    I bought a new laptop with Windows 7 Pro on it and it was upgradable to Windows 10. However, the upgrade failed. Also my new laptop had a HDD so I replaced it with my old SSD. I installed Windows 10 from USB doing a clean install. However, it doesn't activate. I entered a Windows 7 Home Premium Key that I had from my previous laptop but that doesn't get activated and I get a 0xC004F050 error. How can I obtain the Windows 7 Pro key necessary to activate from the old HDD lying outside of any computer? Do I have to put it back into my laptop?
