Enabling windows authentication in IIS

iisiis-7sitefinity

I am on vista home premium (32 bit) and I need to enable windows authentication for IIS because the Sitefinity sample site returns a 401. However, in add windows features, there is no sign of windows authentication despite having expanded all the treeviews.

How can I enable windows auth?

Thanks

Windows authentication is a feature that's only available in upper editions such as Business/Ultimate as Tchami pointed out.
