The Windows SteadyState Application Programming Interface (API) consists of a Windows Management Instrumentation (WMI) interface that allows a member of the Administrators group to query whether Windows Disk Protection has been turned on. The name of the API is Sctui.exe and it is located in the following folder:
%systemdrive%/Program Files/Windows SteadyState.
If Windows Disk Protection is turned on, an administrator can also use this API to modify the specific disk protection level for changes made to the hard disk.
The WMI interface has five properties: EnableWDPAndReboot, CurrentStatus, CurrentMode, DisableWDPAndReboot, and PersistDateTime.
