    Win8.1 to Win10 and Win8.1 BIOS Product Keys on SP2?

    Hey all,

    I have been going crazy trying to find the nitty-gritty details of what goes on under the hood with the upgrade from Windows 8.1 to Windows 10 on a Surface Pro 2 I am considering upgrading.

    I am aware the many Windows 8.1 devices have OEM Product Keys embedded in the BIOS. I am trying to find information on how Windows 10, if installed from a .ISO bootable media, interacts with this key, and how Digital Entitlement plays into all of this. It's currently hard for me to make sense of a lot of this. Can anyone help clarify how all these elements play with one-another?

    Another question regarding this process I have currently: If I use a NEW Windows 10 product key during installation, would the new key replace the previous (8.1 OEM) one in the BIOS?

    The more I find out about all this, the more mystery there seems to be to it. I am just trying to find the cleanest way to install Windows 10 on a Surface Pro 2, and this BIOS OEM key and Digital Entitlement vs. Product Key thing is really confusing me. Sorry if this isn't the best place to ask, I'm just pretty lost right now and could really use advice from someone who's really knowledgeable about this stuff, currently.

    Thanks all .

    I did a clean install on a laptop with an 8.0 Core OEM embedded key. Blank un partitioned un formatted drive. 10 Home was installed with no prompt to select Home or Pro, and no prompt to enter a key. Activated with a digital entitlement. showkey shows the installed key as the generic Home key. Settings > Update $ Security > Activation > Product key states "This PC is activated with a Digital Entitlement. This laptop was previously running 10 Pro upgraded from 8.1 Pro, with a digital entitlement. It now has digital entitlements for 10 Home and 10 Pro. I did a change key and entered the generic Pro key and it upgraded to Pro. Activated fine too.

    The latest release of the Windows 10 upgrade ( Fall Update Release ) will activate with a clean install and a Windows 8 key without having to upgrade first.

    I just installed a copy a day ago.
