Hi,
After a windows 10 re-install on date 22.11.2025, I can`t activate my windows 10 and the serialkey-number will not show up in my invoice, it only shows that I have bought windows 10 home edtition and what it did cost. I do have a documentation on that I own a windows 10 home edtion, and its bought directly from Microsoft. Current Windows 10 home edition is used in EU/Scandinavia.
I have tried the normal trouble-shooter in the actvate menu, and got the check-box "cheched" and got errorcode: 0x803F700F. I also tried to activate pc unit from my account on the web, but no luck.
Also got lot of help from chatGPT and we tried "something" in the CMD, but still not resolved.
Hope someone can help me activate my windows home edition manually.
Best Regards Raymond H

If you bought from the windows Store then it is a digital licence and you need to use the activation troubleshooter.
Had you selected Changed hardware when you say you checked a box?
Did you buy the Windows 10 licence from the Microsoft website instead?

Hello,
I'm sure you have already tried several troubleshooting steps, but please refer to the Microsoft support article again for guidance on resolving activation issues.
Using the Windows Activation troubleshooter
If you have a Windows 10 product key, please enter it directly.
If you do not have one, please contact Microsoft Support for further assistance.
