You need to uninstall the xennet driver - this should be doable from add/remove 
programs but I've never tried removing an individual driver before.

Once you do that, you need to undo the following that were set from the inf 

HKLM,"SYSTEM\CurrentControlSet\Services\XenPCI\Parameters", "hide_devices", 
0x00010008, "#vif#"
HKLM,"SYSTEM\CurrentControlSet\Services\XenPCI\Parameters", "hide_devices", 
0x00010008, "VEN_10EC&DEV_8139"
; tell Qemu to hide stuff
HKLM,"SYSTEM\CurrentControlSet\Services\XenPCI\Parameters", "qemu_hide_flags", 
0x00010008, 2

So go into HKLM\SYSTEM\CurrentControlSet\Services\XenPCI\Parameters and remove 
"#vif" and "VEN_10EC&DEV_8139" from the hide_devices key, and remove "2" from 
qemu_hide_flags. On the next boot, xenpci shouldn't hide the qemu network
