Hi, good day! I'm John Dev a Windows user like you and I'll be happy to assist you today. I know this has been difficult for you, Rest assured, I'm going to do my best to help you.
Since your copy of Windows is pre-installed on your computer and previously activated, it is an OEM license that is attached to the motherboard and is not transferable. I'm sorry, you need to get a new one.
Kindly let me know if this helps or if you have any further concerns by clicking the "Reply" button at the end of my response. I will appreciate it.
Kind regards,
John DeV
