📎 AI Summary:
The thread discusses how to reinstall Windows 10 on a Toshiba Satellite laptop after replacing the HDD with an SSD, with the original upgrade being free from Windows 8.1. The original poster does not have a product key, and responses suggest that Windows 10 may activate automatically if the system had a digital license or is linked to a Microsoft account. The conversation ends with the original poster mentioning using a MacBook to prepare installation media and a comment about Windows restore points, though no detailed solution is provided for restoring the system.

I have a Toshiba Satellite laptop, C55-A5172. Had win 8.1 but electronically updated to win 10. the hdd died so I replaced it with a ssd 2TB ranxiana model S101.
I have physically installed the new drive into the laptop. I do not know how to recover my win 10 to load back on to the drive. Since win 10 was an free upgrade from win 8.1 electronic download I don't have a activation key. Help getting my laptop up and running again would be much appreciated.
Thank you in advance for the help.

If you have the Windows 8.x key, install Windows 10 and enter that key it should activate. If the system has an embedded license in the firmware then you can just install Windows 10, skip the install activation and it should just activate.

If you sign into the compute with an MSA ( email ) and not a local account it may be tied to that account, so it should activate.

I am using a MacBook Pro to download the loader info, it takes about 5-10 minutes for the thumb drive

Windows restore points should be! My friend restored the system after a serious accident, but I don’t even know how to do it)))))
