Question details
The user wants to remove previous Office installations, such as Office Home and Student 2021, and ensure that only their Microsoft 365 subscription is active across Word, Excel, and PowerPoint.
- Product

- Device & OS
- not provided
- Scenario
- Switching from a one-time purchase of Office to a Microsoft 365 subscription.

Ensure you have your Microsoft account login credentials handy, as you will need them to download and reactivate your Microsoft 365 subscription after the cleanup process.
Use the Microsoft Office Uninstall Support Tool
The most effective way to completely remove all traces of older Office versions and their shared components.
Because Office 2021 and Microsoft 365 share underlying components, traditional uninstallation methods might leave older license information behind. Using Microsoft's dedicated cleanup tool ensures a complete wipe.
Download and run the Microsoft Support and Recovery Assistant (Office clean uninstall tool) from the official Microsoft support website.
Select the older version of Office you want to uninstall (e.g., Office 2021 or Office 15) from the tool's interface and follow the on-screen prompts.
Restart your computer once the uninstallation tool finishes the removal process.
Log in to your Microsoft account, navigate to the 'Services and Subscriptions' page, and download the latest Microsoft 365 installer.
Open any installed Microsoft 365 application (like Word or Excel) and sign in with your Microsoft account to confirm the correct subscription is active.
Manually Uninstall Older Office Versions via Settings
Use the built-in system settings to remove the older Microsoft Office application if you prefer not to download additional support tools.

Frequently Asked Questions
Why do both Office 2021 and Microsoft 365 show up in my account?
Office one-time purchase versions (like 2021) and Microsoft 365 share many core components. When installed on the same machine or linked to the same account, the applications may display both licenses under your account information, even if only one is actively running.
Can I permanently delete an old Office product from my Microsoft account?
You can uninstall the software from your devices to resolve conflicts, but previous purchases and licenses will remain permanently listed in your Microsoft account's purchase history and 'Services and Subscriptions' page for record-keeping.
How do I verify that my Microsoft 365 subscription is the active one?
Open any Office application like Word or Excel, click on 'File', and navigate to 'Account'. Under the Product Information section, it should state 'Subscription Product Microsoft 365' to confirm it is actively handling your files.
