Manage Licenses and Prevent Software Conflicts
Understand your license entitlements and correctly transition to Office Pro Plus without losing your Office Home and Student 2021 purchase.
Office Home and Student 2021 is a perpetual license that is permanently linked to the Microsoft account used during your initial activation. Uninstalling this software does not remove your entitlement. You can safely uninstall it to use your university's Office Pro Plus, and reinstall your personal version later subject to Microsoft's standard device and activation rules.
It is highly recommended to avoid installing conflicting Office versions (such as Home & Student and Pro Plus) on the same computer simultaneously, as this can cause file association errors and activation conflicts.
Open 'Settings' > 'Apps' > 'Installed apps' on your Windows device, locate 'Microsoft Office Home and Student 2021', and click 'Uninstall' to remove it and prevent conflicts.
Log into your university portal or Microsoft 365 online with your student credentials, click 'Install Office', and download the setup file.
Run the downloaded setup file and follow the on-screen prompts to install Office Pro Plus. Once installed, open any app like Word and sign in with your university account to activate it.

Frequently Asked Questions
Can I have two different versions of Microsoft Office installed on the same computer?
