Uninstall the Microsoft 365 Trial and Install Office Home & Student
Removing the preinstalled trial version before installing your purchased license is the most effective way to prevent activation and installation conflicts.
Many new computers come with a pre-installed trial of Microsoft 365. If you try to install a perpetual license like Office Home & Student without removing the trial first, the system may struggle to determine which license to activate.
Go to https://account.microsoft.com/services in your web browser and log in with your Microsoft account to verify that your Office Home & Student purchase is successfully linked.
Click the Start menu on your computer and navigate to Settings > Apps > Installed apps.
Scroll through the app list to find the preinstalled Microsoft 365 software. Click the three-dot menu icon next to it and select Uninstall. Follow the prompts to completely remove it.
Return to your Microsoft account services page (account.microsoft.com/services), locate your Office Home & Student license, and click the Install button. Run the downloaded setup file to complete the installation.

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.
