1. Single PC License: Each key binds to one computer.
2. Account Binding: Activation links your license to your Microsoft account for easy recovery.
3. No Updates for New Versions: Office 2019 gets security updates but no new feature updates; Office 2021 or Microsoft 365 is required for future features.
4. Volume Licensing: Available for businesses with multiple PCs; activation can be done via KMS or MAK keys.
5. Genuine Activation: Only genuine keys ensure updates, security patches, and compliance with Microsoft policies.
