Go to Device Manager, uninstall the network card, reboot.

It will force Windows to re-install the card and reset any network configuration.

Do you see the card in Control Panel\Network and Internet\Network Connections ?

If so, can you configure it using the GUI (meaning right click on it and click on Properties)?

I configure it it appears as an unspecified device if I right click to update it just sits on installing software and does nothing

this has only happened since the windows updates which I have now removed
Dan CraciunIT ConsultantCommented:
OK, so you no longer have the driver installed. I assume in Device Manager it's either under Unknown devices or has an exclamation mark (meaning the driver cannot start).

You can try
- shut down the machine
- from Hyper-V manager, remove all network adapters attached to that VM
- start the VM, let it fully start, then shut it down again
- again, from Hyper-V manager, add a network adapter
- start the VM, check in Device Manager that the card was installed properly
- configure the IP/gateway/netmask, using whatever method you like.
