So I have been buying parts to build a new PC. And I was wondering if it was legal to migrate the pre-installed OS (Windows 10 Home) from my laptop to my brand new hard drive. I am aware of the risks and setbacks (Activation, whether or not it will even let me, etc.) but I simply want to know if it is legal for me to do this.
Most of the laptops I work on, HP business, have their Windows licenses "burned" onto the motherboard. So even if you switch hard drives, as long as you are installing the correct version of Windows it should have no problem authenticating. Cloning the hard drive also works fine. As for legal, I don't see why not seeing as you are not trying to remove it from the laptop and place it on another laptop.
