Question

Is it possible to check whether a Windows installation is Genuine or not programmatically?
Lets just say I want to check Windows 7 from C, C++, Java or Python.

Answer 1

this from CodeProject, in C++ ( Check for Windows Genuine in VC++ )

#include <slpublic.h>
#pragma comment(lib,"Slwga.lib")

bool IsWindowsGenuine()
{
    GUID uid;
    RPC_WSTR rpc=(RPC_WSTR)_T("55c92734-d682-4d71-983e-d6ec3f16059f");
    UuidFromString(rpc,&uid);
    SL_GENUINE_STATE state;
    SLIsGenuineLocal(&uid,&state,NULL);
    return state == SL_GENUINE_STATE::SL_GEN_STATE_IS_GENUINE;
}
