Identifying the HBA WWNs in a Windows system

Every once and a while I have to hunt down the WWN of an HBA. On Linux systems, there is normally a combination of LSPCI and searching in /proc that can get you the answer. But how to do it on Windows?

I found the page http://wintelguy.com/2010/20100117_find_wwn.html, that points to a MS Utility that quickly scans and outputs the WWN for all installed HBAs.
