If it's not showing an error in Drupal, then it's something in your PHP installation. On Windows you do have to set it for a SMTP server in php.ini. I would check that. If you're still having troubles, then I would look at using the SMTP module and a 3rd party STMP service (if not a lot of emails, then GMail can be used):

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?
