⊞ Upgrading Windows 11 Home to Windows 11 Pro Using the KMS Client Key

📋 Overview

This article walks you through upgrading a Windows 11 Home edition machine to Windows 11 Pro by installing the built-in KMS client setup key and activating against your organization’s KMS host. This approach is ideal for volume-licensed environments where you manage activation centrally.

🔑 Prerequisites

Before you begin, ensure you have:

1. Administrative privileges on the target PC.

2. Network connectivity to your organization’s KMS host (default TCP port 1688).

3. The appropriate KMS client setup key for Windows 11 Pro:

   NRG8B-VKK3Q-CXVCJ-9G2XF-6Q84J

4. (Optional) The fully qualified domain name (FQDN) or IP of your KMS server, if it isn’t published via DNS.

🛠️ Step-by-Step Upgrade
