Generally, fixes are more likely to get committed when they don't break anything (did you run all the conformance tests?), their tests cases pass on all versions of windows (did you send your patch to testbot?), improve the behavior of a real program (I don't think you have demonstrated this yet), and are written from a position of relatively deep understanding.
So you might want to find a more solid fix for your first submission.
Welcome, and good luck! - Dan
