Follow each step carefully for successful activation.

Step 1: Open Command Prompt

• Click on the Start menu.
• Type "Command Prompt" in the search bar.
• Right-click on Command Prompt and select Run as administrator to open it with administrative privileges.

Step 2: Enter Activation Commands

• In the Command Prompt window, type the following commands one by one, pressing Enter after each command:

  slmgr /ipk <your-product-key>
  

  Replace <your-product-key> with the activation key you want to use. If you don’t have one, you can use the generic keys provided by Microsoft for activation.

  slmgr /ato
  

• These commands will initiate the activation process. The first command installs the product key, and the second command activates Windows.

Step 3: Check Activation Status

• After executing the commands, check whether Windows is activated successfully. Type the following command:

  slmgr /xpr
  

• A window will pop up indicating the activation status of your Windows installation. If it says "The machine is permanently activated," you have successfully activated Windows.

Step 4: Remove the Watermark (if necessary)

• In case the "Activate Windows" watermark persists, you can try the following command in the Command Prompt:

  slmgr /rearm
  

• This command resets the licensing status and removes the watermark. Restart your computer for the changes to take effect.

Tips for Successful Activation

• Ensure you are running the Command Prompt as an administrator for the commands to work properly.
• If you encounter any errors, double-check the commands for accuracy.
• Keep your system updated to avoid compatibility issues with activation.
