# Office License Key Activation Guide

## Introduction to Office License Keys

Microsoft Office is one of the most widely used productivity suites in the world, offering essential applications like Word, Excel, PowerPoint, and Outlook. To use these applications legally and access all features, you need a valid Office license key. This guide will walk you through everything you need to know about Office license keys and how to activate them properly.

## Understanding Office License Types

Before activating your Office license key, it’s important to understand the different types of licenses available:

### Retail License

A retail license is purchased individually and can be transferred between computers (though not used simultaneously). This is ideal for personal use or small businesses.

### Volume License

Designed for organizations, volume licenses allow installation on multiple computers under a single agreement. These are typically managed through the Volume Licensing Service Center.

### OEM License

Original Equipment Manufacturer licenses come pre-installed on new computers and are tied to that specific hardware.

### Subscription License

Office 365 (now Microsoft 365) uses a subscription model where you pay annually or monthly to access the software and receive regular updates.

## Where to Find Your Office License Key

Your Office license key might be located in one of these places:

– Email receipt if purchased digitally
– Product card inside the physical package
– Microsoft account if purchased online
– Sticker on your computer (for OEM versions)

– Volume Licensing Service Center (for business licenses)
