### Can I use the same product key on multiple computers?

Most retail versions of Office allow installation on one desktop and one portable device. Office 365 subscriptions typically permit installation on up to 5 devices simultaneously.

### What happens if I lose my product key?

If you purchased Office digitally, you can often retrieve your key from your Microsoft account. For retail purchases without registration, recovery may not be possible.

### Do product keys expire?

Retail product keys don’t expire, but they may have activation limits. Subscription-based keys (like Office 365) remain valid as long as your subscription is active.
