When they say "upgrade your device" that implies that you are getting a NEW device, therefore, the free upgrade follows you, no matter what device you have.

 

Well I don't know. They could just force you to upgrade first, then let you have the option to do an upgrade on any system.

 

 

It doesnt make business sense to allow you to take an ISO from an upgrade, then use it to install a clean version of WIndows 10 on another device.   If they allowed that,  what would prevent someone upgrading a Win7 machine,  making the ISO,  then building a whole bunch of new machines,  never buying a OS for them?  

 

In the past they've got around the issue of a failed mother board or other replaced hardware,  you've had to call MS and get a new licence once they've established on the phone that you are genuinely replacing one broken/damaged with one new one       If you wanted to upgrade hardware, say a new motherboard,  that would invalidate the keys on your ISO I suspect they'll either say "NA UH   can't"  or have a phone call procedure that would still only enable that ISO to be on a single machine. 

 

Adobe do this by having their products periodically call up the validation server and get permission to run.   You can install Photoshop for example on two machines  (intended for your main machine at the office and your laptop to take with you on the road or when you go home) .    If you try to install it on a third,  it will invalidate them all,   and you'll have to revalidate any two the next time they start up and the third can run as a demo.

I think this idea was already cleared up.

 

It depends on what type of Windows you had before-- System Builder OEM or full, retail?

 

If you have OEM, then yes, you would have to call MS if you changed motherboards or whatever.

 

 

If you had W7 or 8.1 OEM/System Builder and you upgraded to W10 ONCE, then you could download the W10 ISO, install it on the new computer, use your W7/8.1 key for activation, then call MS to request more activations.

 

 

If you had W7 or 8.1 full, retail version and you upgraded to W10 ONCE, then you could download the W10 ISO, install it on the new computer, use your W7/8.1 key, and it would activate with no problems, so long as you don't have 2 computers using the same key at once.
