Windows 10: Upgrade From 8.1

    Upgrade From 8.1


    As I understand it we can still Upgrade to Windows 10 from Windows 8.1. My question is, how?

    I have an old Windows 8.1 machine that I don't know the origin of, and if Windows 10 was ever installed or not. It's a recovered from death machine that still works but did not have a HDD in it when I got it. The Tower has been put through its paces and all it working well.

    1. Do I need to Mount the Windows 10 iso on Windows 8.1 and Click the Setup File, or can I just do a Clean Install of Windows 10 from a DVD or USB?
    The reason I ask is, I was trying to sysprep this machine with Windows 8.1, but that did not go well and was just to much work. So Windows 8 works, but from what I understand it is a little broken...for lack of a better term. Apparently running sysprep on Windows 8.1 breaks it, and I did not know the proper path to do so at the time. So forget sysprep, I just want to get Windows 10 on there.

    Thanks FM

    Was this machine built for Windows 8 and originally had 8/8.1 installed by the OEM? If so, then there should be an key embedded in the firmware. A clean install should find this key and use it to activate Windows 10. An OEM Windows 7 machine would have a marker in the firmware, but not a full key.

    If the installed Windows 8.1 is activated, then mounting the ISO and running Setup should upgrade to 10 and activate.

    Either way, once 10 is installed and activated a digital licence will have been stored on Microsoft's activation servers linked to the hardware ID of this machine. Once you have a digital licence you are free to do a clean install of the same edition (Home or Pro) and it will activate automatically from the digital licence.

    If you are uncertain of the origins of this PC and whether it has an embedded OEM key or marker, then ShowKeyPlus can tell you.

    Got it, I'll try the Clean Install, and use ShowkeyPlus before just to see.

    Yes, I'm sure it was OEM W-8 Install, it has the sticker on it, and if I remember correctly that is what it states at the Dell site. Right now don't know if it was 8 or 8.1, will get back to it tomorrow.

    Well, you should have said it was a Dell. Go to the Dell support site and enter your service tag and you'll get the full specifications for the PC. The System Configuration section shows the configuration as originally suppled, including the original OS.

    A note: the original Upgrade to Win10 has the specification of needing Win7 w/SP1 or Win8.1. Fortunately the more than a dozen I've done fit the bill, haven't had to try with Win7 no/SP or Win8.0. I do have 2 Dell computers, OptiPlex 755 and Inspiron 530S [SFF] that cannot get drivers for the onboard Intel Express video so I added in a Sapphire-brand ATI Radeon 2400 HD card on both and the IP/Insider Preview latest Version and Build works fine for a non-gamer.

    Windows 7 without SP1 and Windows 8.0 will upgrade just fine.

    Been there done that, that's why I said "I have an old Windows 8.1 machine" but I understand getting the deets correct. I was going by memory and just second guessed myself, should have looked again. Another reason why I kept the machine, it's quite modern in that aspect.

    That was a system requirement of the original 'Get Windows 10' app (GWX). A manual upgrade using an ISO has no such restrictions.

    Yep, that was the reason for the word "original" in my post. Things did change and seemingly for what I had to work with coincided with the expiration of the 1-year offer.
