Windows 10: Windows 10 Activation error after complete format HDD

Few year ago I had purchased a new laptop having Windows10 Home installed in it. Used it for a year after that it stopped responding due to too many errors then 2,3 times I did complete format at the interval of 3,4 months but now I am not able to activate my windows. Tried Microsoft log-in and Activation > Troubleshooting option. Nothing worked.

Windows 10 formatting ?

We upgraded windows 7 to 10. Many crashes and errors after that. So a format and clean install of windows 10. Activated automatically. Zero issues and no more crashes etc etc.
So I'm inclined to say to just go for it. And if a problem, then use your windows 7 key.

 

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:

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

Hope something helps this problem
