Installing/Adding IIS Windows Authentication feature in Windows 8

While installing the BizTalk Adapter Service I got the error "IIS Windows Authentication feature must be installed". As I am investigating Windows Azure Service Bus from my workstation running Windows 8, I don't have the convenience of the Server Manager to turn in on. Instead you will find it under the Windows Features - search for "Features" under "Settings" (or with 8.1 you will get the aggregated results). Below are screenshots showing the tree under which you can find the feature.
