Software Licensing API
The Software Licensing API (SLAPI) can be used to determine a genuine Microsoft Windows installation, install and log an asset management license, and retrieve information about the licensing policy of a software component.
SLAPI is intended for use by developers of applications based on the Microsoft Windows Server 2008 and Windows Vista operating systems. Developers should be familiar with Windows-based programming.
For information about run-time requirements for a particular programming element, see the Requirements section of the reference page for that element.
