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

Windows 10 activation failed with error: 0x803F7001

I tried to activate Windows 10.  It failed with error 0x803F7001 and a description stating that the "Previous version was not activated". Following are the steps I performed to get to where I am now:

1. I have a laptop which had a single HDD and an OEM copy of Windows 8.1 pre-installed on it. I had no other drives.
   
2. In July 2015, I took advantage of the free Windows 10 upgrade and successfully upgraded from Windows 8.1 to Windows 10. I did not perform a clean install, just a regular upgrade from 8.1 to 10 on my HDD. I had no activation issues – everything worked like a charm.
   
3. Yesterday I physically removed my HDD from my laptop and inserted my SSD.
   
4. I performed a clean install on the SSD using the Windows 10 media creation tool.
   

Windows 10 will not activate. I am getting Error: 0x803F7001 with a description stating that the "previous version of Windows on this machine was not activated" which is false as described in my steps above.

I understood that the Windows activation servers blueprint your machine, taking the key from the BIOS and using that as a method of activating Windows 10. I also understood that in order for this to happen, you have to first upgrade to Windows 10 normally from Windows 7 / 8 (not clean install) after which you can perform a clean install. I have done just that. Then I swapped out my HDD (with the activated Windows 10 on it) for an SSD to perform a clean install. What did I do wrong?  How can I resolve this?
