Not sure where to place this question but hoping someone here can help me.

I bought a laptop from an airport auction. Items that are lost and not recovered for over a year get sent to auction to clear out the lost and found.
This laptop seemed like an okay laptop to use while on the go so I grabbed it from the auction.

I formatted the drives, reinstalled windows and had it up and working. I was doing some windows updates to get everything up to date from the fresh install and when it rebooted I get a message on the screen..

"If this laptop is found, please contact (INSERT COMPANY LAPTOP USED TO BELONG TO) IT help desk (XXX) xxx-xxxx.

Tried calling the company, they want the laptop back and said TSA would have to reimburse me. I dont want to deal with TSA or this company. Is there a way to completely wipe their controls off?
