Windows – Changing the Unlock Code and Activating

Posted on by

KB ID 0000667 

Problem

Some versions of Windows 8 (Windows 8 Pro for example) ask for the unlock code as soon as you install them, I installed Windows 8 Enterprise on my PC at home today, and I couldn’t even change my user photo, because Windows hadn’t activated. When I tried, this is what happened.

Solution

As I had not yet installed a Windows unlock code, it’s safe to assume it had it’s in built KMS code, so I would need to change it to my own Windows code.

1. Press Windows Key+X to bring up the Advanced Context Menu >Select ‘Command Prompt (Admin)’.

2. Run the following command (where 12345-ABCDE-12345-ABCDE-12345 is YOUR Windows code);

[box]slmgr.vbs -ipk 12345-ABCDE-12345-ABCDE-12345[/box]

3. Then to activate your copy of Windows run the following command;

[box]slmgr.vbs -ato[/box]

Send and email to kmsadd@microsoft.com

Give them the following information.

  1. Company name.
