Uninstall the Trial and Reinstall Office Professional

Press the Windows key, type 'Apps and Features' in the search bar, and press Enter to open the system settings.
Scroll through the application list to find 'Microsoft Office 365' or 'Microsoft Office Home'. Click on the application and select 'Uninstall'.
Open your web browser and navigate to account.microsoft.com/services. Log in using the Microsoft account associated with your Office Professional license.
Locate your Office Professional purchase in the account dashboard and click 'Install' to download and run the correct setup file.
Use Microsoft Support and Recovery Assistant
Use Microsoft's official tool to deeply clean corrupted or stubborn Office license files and trial versions if standard uninstallation fails.

Frequently Asked Questions
Why does Windows automatically install Office Home or 365?
Many new Windows installations or manufacturer system images come with a pre-installed trial of Office 365 Family or Office Home. If you don't manually remove it before installing your Professional version, Windows may default to the trial license.
Can I have both Office Home and Office Professional installed?
No, installing multiple versions of Microsoft Office on the same Windows device often causes severe license conflicts, resulting in activation errors or the system defaulting to the lowest tier.
How do I check which Microsoft account holds my Professional license?
Visit account.microsoft.com/services and log in with any email addresses you might have used during purchase. The correct account will list your Office Professional product under the 'Products and subscriptions' section.
