3-4 Years later......
I found the code which is related to that GetThreadId error in kernel32.dll, using CFF Explorer i got to locate the API call, but however changing the name or function will still get me error
"Entry Point Not Found", which means unlike the Extended Kernel in Vista which you can edit the functions on the Firefox executable, but on XP, not at all! I am using Windows XP Anime Edition SP4 upgraded for this investigation on Chrome 50
