Windows 10: Windows 10 Upgrade Install CD Key and/or boot requirements

I tried to install Windows 10 Pro 32 using a DVD .. and, booting from the DVD.
When I got to the point where the Key was needed, it didn't accept the key.
(I used the Windows 7 Pro 32 key that the machine already had for lack of any other).
I read something that suggested one must do this from within Windows. So, I did that.
It didn't ask for a key and it worked.

Yet, I wonder if the other process should have worked?
The machine is an MS Refurbisher build of Windows 7 on an original Vista machine.
Here is the Belarc Advisor info:




The footnote to the first one says:




This seems a bit odd because the Product Key with "OEM" lines up with the DVD Key I was using. Yet, it appears to say Microsoft - Internet Explorer.
The one lined up with Windows 8.1 Professional isn't one that I recognize at all.

Should one be able to install by booting from the Windows 10 DVD?
Does the fact that it's a Refurbisher install matter? (Presumably that's just a newer OEM install).
Does the fact that it's based on an OEM Vista system matter?
Is there a better tool than Belarc Advisor?

Windows 10 Product Key after upgrading to Windows 10

Yes, Boot Camp installs of Windows 10 alongside Mac OS X will require a Windows 10 product key to install and activate. If you already have Windows 7 SP1 or 8.1 installed in Boot Camp, you'll be able to use the free upgrade offered for Windows 10. However,
a clean install within Boot Camp will require you to buy a copy of Windows 10.

 

windows 10

during win10 upgrade do i require a CD key for installing

 

You can clean install by booting; upgrade must be done within the OS. Need to upgrade prior to doing a clean install. When asked for a key just skip that step and it should activate upon boot.
