Thank you again for your insight and rapid response.
I was not able to recover the Key via the
Neemobeer's tutorial , but I did find a link which seemed to provide a means of recovering the Product Key.
I ended up creating a .vbs File as instructed per the bottom of the attached link, and it seemed to be successful in retrieving my Product Key.
If you’re looking for your Windows 10 product key, you can find it by entering a quick command in the Command Prompt. Here’s how—plus a neat little trick for finding the product key using a Windows Registry method.
I am currently downloading Windows 10 Install on a USB in case I take this route.
Based on your input, etc, I am now leaning to getting a new HD and using the USB approach to download Windows 10.
As far as MS Office, I did not see any info on my Microsoft Account on office 2007, (currently installed on my T500), but I do see my subscription for Office 2016 which I had purchased with my T560.
Assuming that I change the HD in the T500, and reload Windows 10 via USB, will I be able to download Office 2016, (originally purchased for my T560), into my T500?
If so, that would be a good solution.
Thanks again for your valued input & help.
