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

Windows 10 product keys and activation - and the KMS angle

- That rather leads me towards the alternative suggestion made by : that instead of persisting with a clean install that seems not to be possible, I could try a different way of (re) activating the existing Win 10 by using the different key suggested. I hesitate to ask for an explanation of what that key is and why it might work. But right now I'm not sure there are any other possible ways forward.

Changing the product key to the generic Windows 10 product key will reset activation to the standard retail channel for activation. It might just activate (if there was a previous digital license for Windows 10 for that computer established with Microsoft). Once Windows 10 is back on the retail activation channel, then more than likely changing the product key to the Windows 8 product key using the same method may work.

Windows 8.1 pro + WMC key activation

I was considering buying a WMC pro add on for my windows 8.1 pro install, but have googled and found some people had trouble activating it. Has anyone on here got any experience with this.

As to my install, I have a real Windows 8 pro key. So I installed windows 8 pro using a MSDN retail .iso which was activated soon as it finished installing , then I updated to .1 pro.

When you buy the WMC add on, it changes your key, I have read some people have had trouble activating it, now mine activates from windows, I hate doing the phone activation crap, so I don't want to have to do that after the WMC add on finishes installing.

The question is, what happens to my windows 8 pro key, is it still usable? and how would i go about if I had to reinstall? would it have to be-

Install win 8 pro-update to 8.1-install WMC add on, or could i use a windows 8.1 pro with WMC disc?

Thanks guys

This worked for me last time with a Win 8 key.

Install Windows 8.1 and enter KMS key during setup. Once in windows change product key to my Windows 8 key. Go to add features and enter my WMC add-on key. Drink a beer to a job well done.
