So, before you can update the drivers for a specific piece of hardware, you have to extract the files from the download you completed in the previous step.
Windows 7 has built-in compression/decompression software but we prefer a dedicated program like the free 7-Zip, mainly because it supports so many more formats than Windows 7 does natively.
The first thing you need to do is to download the latest driver for the device from the hardware maker's website.
Updating drivers in Windows 7 should take less than 15 minutes for most kinds of hardware.
In this tutorial, we'll be updating the driver for the network card on computer running Windows 7 Ultimate.
So while you may know that a folder you've selected has all sorts of files in it, it's an INF file that the wizard is looking for.
Not sure which INF file to choose when there are several?
If so, there's no reason to continue with these steps - just run the program and follow any instructions.
