Normally Windows 7 is very good at analyzing your hardware and driver updates via Windows Update. These are normally presented as optional updates that you need to manually select in order to install. If you can get your computer connected to the Internet via a cable, it should do the work for you.
Another possibility if you can get an Internet connection is to let HP do the driver-detection for you : Go on the English version of the page you linked-to. This brings-up a dialog with a "Check now" option for HP to check all your drivers for you. Click it.
Next click "Verify products now". This will get you to a page that will ask to install software in your browser. Follow the steps. (This is where I stopped, since I don't have an HP computer.)
If this doesn't work for you, go into the Device Manager and look at the Properties of the network device. The exact model should be there.
For really difficult cases, the page Best Free System Information Utility lists several utilities that could give as much detail about your hardware as required to find out what model of card you have.
And finally, normally an installation of a network driver should fail if a compatible device is not found, so you could just try all the 11 possibilities. But I don't have experience with HP driver installations.
