As in my previous question, I'm working on reverting my ASUS 10TP system back to 8.1 so I can reinstall.
I installed 10TP near the beginning of the release cycles, this month I discovered that I couldn't just continue from 10TP to the full version of 10 (see other question). According to Microsoft, I need to downgrade to 8.1 using the media creation tool on another computer and reupgrade to 10 following one of the "correct paths."
Because I thought that getting 10TP on an OEM Windows PC was equivalent to the prereleases of say, Linux (silly me) and would eventually update, I didn't write down my product key or OS variant prior to running the media creation tool and getting 10TP. It happily installed and has been running well until I got the scary "I'm committing suicide" messages on Oct 1.
I have downloaded the Windows 8.1 Media Creation Tool on another PC per Microsoft's instructions. I used Nirsoft's Produkey to read the
Windows (BIOS OEM key), downloaded Windows 8.1 US English 64-bit, burned to DVD, and booted from it.
When I got to the "enter a product key" I got an error:
The product key entered does not match any of the Windows images available for installation. Enter a different product key.
So I downloaded and burned Windows 8.1 Pro (Since I have 10TP Pro), same error.
I still have the box the computer came in. It says:
OS TYPE:WIN8.1 64BIT-WITH BING
Just for fun, I used Produkey to grab the Bios OEM Key from my personal laptop. Plugging in that number into the Windows8.1 disc worked (no error). Of course, I've already got a computer with this key so I don't imagine it will work if I actually installed.
I'm going to try the steps detailed over on Clean install Windows 8.1 or Windows 8 from OEM key, but is there a way to tell what (Windows) OS was on the computer to begin with?
For future reference the Windows 8.1 Editions given in the media creation tool are:
Windows 8.1 N
Windows 8.1 Pro
Windows 8.1 Pro N
Windows 8.1 Single Language
Each with a 32 or 64 bit option.
