Erased the windows server 2016 key. Where to go?

Question

Windows Server

We bought two servers for resale, Windows Server 2016 Standard was installed. I should have messed around with this server before reselling it. Windows was installed with the "installation" key and, accordingly, not activated. The "specially skilled" employee overdid it and erased three characters from the sticker. Can something be done about it? do not offer to take your hands off - the employee is the boss)))

Answer 1

Read the key from the system. Download ProduKey (In Zip file) .

Answer 2

Check with OEM supplier
