# Windows License Activation Guide

## Introduction to Windows License

A Windows license is a legal agreement between you and Microsoft that grants you the right to use the Windows operating system. Whether you’re using Windows 10, Windows 11, or an earlier version, proper activation is essential for accessing all features and receiving regular updates.

## Types of Windows Licenses

### 1. Retail License

Retail licenses are purchased directly from Microsoft or authorized retailers. These licenses are transferable between computers (though not simultaneously) and typically come with both 32-bit and 64-bit versions.

### 2. OEM License

Original Equipment Manufacturer (OEM) licenses come pre-installed on new computers. These are tied to the specific hardware they were originally installed on and are not transferable to other devices.

### 3. Volume License

Designed for businesses and organizations, volume licensing allows multiple installations across an enterprise. These are managed through special activation servers within the organization.

## How to Activate Your Windows License

### Method 1: Online Activation

This is the simplest and most common method:

1. Click the Start button and go to Settings > Update & Security > Activation
2. Click “Change product key” if you have a new license
3. Enter your 25-character product key
4. Click “Next” and follow the prompts
5. Windows will connect to Microsoft’s servers to validate your license

### Method 2: Phone Activation

If you don’t have internet access:

1. Follow steps 1-3 from online activation
2. When prompted that online activation failed, select “Activate by phone”
3. Call the number provided for your region
4. Provide the installation ID displayed on your screen
5. Enter the confirmation ID provided by the automated system

## Troubleshooting Activation Issues

### Common Problems and Solutions

#### 1. “Windows is not activated” Error

If Windows suddenly shows as not activated:

• Check your internet connection and try activating again
• Run the Activation Troubleshooter (Settings > Update & Security > Activation)
• Verify your product key is entered correctly

#### 2. “Product key already in use” Message

This typically occurs when:

• You’ve reinstalled Windows on the same hardware
• Someone else is using your key (if it’s a retail license)
