Frequently Asked Questions

Why am I getting a shared computer activation error on a personal PC?

This error typically occurs when Microsoft 365 registry keys, cached organizational credentials, or previous work/school licenses conflict with your personal Microsoft account on your Windows device.

Will running an Online Repair delete my Word or Excel files?

No, repairing Microsoft Office via the Control Panel only fixes the application files and registry settings. Your personal documents, spreadsheets, and presentations will not be deleted or modified.

What should I do if the shared computer error persists after repairing?

If repairing and clearing credentials doesn't work, you may need to use the official Microsoft Support and Recovery Assistant (SaRA) tool to completely uninstall and reinstall Microsoft 365.

How can I check if my Microsoft 365 subscription is still active?

You can verify your subscription status by visiting https://account.microsoft.com/services and signing in with the Microsoft account you used to purchase the software.
