Mark,
I'm experiencing similar difficulties with the latest 82579V driver, dated 2/21/2013, version 12.6.45.0. These properties are listed for the network adapter properties. The version that was listed in the Programs and Features control panel is 18.x. I only see the generic Microsoft dialog boxes, not the Intel dialog boxes with all the additional options.
I have since reverted to 17.4.95.0 (viewed in Programs and Features control panel). The Intel options are all displayed normally.
I followed all the steps you advised telecore to do. Is there something else I can try?
I am running Windows 7 Ultimate x64.
Thanks!
