When you turn it on for the first time, you should be asked to set up windows. simple, self explanatory process. you don't need to know your key, it's already saved on a chip on your motherboard. if it asks, say you already have a key. I recommend you do the first set up without connecting your system to the internet (either with cable or wifi). when it asks for you to connect, say you don't have internet and you want to continue with the limited setup. Decline when it asks you about the digital assistant and turn everything off in the privacy settings. It will then restart and finally take you to windows. Then you can plug the cable or connect to wifi and continue with the following;
make sure you run windows updates and are up to date, might take a while
bottom left corner, where you see a search box, click and type check for updates, you will see it in the list, click and run updates, let it do its thing, it will restart the pc a few times, don't worry about it. keep going to check for updates until it says you are up to date.
you then need to go to HP's website and look for the BIOS driver for your model
