Windows 10: Upgrading a Cloned Windows 8.1 SSD

How do you activate a non OEM W10 when you upgrade your hardware or build a new system?

I've upgraded a retail Win7 OS to W10 Home and it's activated, according to the EULA I can use that same activated OS to install on my system when I upgrade my MB and/or CPU and/or whatever other hardware needs replacing. Or if I build an entirely new system, how do I go about showing my W10 activated OS is no longer on a retired/replaced system.

Below is for the OP

I guess if you go back to the previous OS within 31 days your activated W10 would revert to your previous qualifying OS.

Apparently going back to your previous OS, or performing a clean install are the only things left to do.

 

This sounds logical so I'm thinking I'll just leave well enough alone and stick with W8.1 on my SSD installing my original HDD with W10 every once in a while for updates and if I absolutely have to re-clone my SSD to W10 from my HDD.

Thanks for you input everyone!

 

You re-install and activate your qualifying license and upgrade again. You can't transfer the Windows 10 install to another PC as it will have a different hardware hash. This will only be free for the first year. After that you'll have to buy 10 or revert to your previous OS if you change hardware (at least that is what they are saying now).

You don't have to. If you activate 7 by phone you'll have to say how many machines it is running on so unless you want to lie you have to uninstall (or stop using) the other version. Same as before - you don't unregister - you just stop using it.

No it wouldn't. You can restore back to a 8.1 backup at any time. The 31 days is only for the option for doing it from within Windows 10. Once you have upgraded that hardware to 10 and seen it is activated then that device is registered. You can then clean install or upgrade at any point during the lifetime of the device.

You could therefore upgrade to 10, revert to 8.1 backup after 6 months, run 8.1 until end of life in 2018 and then upgrade or clean install 10 because your device is already registered on MS servers.

No. You can clone your HDD to SSD or you can upgrade the SSD using the ISO or media creation tool. If your Windows 10 is activated on your HDD then it makes no difference.

If you decide to use your SSD then Windows 8.1 will remain activated (forever) but if you (ever) upgrade it to 10 or clean install 10 that will be activated also as long as you are on the same device.

If you want to upgrade, the easiest is to copy the ISO to your desktop, mount it and click on set-up.exe. (Option 5 in this tutorial: Windows 10 - Upgrade Installation - Windows 10 Forums )

You can make an iso using media creation tool or download one. See here : Windows 10 ISO Download - Windows 10 Forums

Getting an ISO is better than upgrading direct as if something goes wrong you don't have to download the whole thing again.

 

I'm not reinstalling Win7 and activating it by phone, I no longer use Win7. This computer is now a W10 machine upgraded from a retail license.

See section 4, subsection b, in the EULA, this document below is from my current install of W10 Home. This addresses upgrading from "stand alone" software which I did. Might have to use the Win7 License that I upgraded from to activate an install of W10 in an upgraded, or rebuilt machine, at this point nobody can say for sure how this will work out. I do know I can't use the Win7 license I upgraded from to install Win7 in any computer without violating the W10 EULA while using the W10 upgrade software.

 

Thank you halasz.
I was thinking I could do what you're saying but wanted to confirm and with the different answers I was getting I just wasn't sure.
