I recently got a PC refresh and my company just gifted me my old Dell Latitude 7480. I am trying to create a machine that I can use for personal purposes and removing everything about it related to my employer.

I have removed the BIOS password, updated to the latest BIOS that I got from Dell, and and wiped the hard drive. I created Windows installation media on USB with another computer.

I reset to BIOS defaults, booted from the USB, and got most of the way through the Windows installation process and had it say, "Welcome to \[MY COMPANY\]!" I don't understand how it can still have any record of being my old work computer as I've reset to BIOS defaults and wiped the hard drive.

What am I missing?

Any help is much appreciated!
