Is Window's OEM license restricted to original hard drive?

I bought a Windows 7 pro OEM license from a reputable place. Then I upgraded  to Windows 10. I know I can't move it to another machine. But can I upgrade to an SSD?

OEM licensing is all about the motherboard, pretty much anything else you can change.
Because it's single activation though, if you reinstall you may get asked to contact Microsoft to explain why it needs activating again but it's a legitimate reason.

Win 10 upgrade registration is a hardware fingerprint of the machine taken at the time of upgrade, this includes the HDD identity but there is a weighting system for changed hardware components that is allowable before you're prompted to get in touch.  HDD to SSD shouldn't be one of them.

Also - and this is a technicality.  Only your base Windows 7 install counts as OEM.  Because you used the free upgrade your Windows 10 install isn't an OEM install.

You can change the hard drive. In fact, once you have upgraded to Windows 10, the licensing is stored in the Microsoft Licensing Server and that permits you to change drives.
