Hmm, on windows, eh? I could give you config on linux in no time, however I'm not sure where are all the config files stored on windows.
Basically you need to
- create a self signed certificate or buy a cert from some public CA
- install the certificate
- enable mod_ssl
- enable https virtual host
- restart apache
How about some config examples on windows? »
