    Our Recommendation

    For most users, we recommend upgrading to either Microsoft 365 (for the best ongoing experience) or Office 2021/2024 (for a one-time purchase). Continuing to use Office 2016 after October 2025 puts your data and systems at risk.

    5

    Execute and Verify

    Install your new Office version, migrate your settings and data, and verify everything works correctly.
