Updating to KMS from an MAK Installation | IT@Cornell (2024)

Cornell's site license for Microsoft Windows and Microsoft Office Professional Plus provides unlimited licensing via our Key Management Service (KMS). This page provides instructions for technical support providers (TSPs) to switch a computer from the earlier Multiple Activation Key (MAK) system to the preferred KMS system.

Switching a machine from MAK to KMS requires use of the Windows command line. You will need to issue Visual Basic commands to replace the existing MAK product key with a Generic Volume License Key (GVLK). If your network is not set up for autodiscovery, you will also need to issue additional commands to tell the machine the URL of the KMS server, and to start the automated activation process.

KMS activation can be blocked by a firewall. Please be sure that any firewalls between the client machine and the KMS server are open to incoming and outgoing traffic on TCP port 1688.

This page is intended for technical support providers and network administrators. If you're not one of those, you should talk to your TSP or net admin before proceeding.

Covered Products

Cornell's KMS activation service will automatically activate the following Microsoft products if they had been installed from the Cornell site license version of the installers.

• Windows 7 (Enterprise or Professional)
• Windows 8 (Enterprise or Professional)
• Windows 10 (Education, Enterprise, Enterprise 2015 LTSB, or Professional)
• Windows Server (2008, 2008R2, and 2012)

Our KMS service will not activate versions of the above software that were installed from OEM or retail versions of the installers.

Switch Activation from MAK to KMS

Updating an installation of Windows of Office entails entering commands at a command prompt. The commands you enter depend on whether your local area network has been configured to allow KMS autodiscovery. Networks administered by CIT are already configured for KMS. More information about autodiscovery can be found on our main KMS page.

If you aren't sure whether your local area network has already been configured for KMS, you can use the KMS manual configuration instructions.
