How to Upgrade from Office Home to a Microsoft 365 Subscription

Office Home is a perpetual desktop license, while Microsoft 365 is a subscription tied to an account and plan. There is no in-app conversion switch: compare the available Microsoft 365 plans, purchase the appropriate subscription with the account you intend to keep, install or sign into the included apps, and verify activation before removing the existing Office installation.

FAQs About Upgrade from Office Home to a Microsoft 365 Subscription

Do I need to uninstall my old Office Home software before upgrading to Microsoft 365?

Yes, for the most stable transition. Before purchasing your new subscription, open your Windows Settings, go to "Apps," locate your current Office Home installation, and select "Uninstall." This prevents license conflicts when you download the new Microsoft 365 installer from your account dashboard.

Will I lose my local documents when I upgrade my subscription?

No. Your local files saved on your hard drive (like .docx and .xlsx files) remain completely unaffected by the upgrade process. Once you complete the steps for upgrade from Office Home to a Microsoft 365 Subscription and install the new applications, you can open your existing files exactly as before.

How do I apply the new Microsoft 365 subscription to my existing Microsoft account?

You must ensure you are logged into the exact same Microsoft account tied to your Windows profile. Go to the Microsoft 365 upgrade page, click "Buy Now" on your chosen plan, and complete the transaction. The new license will automatically bind to your existing email address, overriding the legacy Office Home limitations.

Can I convert a remaining Office Home license into Microsoft 365 subscription time?

No. Because Office Home is a one-time perpetual purchase rather than a time-based subscription, Microsoft does not offer pro-rated credits or time conversions. You will simply retain the right to use the old software on an older machine, while your new subscription dictates your active cloud services.
