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.
