Windows 10: Win 10 licence question

I own a retail copy of Win 7 Home Premium, for which I still have the DVD and licence key. I upgraded to Win 10 during the free period. I am building a new PC, and am trying to work out if I can transfer the licence for Win 10 from my old PC to the new build.

I have three separate answers from Microsoft support chat, depending on which customer support person I speak to:
1. Yes, I own a Win 10 licence which may be transferred between machines.
2. My Win 10 licence is tied to a single machine. I can install Win 7 on the new machine, but not 10.
3. I can transfer Win 10 to a new machine, but only if my old one is ‘broken’ (how would MS even verify this?). I told customer support I would be happy to snap my old motherboard, but he did not seem amused.

Advice on various Internet forums is also conflicting. Has anyone done this succesfully, and if so can you point to a set of instructions?


I’m reluctant to just go ahead with the build, install Win 10 and see what happens, because my new machine will canibalise some parts from the old, and it would be painful if I have to rebuild the old machine to attempt some form of de-activation.

Get a Windows 10 licence for free if you register on Windows Insider

Yeah.

I installed the preview on 3 computers and I have 2xWin8 pro and 1xWin8 pro WMC licences already. I'm wondering if there will be a way to convert my Win 8 licences to Win 10 ones without having to install the full OS and go through the upgrade route.

I'm also hoping that my retail license will remain retail as I plan to upgrade a little after skylake is released.
