ForTraffic Manager virtual machine instances (excluding software based variants running on Linux or UNIX instances), a license key might be prebuilt into the Traffic Manager machine image. You do not need to request a license key for new Traffic Managerinstances launched from these images. Equally, you cannot delete the built-in license key for these product variants.

For Traffic Manager software deployments and virtual machine images without built-in licenses, you apply a valid software license key during installation.
