Problemas com licença do Windows 8.
Right now your sister is abroad and you're transferring your SSD, HDD, and GPU into her PC. The main issue seems to be the different motherboard she uses. I'm wondering if this will still cause a problem when you return to your own PC with the original motherboard. You mentioned you won't have Windows 10 installed there.
You're handling things fine aside from the SSD. Of course you're not intending to reformat it and reinstall Windows. It should run, but it needs to be activated. If you're using a retail version, you're good to go! You can get it online or by calling Microsoft (free calls available in many areas), and you're all set. With an OEM version, it won't work. Sorry about that. Be aware that you might be tempted to claim the motherboard is faulty so they can activate it for you. But it could be tricky when you try to use the old board again. They could actually cancel your license and ask you to buy Windows if needed. This isn't just a breach—it's against the contract you signed with Microsoft (License Agreement). You might also lose your license if they flag it as pirated. You could technically use Windows on trial for a short time without activating it, but that's limited. I don’t know how long that lasts.
Isn't there a method to obtain Windows 10 at no cost for insiders or similar groups? Are these insiders only those who installed the Windows 10 versions? If that's the case, I'm happy on that point. Yes, it's true that OEM support is limited, and if you revert to the same hardware setup, there might not be any problems. (You might be mistaken—I know a lot more about this topic.)
This preview is still in development for regular users. As long as you install and maintain it, you receive Windows for free (with all the issues that come with beta testing). Using the OEM key may require phone activation. If asked whether you used it on just one computer and you confirm "Yes," it might label you as verified or something similar and send you to someone. Ultimately, how you share this with the other person depends on you. As long as you get the license back on the original device, you stay compliant with the license terms.
If you want to stay an insider after Windows 10 is officially released, then you have nothing to do. You'll continue with new builds and Windows updates to the path of Windows 10.1. If you want to opt out of Windows 10 insider preview once Windows 10 is released, then you can, only if you upgraded your previous Windows to Windows 10. If you did a clean install, then sadly, you need to install back your previous version of Windows and upgrade to 10. Be sure to do it before the free Windows 10 offer ends.
