Activate Windows 10 Using CMD – Step-by-Step Guide (2025)

If you want to activate Windows 10 using CMD, you can do it in a few simple steps using a valid product key and the built-in Command Prompt tool. This method is often used when you don’t have access to a graphical interface or need a quick way to activate Windows without third-party tools.

Why Use CMD to Activate Windows 10?

The Command Prompt (CMD) is a powerful built-in Windows utility. When used correctly, it allows you to manually install a product key, connect to a KMS (Key Management Service) server, and activate Windows without going through the Settings interface.

This method is best for system administrators or users who prefer command-line operations.

Step-by-Step Guide to Activate Windows 10 Using CMD

Before you begin, make sure you have:

• A valid Windows 10 product key
  
• Administrator access to your system

Step 1: Open CMD as Administrator

• Press Win + S, type cmd
  
• Right-click Command Prompt > select Run as administrator.

You must run CMD with admin privileges to allow system-level changes.

Step 2: Install Your Windows 10 Product Key

Type the following command and hit Enter:

slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

Replace these XXXXX with your actual product key.

This command installs the new key into your system.

Step 3: Connect to the KMS Server (if needed)

If you’re using a KMS activation method, enter:

slmgr /skms kms.example.com

Replace kms.example.com with your actual KMS server address.

Skip this step if you are activating with a retail or MAK key.

Step 4: Activate Windows

Now enter the activation command:

slmgr /ato

This tells the system to attempt activation using the installed key
