Solution 1

Scan HKEY_LOCAL_MACHINE SECURITY\SAM\Domains\Account registry key.
Use Win32::LookupAccountName to get User SID's and finally use Win32::Security::SID to get in string format.

Note that the SECURITY Hive is locked.

C++

DWORD SIDLength = 0;
	DWORD RefDomainNameLength = 0;
	SID_NAME_USE SIDNameUse;
	::LookupAccountName(NULL, _T("MYCOMPUTERNAME\\"), NULL, &SIDLength, NULL, &RefDomainNameLength, &SIDNameUse);
	PSID psid = (PSID)new BYTE[SIDLength];
	LPTSTR domain = new TCHAR[RefDomainNameLength];
	::LookupAccountName(NULL, _T("MYCOMPUTERNAME\\"), psid, &SIDLength, domain, &RefDomainNameLength, &SIDNameUse);
 
	//... use the SID (psid) here ...
 
	// ** Test **
	LPTSTR StringSid;
	::ConvertSidToStringSid(psid, &StringSid);
	::LocalFree(StringSid);
	// ** End Test **
 
	delete[] domain;
	delete[] (BYTE*)psid;
