It seems there is no driver for Windows 10.

Hi Shadman

While the response above is correct (there is no Windows 10 driver) the TP-Link Windows 8.1 driver file works fine in the Windows 10 technical preview.

So that is driver: TL-WN722NC_V1_140918
From the following page: http://www.tp-link.com/en/support/download/?model=TL-WN722NC&version=V1#tbl_a

Download it with another computer and unzip it to a USB drive.

In Windows 10 I then plugged in the wifi (which doesn't work by default), went to device manager, found the wifi device and told it to manually install a driver and pointed it at the USB drive. Worked no problems.

Cheers
