How to Activate Windows 10 with CMD: A Step-by-Step Guide

posted on October 13, 2025

Activating Windows 10 with CMD is a straightforward process that involves using the Command Prompt to enter a specific command that will activate your system. This method can be handy if you’re having trouble with the standard activation process. By following a few simple steps, you can quickly get your Windows 10 up and running.

Step-by-Step Tutorial on Activating Windows 10 with CMD

Activating Windows 10 using CMD involves opening Command Prompt with administrative privileges and entering a specific command sequence that will activate your copy of Windows. Here’s how to do it:

Step 1: Open Command Prompt as Administrator

To begin, you need to open the Command Prompt with administrative rights.

You can do this by typing "cmd" in the search bar, right-clicking on "Command Prompt," and selecting "Run as administrator." This step is crucial because you need administrator privileges to execute the necessary commands.

Step 2: Enter the Activation Command

Once the Command Prompt is open, type the command: slmgr /ipk your-license-key.

Replace "your-license-key" with your actual Windows 10 product key. This command will install your product key into the system.

Step 3: Activate Windows

After entering the product key, type the command: slmgr /ato.

This command tells Windows to attempt activation using the product key you just entered. It might take a few moments, but you should see a message indicating success if everything is correct.

Step 4: Verify Activation

Finally, you want to ensure that Windows is activated. Type slmgr /xpr into the Command Prompt.

This command will show you a message confirming whether your Windows is activated permanently or not. It’s a simple check to ensure everything went smoothly.

Now that you’ve completed these steps, Windows 10 should be fully activated. You can enjoy all the features without any of those pesky activation reminders.

Tips for Activating Windows 10 with CMD

  • Always run Command Prompt as an administrator to avoid permission issues.
  • Double-check your product key before entering it to prevent errors.
  • Ensure your computer is connected to the internet during activation.
  • Keep your Windows 10 product key in a safe place for future use.
  • If activation fails, verify the key is valid and hasn’t been used on another device.
