## Frequently Asked Questions

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

This depends on your Office license type. Most retail versions allow installation on one PC and one tablet, while volume licenses may permit more installations.

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

If you purchased digitally, check your Microsoft account or email receipt. For retail purchases without proof of purchase, you may need to buy a new license.

### How long does a product key remain valid?

Product keys don’t expire, but they may have activation limits based on Microsoft’s terms of service for your specific product version.

### Can I upgrade Office with my existing product key?

Upgrade eligibility depends on your current version and the new version you’re installing. Check Microsoft’s upgrade policies for specific details.
