Hi xiaoben,
These forums are for the support of Windows Genuine Advantage Validation or Activation issues. Your post does not appear to be Vista Activation or Validation related and is, unfortunately, off-topic for this forum (as well as outside my area of knowledge.
I suggest reposting your question to one of the Vista Newsgroups at http://go.microsoft.com/fwlink/?linkid=42486 or go to http://support.microsoft.com for additional support options.
Sorry I couldn't be more help,
Darin MS
