Asumption for this tutorial: You already have the right wildpacket driver for your card
There's 2 possible scenarios:
You did not already install the driver
You already have the card's standard drivers installed
In these examples, I'll use an Atheros card.
Driver not already installed
Plug the card in your computer, Windows will tell you it found new hardware and open the following:
Select “No, not this time” then click on “Next”.
Select “Install from a specific location (Advanced)” because we have a special driver and we don't want windows to use an existing driver (If windows find a driver that matches your card, it will use it, even if it's not the one you want) then click on “Next”.
Uncheck “Search removable media” and check “Include this location in the search” and browse for the directory where the driver is located (or enter the directory name if you know its name) then click on “Next”. Windows is now installing the driver …
… but since this special driver is not signed, it will give you a warning. You can safely click on “Continue Anyway”.
Wait a short while for windows to install the driver then click on “Finish” on the next screen.
Your card is successfully installed, you can now use airodump-ng.
Remarks
Only one card at a time could be used to capture packets (using multiple cards doesn't work).
