# Microsoft Office Product Key: Essential for Activation and Full Features
## What is a Microsoft Office Product Key?
A Microsoft Office product key is a 25-character code used to activate your Office software. This alphanumeric sequence serves as proof of purchase and unlocks the full functionality of your Office applications.

– Activation: It verifies your copy of Office as genuine
– Full feature access: Unlocks all premium functions
– Security: Helps prevent software piracy
– Updates: Enables access to the latest security patches and features
## Where to Find Your Product Key
Depending on how you purchased Office, your product key may be located in different places:
– Retail purchase: On a card inside the product box
– Digital purchase: In your email receipt or Microsoft account
– Pre-installed on a new device: In the device documentation or BIOS
## How to Enter Your Product Key
To activate Office using your product key:
– Open any Office application (Word, Excel, etc.)
– Click on “File” then “Account”
– Select “Change Product Key”
– Enter your 25-character key
– Follow the on-screen instructions to complete activation
## Troubleshooting Common Issues
If you encounter problems with your product key:
