So, a while back I did a "fresh-upgrade" install of Windows 10 Pofessional.
That is to say that, in the days when Microsoft was still offering free upgrades to Windows 10 for qualifying licenses, I booted from a Windows 10 install disc and installed Windows 10 Pro directly to a blank, formatted hard drive, USING A WINDOWS 8.1 KEY (or Windows 7).
Is that original key that I used written anywhere to the fresh-upgrade install?
I've tried using both NirSoft ProduKey and Superfly-Inc's ShowKeyPlus to recover the Windows 8.1 / 7 Key, but it only shows me a Windows 10 Key (which is not the correct key I'm looking for).
Be that as it may, I'm still trying to determine the original key of the computer. – Daniel – 2017-03-12T09:54:20.217
what do you want to do? the original key is used to upgrade, legally you can't use the old key again. – magicandre1981 – 2017-03-12T17:54:38.383
