Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi,
I understand how frustrating this can be after resetting your computer. Don’t worry, you usually don’t need a certificate to regain access to your Microsoft 365 apps.
You can reinstall office by following the steps below:
Go to https://account.microsoft.com/services
Sign in using the Microsoft account associated with your license.
Locate Microsoft Office and click Install.
This will download the Office installer.
Run the installer and follow the on-screen instructions.
After installation, open any Microsoft 365 app like Word or Excel.
Click Sign in and enter your Microsoft account used for the subscription.
Once signed in, the apps should automatically activate.
