# Microsoft Office License Key Activation Guide

## Introduction to Office License Keys

Microsoft Office license keys are essential for activating your software and unlocking all its features. Whether you’ve purchased a standalone version or subscribed to Microsoft 365, proper activation ensures you can use Word, Excel, PowerPoint, and other applications without limitations.

## Types of Microsoft Office Licenses

### Retail License

Retail licenses are purchased individually and can be transferred between computers, though only one installation can be active at a time.

Organizations typically use volume licensing for multiple installations across their network with centralized management.

### OEM License

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

## How to Find Your Office License Key

Your product key location depends on how you purchased Office:

• For retail purchases: Check the product packaging or confirmation email
