Hello Chaitanya Jondhale,
These forums are for the support of Windows Genuine Advantage Validation issues. Your post does not appear to a be Vista Activation or Validation related and, as such, is off-topic (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
