I have a boxed copy of Windows 7 Ultimate. A long time ago, I upgraded to Win 10 using one of the upgrade paths from within Windows (can't remember which one exactly). It caused some issues and I reverted to Win 7.
After some time, I decided to give it another go. I ended up using my MSDN license to download an installer and used that to install Win 10.
What I want to do now is to use my own license to reinstall Win 10. As I understand it, this is possible (I have had a look at this question). My situation is a bit different though because I want to do this as part of a computer upgrade, where I'll be replacing pretty much every component apart from the PSU.
Is it still possible to upgrade even though the hardware configuration is changing? If it is, do I need to first install Win 7 on the new computer, then upgrade to Win 10, and then redo the Win 10 installation from fresh to get a clean install, as implied in this question?
1The original Windows 10 install will not survive this major upgrade from the point of view of licensing which is why you need to start over with Windows 7 and then see if you can upgrade – John – 2019-11-05T22:37:44.343
What is or isn't possible entirely depends if the Windows 7 is a Retail or OEM license. Please edit your question to include this vital information required to submit an accurate helpful answer. – Ramhound – 2019-11-05T23:12:22.937

Possible duplicate of Can I transfer a Windows 10 licence to my new PC if it was upgraded from a retail licence?. Please see the possible duplicate for more information about installing Windows 10 on a new build with an existing Windows license. It is debatable if the upgrade offer (which has expired) applies to a new build in 2019, technically the upgrade offer was for the machine, not the license itself.
– Ramhound – 2019-11-05T23:17:31.513@Ramhound I've updated the question, though you seem to have seen the relevant update in one of my comments. What I'd be interested to know is, since I've taken the upgrade offer the first time I upgraded from Win 7 to Win 10, would it allow me to install Win 10 using my license. One of your comments here suggests so. I will be sure to read your related answers to other questions later. – Moss – 2019-11-06T12:29:18.127
@Moss - Debatable considering the upgrade offer expired 2 years ago. – Ramhound – 2019-11-06T12:30:44.473
@Ramhound Hmmm. My thinking was that I did take up the offer originally, despite later reverting to Win 7. Also your comment Tonny's answer seems to suggest that you agree that I should just be able to bypass all these issues and just install a fresh copy of Win 10 simply by using my original Win 7 key. So I'm a bit confused as to what I can or cannot do. – Moss – 2019-11-06T13:15:52.993
2You indicated you upgraded your current computer but you want to use it on a new build. The offer was for the machine not the license – Ramhound – 2019-11-06T13:49:06.700
