Do I need to purchase Windows 10 again?

[markymoo]

I own Windows 7 Pro (boxed version, not OEM)
I upgraded for free to Windows 10
I have since changed graphics card, processor and memory, no isssues.
However, I wondered where I would be for a full system upgrade?

Am I stuck with Windows 7 Pro (as the free upgrade to 10 has expired)
The W7 Pro Code will work for installing W10
Or do I have to purchase Windows 10 again?

Thanks in advance. Just need to know if I need to factor the payment of an OS into my next build?

Beginning with the Windows 10 Anniversary Update, you can link your Microsoft account (MSA) with the Windows 10 digital license on your device. The new feature allows you to access the Activation Troubleshooter quickly to re-activate your free upgrade copy of Windows 10.

If it's a retail 7 pro key, then it will work as a 10 pro key. Did this myself over a year ago and my 7 pro key activated 10 pro without any issues.

Excellent, so do I have to download Windows 10 and burn to a disk?
Or can you install Windows from a USB Stick?
Then on my new build I just enter the Pro Licence Key and good to go?

Thanks for the feedback labcoattech and orcvader nice to know that extra hundred quid can go towards the build

You can install from a USB, the Windows 10 downloader will even offer to make a bootable USB.

Yup, when it asks for a key, just plug in the 7 key and you're good to go.

You can download the ISO and create USB installation media using the tool on the following Microsoft website,
