Frequently Asked Questions

Why does Office 2016 still show up after I purchased Microsoft 365?

This typically occurs because the old Office 2016 license keys and application data are still cached in your computer's registry. This tricks the system into displaying the older version identity even after the new Microsoft 365 apps are installed on your device.

Will I lose my files if I completely uninstall Office 2016 and Microsoft 365?

No, uninstalling Office applications only removes the software programs themselves. Your personal documents, spreadsheets, and presentations saved on your local hard drive or OneDrive will remain completely safe and untouched.

How do I ensure my system doesn't reinstall Office 2016 by mistake?

To prevent reverting to an older version, always install your Office suite directly from the Microsoft 365 portal while signed in with the specific account that holds your active subscription, rather than using old installation discs or offline installers.
