http://technet.microsoft.com/en-us/magazine/2009.07.cableguy.aspx titled
"Support for IPv6 in Windows Server 2008 R2 and Windows 7", with a
section labeled "The Argument against Disabling IPv6".

"From Microsoft's perspective, IPv6 is a mandatory part of the Windows
operating system [...] Therefore, Microsoft recommends that you leave
IPv6 enabled, even if you do not have an IPv6-enabled network, either
native or tunneled."

Disabling IPv6 *entirely* is impossible (lo will stay), but some partial
disabling can be done with http://support.microsoft.com/kb/929852 . But
it will come with pain to do so.

This case closed now? :)
