O-T

I'll just point you to a video Linus and Co. published a while ago: 
 

Cool guide but it seems like it might be broken since the only association I can manage to get working with my discord is through the forums, not through the floatplane site. Might want to look into that for floatplane-only users.

Testing new builds and their deployment on a few different machines is an example.

You might as well try to give him your old key, just cross your fingers and hope that it is re-usable (if it's official, then it should very well be re-usable) and not digitally activated on your hardware (but since you got the key that doesn't seem to be the case).

I don't see what's wrong? Windows Pro shows that it is activated by a license provided by your Microsoft account, which is what it's meant to do if you bought Windows 10 Pro on your MS account.
 
As for the software showing the old key, I'd guess that it's just because that software doesn't know how to display the fact that's it's digitally activated now and so displays the last key it saw.

I have a lot of spare time to kill, so I'll be sure to contribute pretty much as much as I can! I was actually not sure if this channel enabled the community subtitle contribution ability or not, so hadn't really bothered looking into that, now I will Won't hurt to have French translations too, haha!

I agree on the French part. I'm myself native, and a few of my friends are able to watch videos fairly easily by trying a bit, it is true that French content is in limited quantity, but people here just get used to learning enough English to understand the videos they're watching anyway. So reaching out to other audiences instead wouldn't be a bad idea.
In fact, @nicklmg, if you need French translators, I'm down for that, I'm bilingual, if that's something you need.

I believe that's an option you have to set in power options in your control panel. If I recall correctly, you have to select the high performance profile while on battery and it should get you running.

CPU swaps don't need a reinstall, just take the old cpu drivers out and get the new ones.
 
Edit: As other forum members have kindly made me noticed, I completely missed the Motherboard swap that was involved and didn't think about it, skip this comment and read on. As well as a typo in the message, I meant chipset drivers either way (Yes, I know, chipset drivers are motherboard-orientated, not CPU), not cpu drivers.

No, the system is not made in such a way where graphics drivers are at factory state. When you reset your PC, all you have to do is grab the graphics drivers again from the web for your equipment by doing a quick research. However, I believe that nowadays Windows 10 fetches a lot of the drivers almost automatically. The enterprise that sets up the PC is responsible for loading the drivers on the OS.

I've always kind of just upgraded and revamped my whole setup every two years. This is payback for not doing it at the 2 year mark this year, lol. 

Oh well, I think it's time to start fresh. New 8700k, 1080, etc. 

Thanks my dude.
