2
Open Windows Settings

Click the Start menu on your computer and navigate to Settings > Apps > Installed apps.

3
Uninstall the trial

Frequently Asked Questions

Do I absolutely have to uninstall Microsoft 365 before installing Office Home & Student?

Yes, it is highly recommended. Having both versions installed simultaneously often causes activation conflicts, default app errors, and persistent prompts to subscribe to Microsoft 365.

Will uninstalling the Microsoft 365 trial delete my saved documents?

No, uninstalling Microsoft 365 only removes the application software from your device. All your saved documents, spreadsheets, and presentations will remain safe on your hard drive.

How do I know if my Office Home & Student license is active?

You can verify your license status by logging into your Microsoft account at account.microsoft.com/services. Your purchased products and their current activation status will be clearly listed there.
