SharePoint 2007 Web Folders

I've been working with SharePoint 2007 for so long now on my office desktop and laptop, that it seems that I don't remember some of the SharePoint 2007 requirements. Working on a fresh virtual machine that has WSS 3.0 installed and running, I've tries to open a Pages Library as a Web Folder. The result was a nice error message telling me "Your client does not support opening this list with Windows Explorer." This seemed a bit strange, since I'm working on the SharePoint server itself, which is a fully updated Windows Server 2003 (all patch and updates installed), and I'm browsing using Internet Explorer 7 (again, fully updated). After googling a bit, it seems the resolution was hidden in a forum with a link on page 2 of Google. The topic forwarded me to the following Microsoft page: Software Update for Web Folders (KB907306) I'm not sure if I should say that this update should come as part of the Windows Update or not, but I'm sure glad I've found this!
