I ran across an interesting tidbit today. I built a Windows 8 box to take to MMS. While I was installing all my normal software, I got a weird error message while testing the Cisco Anyconnect VPN client.
When I tried to connect, it would give and error that it was not able to activate the adapter. A quick Google search and I had the answer. It looks like the installer puts some bum data in the DisplayName registry value so you need to open that key up and remove the bad data.
Open the following key:
Change the DisplayName string to “Cisco AnyConnect VPN Virtual Miniport Adapter for Windows x64”
I only tried this on the x64 CTP build of Windows 8.
