### 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 happens if I lose my license key?

If you purchased Office directly from Microsoft, you can often retrieve your key through your Microsoft account. For retail purchases, contact the seller or Microsoft support with proof of purchase.

### How long does an Office license key last?

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