Need to Change Administrator without PIN

[audrey1995]

I bought this laptop (HP Envy 13) last year when my boyfriend and I were together. I brought it home and went to work. When I came back he had set it all up with himself as the administrator. Since then, he has left and moved to a different state, I had deleted his phone number at that time and neither of us are on social media for me to ask him what to do. I do not know the PIN and I can't download anything. It's like I spent a ton of money on a laptop that isn't even mine. It's very frustrating because every kind of "reboot" or any changes that I need to make, I can't because I don't have the administrative rights or PIN. How can I wipe the laptop to be able to make this laptop my own without any login information on his part?

If your PC is a 2016 model or newer, you should see if you can make a bootable USB recovery drive using the HP cloud recovery tool on a working PC.

The recovery drive can then be used to install Win10 and the HP drivers and utilities that originally came with your PC.

While you could also take this laptop to a local laptop repair shop and they could get you access, the problem is that your boyfriend could have loaded it up with all kinds of stuff -- some of which it might not be able to detect.  Your best bet will be to start out with a "clean slate" using the media described above.
