Question details
The user needs to recover and reinstall their perpetual (one-time purchase) Office license after it was overridden by a Microsoft 365 subscription or trial.
- Product
- Microsoft Office
- Device & OS
- not provided
- Scenario
- Reverting from a Microsoft 365 trial or active subscription back to a previously purchased one-time Office license (like Office 2021 or 2024).
- Observed behavior

Ensure you have the login credentials (email address and password) for the specific Microsoft account that was originally used to purchase or redeem your one-time Office license.
Uninstall Microsoft 365 and Reinstall Your Perpetual License
This is the primary method to resolve licensing conflicts by removing the subscription version and reinstalling your purchased one-time Office edition from your Microsoft account.
Windows computers often come with a pre-installed trial of Microsoft 365, which can conflict with or override older perpetual licenses (like Office 2021 or 2024). You must completely remove the trial before reinstalling your purchased software.
Navigate to Windows Settings > Apps > Installed apps. Scroll down to find 'Microsoft 365', click the three dots next to it, and select 'Uninstall'.
Open your web browser and visit https://account.microsoft.com/services. Sign in with the Microsoft account associated with your perpetual Office license.
Look under the 'Services & subscriptions' section. You should see your one-time purchase, such as Office Home & Student 2021 or Office 2024, listed here.
Click the 'Install' button next to your perpetual license. Follow the on-screen prompts to download the installer, then run the setup file to complete the installation.
Verify Alternate Accounts or Contact Support
Use this solution if your perpetual license does not appear in the 'Services & subscriptions' dashboard of your primary Microsoft account.

Frequently Asked Questions
Why did Microsoft 365 replace my one-time Office license automatically?
New computers often include a pre-installed Microsoft 365 trial. If Windows updates or you accidentally activate the trial prompt, it can override your older, perpetual Office installation and change your file associations.
Will I lose my files if I uninstall Microsoft 365?
No. Uninstalling the Microsoft 365 software only removes the application itself. All your locally saved documents, spreadsheets, and presentations will remain safely on your computer.
Can I have both a perpetual Office license and Microsoft 365 installed at the same time?
It is highly discouraged. Having both installed simultaneously often causes conflicts, where files open in the wrong version and prompt you with persistent subscription activation warnings.
