Ok, from the site you started with (http://www.microsoft.com/en-us/server-cloud/products.aspx) I clicked on Server Virtualization > Technology Solutions > Virtualization & Management > IT Pros Start Here > Downloads

Yeah, that's messed up.

It looks like the microsoft.com/* site has become more of an executive summary for certain products, and for anything remotely technical you should always start at technet or msdn. The clue seems to be the "IT Pros/Developers Start Here" links.
