Windows 10: Unable to activate windows on a second hand laptop

I recently purchased a second hand laptop off of eBay and I am unable to activate windows. I keep getting the message that it is unable to connect to "your organizations network" even after I have signed in with my personal account, I have not linked an organization nor do I have one to link. I do not know my product key and I have no system administrator to contact. I am getting the error code: 0x8007232B. The device came with Windows 10 but I believe it may have an un-official version.

Product Key Activation for second hand laptop?

I got a notification on my acer laptop (touchscreen) saying the windows 10 enterprise licence will expire soon and that I need a product key or something. I tried looking for ways to find the product key, but this is a second- hand laptop, I didn't receive the packaging or anything with it, so I'm not sure what to do ;-; I can't ask the person who gave it to me either. Is there a different way to activate it?

Windows won't install on second-hand laptop?

Also tried, indeed I had made the DVDs for windows that way. On my regular work PC, the DVDs work properly but as soon as I try them in my laptop... well. Then it goes hopelessly wrong. You know, I'll just keep this laptop on Linux Mint. Are we rid of the hassle with the windows DVDs, right? And at least it runs well. Although, the battery life could be a bit longer too. Only lasts an hour. Oh well, what do you want with a second-hand laptop, right? Am already happy THAT it picks up an OS. Strange, nonetheless.
