Sorry, but first of all, if you have having problems with an MSN password, we can't help with that as it is entirely administered by Microsoft.
Second, I wish we could help you, but sorry, due to changes in Community policy, we are no longer able to provide any assistance with password reset or recovery issues.
In addition, according to the Community's Rules of Participation:
4d. No posts shall include instructions or directions intended to bypass or subvert security measures, including passwords, locking mechanisms, fingerprint scans, etc., or to bypass any safety measures.
For assistance NOW, you have to contact your regional HP Customer Support location directly as they will confirm ownership of the PC before providing any assistance -- something we are not able to do from here.
