As you said I too face extremely irresponsive Taskbar particularly the Wi-Fi Network selecting sidebar that doent even popup when USB Tether is done. A sec I disconnect everything happens one by one immediately. I can't even diagnosis the IP of connection due to this lag despite its extreme slow..
I activated Windows 8.1 with a valid licence.
PC is only slow when tethering is ENABLED, not if i just
connect phone to computer.
I managed to get it working that way:
Pull out Lan-cable, but keep activated the Lan
Network adapter. Activate Tethering.
It just works fluid, dont know why.
