Most windows machines don't have a SMTP Service to forward the email. I believe XAMPP, from apache friends includes a product call Mercury mail for this reason, although I haven't been successful in getting it running.
Good Luck.

Has the hosting server ever sent email? Are any other emails sent from site? Might not be related to Drupal.

Dear All, I am on windows and realized that no emails have been sent for instance when a new user is created. Did some googling but haven't found a definitive answer. Anyone had similar experience?
