## Frequently Asked Questions

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

This depends on your Office version. Retail versions typically allow installation on one PC and one Mac, while volume licenses may permit more installations. Always check your specific license terms.

### What if I lost my product key?

If you purchased digitally, check your email or Microsoft account. For physical purchases, contact Microsoft Support with proof of purchase.

### Does my product key expire?

Perpetual licenses (Office 2019, 2021) don’t expire, while Microsoft 365 requires renewal. Subscription keys remain valid as long as your subscription is active.
