Windows 10: Windows activation error

Good day


I have an old PC That was not used for a long time, it had Windows 7 installed and the key is on a sticker on the box

This PC used a administrator login, not linked to any Microsoft account.

Recently the hard drive crashed and I was unable to recover any info.

I got a new hard drive and had to install Windows 10 because I could not get hold of a Windows 7 disk.


Now I am unable to activate Windows. with the following error:


We can't activate Windows on this device because the previous version of Windows was not activated prior to upgrading to Windows 10. Go to the store to buy a genuine Windows. Error code: 0x803F7001


Do I need to get hold of a Windows 7 disk and re-install before trying to upgrade to Windows 10?

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
