With VMWare Workstation installed, I found VMware Network Adapter VMnet1 and VMware Network Adapter VMnet8 network adapters are also installed, but with these 2 adapters it just screwed my Live Messenger (both 2009 and 2011 versions, on both Vista and Win7) video call.
After I disabled these 2 adapters, restarted machine my video cal works again.
Any other solution?
