Members

The SoftwareLicensingService class has these types of members:

Methods

The SoftwareLicensingService class has these methods.

Method Description
AcquireGenuineTicket Acquires a genuine ticket online.
ClearKeyManagementServiceListeningPort Clears any previously specified listening port. Applies to KMS hosts only.
ClearKeyManagementServiceMachine Clears the key management service machine name.
ClearKeyManagementServicePort Clears any previously specified port number.
ClearProductKeyFromRegistry Clears a product key from the registry.
DisableKeyManagementServiceActivation Disables volume activation through a KMS machine.
DisableKeyManagementServiceDnsPublishing Disables the DNS publishing on a KMS host computer.
DisableKeyManagementServiceHostCaching Disables the caching of the KMS hostname and port on a volume activation client.
EnableKeyManagementServiceLowPriority Enables the KMS service to run with low priority.
InstallLicense Installs a license for the current product.
InstallLicensePackage Installs a license package for the current product.
InstallProductKey Installs a product key.
ReArmWindows Resets the licensing status of the machine.
RefreshLicenseStatus Updates the licensing status of the machine so that applications have access to current licensing information.
SetKeyManagementServiceListeningPort Sets the TCP port on which a KMS host listens for activation requests. Applies to KMS hosts only. If a port is not specified, port 1688 is used.
SetKeyManagementServiceMachine Sets the name of the key management service (KMS) machine to use for volume activation.
SetKeyManagementServicePort Sets the TCP port that is used by a client to make requests of a KMS host. If a port is not specified, port 1688 is used.
SetVLActivationInterval Sets the activation frequency, in minutes, of how often the current machine should contact the key management service machine before the client is licensed. The frequency must be greater than or equal to 15 and less than or equal to 43200. An error is returned if the method is called and the machine is not a key management service.
SetVLRenewalInterval Sets the renewal frequency, in minutes, of how often the current machine should contact the key management service machine after the client is licensed. The frequency must be greater than or equal to 15 and less than or equal to 43200. An error is returned if the method is called and the machine is not a key management service.

Properties

The SoftwareLicensingService class has these properties.
