The Official Microsoft Redemption Portal
To ensure your license is 100% authentic and linked permanently to your identity, Microsoft provides the centralized portal: setup.office.com (or account.microsoft.com/services).
Step-by-Step Activation Instructions
- Open your browser and navigate to https://setup.office.com.
- Sign in with your standard Microsoft Account (Hotmail, Outlook, Live, or your work email).
- Enter your 25-character product key:
XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
- Select your preferred Country/Region and Language.
- Click Next. The key is now permanently bound to your account.
- Click Download Installer and run the official setup file.
How to Reinstall in the Future?
If you buy a new computer or wipe your SSD, you never need to type the key again. Simply log into account.microsoft.com/services and click Install next to your registered Office 2024 license.
