Wife's at least 10 or 12 year old laptop with Windows 10 Pro died. The diagnostics in ROM, I guess, showed a bad hard drive. Put a new one in that passes the test.

Now I have no OS. I tried to download from Microsoft to make a bootable USB drive. The computer that I'm using is Windows 7. Unsuccessful, I think because I have no Windows 10 Activation Key.

How do I buy a Windows 10 activation key from Microsoft Store? I'm thinking of buying a bootable usb stick, too. Any recommendations?
