2021) | | :--- | :--- | :--- | | Cost | Free (if already owned) or $20 (used) | $70/year or $150 one-time | | Real-time Co-authoring | ❌ No | ✅ Yes | | Cloud Save (OneDrive) | ❌ No | ✅ Yes | | Dark Mode | ❌ No | ✅ Yes | | Security Updates | ❌ None (high risk) | ✅ Weekly | | New File Formats (ODF, PDF round-trip) | ❌ Limited | ✅ Full | | Speed on Old PC | ✅ Very fast | ❌ Slow |

If you possess a valid retail product key, you can try:
