## Frequently Asked Questions

### Can I use one license key on multiple computers?

This depends on your license type. Retail licenses typically allow installation on one desktop and one portable device, while volume licenses may permit more installations.

### What’s the difference between a product key and a license?

The product key is the code used to activate the software, while the license is the legal agreement governing how you can use the software.

### Do I need a new key for Office updates?

No, your existing license key remains valid for updates within the same version. Major version upgrades typically require a new license.
