Use Windows API Directly

#ifdef _WIN32
#include <windows.h>
#include <securitybaseapi.h>
BOOL IsAdmin() 
    SID_IDENTIFIER_AUTHORITY NtAuthority = SECURITY_NT_AUTHORITY;
    PSID AdministratorsGroup; 
    BOOL result = AllocateAndInitializeSid(&NtAuthority, 2,
        SECURITY_BUILTIN_DOMAIN_RID,
        DOMAIN_ALIAS_RID_ADMINS,
        0,0,0,0,0,0,
        &AdministratorsGroup);
    if (result) 
        CheckTokenMembership(NULL, AdministratorsGroup, &result);
        FreeSid(AdministratorsGroup);
The Return Values:
