I have this problem 0x803fa067 on win 10 Pro and I'm really angry I don't know what to do about it and I don't understand why it's not working. I bought a new pc so will I have to buy new windows too? I wanted to use the Windows key from my old PC

I got a key from a yard sale and i entered it and gave me this error

If you clicked this video because your tranfer of keys didnt work, move on theres no solution here...

Hey i got the same error but when i clicked troubleshoot it said "Your copy of Windows cannot be activated. Check your network connection and try again. If your network connection works and this problem persists, please contact your system administrator."
I am using the same account as the one i used to download Windows and product key. The key version and the Windows version are the same. Might it be because i bought it from some sketchy website?
