# Windows License Activation Guide
## Introduction to Windows Licensing
Windows operating systems require a valid license for legal use. Microsoft offers various licensing options depending on your needs, whether for personal, educational, or business purposes. Understanding these options is crucial before proceeding with activation.
## Types of Windows Licenses
Microsoft provides several licensing models for Windows:
### 1. Retail License (FPP)
Retail licenses are purchased individually and can be transferred between computers. They’re ideal for personal users who might upgrade their hardware periodically.
### 2. OEM License
Original Equipment Manufacturer licenses come pre-installed on new computers and are tied to the specific hardware they were originally installed on.
### 3. Volume License
Designed for businesses and organizations, volume licensing allows multiple installations under a single agreement.

– Compatible hardware meeting Windows system requirements
## Step-by-Step Activation Process

## Managing Your Windows License
### Transferring a License
Retail licenses can be transferred to new hardware:

2. Install Windows on the new device
3. Activate using the same product key

Run the command “slmgr /xpr” in Command Prompt (Admin) to view your activation expiration date.
## Enterprise Licensing Considerations
For businesses using volume licensing:
– Keep track of your Microsoft Agreement Number
