Not trying to do anything malicious or violate copyrights. Just out of pure curiosity.

If dd creates a full clone of a disk, will it work if I use dd to make a full copy of windows 10 with a license key to another drive and boot it on another computer and have it still worked?

    Does this answer your question? [Can you help me with my software licensing issue?](https://serverfault.com/questions/215405/can-you-help-me-with-my-software-licensing-issue) – Michael Hampton Feb 24 '21 at 20:57

    Win10 identifies your machine by its bios (efi) id + disk controller id. If you somehow can solve that these remain, for example by fine-tuned virtualization settings, problem solved. – peterh Feb 24 '21 at 21:06

Normally it would detect a hardware change, and you'd need to activate it again. That's a typical disaster recovery scenario, where your old computer was destroyed and you need to recover from backup.

Windows 10 encourages you to link a Microsoft Account to your computer. I'm not sure what complications would occur if two installations were signed in from the same product key.

  • But let's say it's something like ubuntu, dd should work fine as a full backup right? – Aviv Lo Feb 24 '21 at 21:28

    That's right. I'm saying it will work for Windows 10 also, re-activation is pretty normal thing to do and you shouldn't have license issues. I have a few PCs that did the Windows 7 -> Windows 10 free upgrade, in that case a Microsoft Account might be necessary to migrate hardware. – axus Feb 24 '21 at 22:09
