Why Microsoft decided to stop supporting one of its own products in its own OS is beyond me.  I guess they figure webcams are a disposable item.  I was able to get my VX-3000 working with these drivers.  This download includes 32 and 64 bit drivers for the VX-1000, VX-3000 and VX-6000 cameras.  I have only tested with the 64 bit VX-3000, so YMMV.
