Hello, I run a small company and give my employees tablets for daily orders. I recently had to fire a worker and asked him to return his surface he did and we made sure it worked before he left. I sit in on the desk and left it alone for 2 months. Today i went to charge the surface in prep for a new employee and when it turned on user and password locked. I did the recovery steps from microsoft customer service. And was prompted for bit locker number code which i do note have. I called the previous employee he said kick rocks. so my options? trash its? try a recovery image ? my company dosent have an it guy, I pretty much try to google/ fix things on my own any help would be great.
