# Microsoft Office License Key: Essential for Activation and Full Features
## What is a Microsoft Office License Key?
A Microsoft Office license key is a unique alphanumeric code that serves as proof of purchase and grants you the legal right to use Microsoft Office software. This key is required to activate your copy of Office and unlock all its premium features.

Designed for businesses needing multiple installations. Offers centralized management tools.
### 3. OEM License
Comes pre-installed on new computers and is tied to that specific hardware.
### 4. Subscription License
Part of Microsoft 365 plans, requiring annual renewal but including continuous updates.
