How to Activate Windows 8 RTM Enterprise Edition

If you installed Windows 8 RTM Professional, you were prompted for a license key before it would even get started with the installation, but if you installed Windows 8 RTM Enterprise Edition, it didn’t even prompt for a license key during the installation process.

Right click on “Command Prompt” and then click “Run as administrator”:


Run the following command, replacing the X’s with a valid Multiple Activation Key (MAK):

slmgr /ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

Refresh the Activation page and it will now show activated (with Internet access):

On Windows 8 Enterprise Edition (RTM), from a “Command Prompt” that was run as an admin, the following command prompts for a license key using a GUI interface:
