Windows 10: Error code 0x800705B4 of Windows activation issue

So I picked up a used but very nice gaming PC off a friend. He was honest with me about it not being a legitimate copy of windows and it has the activation error message in the lower corner.I went ahead and set it up and immediately bought a legitimate copy digitally. I used the "Change product key" and it takes awhile and then displays the 0x800705B4 error. So to summarize - non-legitimate windows 10 pro copy machine with a freshly bought windows 10 pro license leading to the error.I found people asking for this in other threads in my searches so I ran it if it helps.

Windows 10 will not activate Error code 0x803F7001

Possibly there can be the problem with Microsoft activation Server, so your Windows 10 is not activated. In this scenario, you need to wait and verify if it is the issue from Microsoft’s side. But if you are getting error code 0x803f7001, you can also try these steps:

1. Open Settings app. Then go to Update and security > Activation screen > Change product.
2. Type your Windows edition product key and click Next.
3. You’ll get We couldn’t activate Windows error message.
4. Retry steps 1-3 then type your 25-characters unique product key.
5. Wait for the process to complete, Windows 10 is activated.

Hope something helps this problem
