I am upgrading most of my rig and am wondering how the procedure will go.
I am changing my motherboard, RAM, and CPU.
The only things staying the same are the storage drives 2 SSD's and 2 HDD's (with the OS on 1 of the SSD's) and the graphics card, an EVGA GTX 1070.
I am going from an Intel 4690k to a 7700k and from a Z97X-SLI gigabyte board to a Z270 asus board and the ram is going from Crucial Ballistix DDR3 4x4 to GSkill TridentZ DDR4 2x8.

So as far as the initial boot, will I be able to start it just like before? Will I need to reinstall my OS, or no? I'm more or less asking with all those pieces changing what will happen when I turn on the new rig (assuming there are no issues)? Just trying to make sure I don't run into any unexpected surprises when I start trying to make the changes.

So, read this https://scottiestech.info/2010/03/17/upgrade-your-motherboard-without-reinstalling-your-os/

Making the sure the computer will boot with the new motherboard will be the biggest thing. Your CPU and RAM won't really make a difference.

But, there's something else to take into consideration. Windows will de-activate after so many hardware changes, and will likely happen with yours. If you're on Win10 read this https://scottiestech.info/2017/02/26/upgrade-your-motherboard-without-reinstalling-windows-10/

So I read both of those pages, and ran through the steps of the first one up until actually changing anything, so I'll be able to repeat those steps again most likely. As for my windows it was 8 that came with my previous laptop and I used the free upgrade to windows 10 but recorded the old Windows 8 key then used that key to get Windows 8 on my desktop PC, then upgraded that to Windows 10 as well (Sort of a round-about way but hey I have 2 devices with legit Windows 10 and didn't pay a cent as the laptop was second-hand). So what would happen in that case? For the W10 specific steps my OS is already linked to an over-arching Microsoft account, so that means I should be good right? I think so based off those articles and that I'm still on both Intel and Windows for my platforms. Oh and you said that Windows deactivates after a certain number of times changing hardware, for me this is the first time since setting up that I'm changing hardware (beside going from a HDD to a SSD for my OS and changing my CPU cooler to an aftermarket variant)

Shouldn't have said might deactivate. It will deactivate on changing the motherboard, no two ways around it. As for the key thing, the same rules apply, because the reactivation will look at the original key from the original installation, not the one given to Win10 after the upgrade. (figured this out the hard way). If I read that right, you used the Win8 key for your laptop (OEM) to install Windows on your desktop, which means that upon de-activation, you will not be able to reactivate it.

So when you buy a computer from a store like BestBuy or Walmart as an example and it comes installed with Windows, those copies are OEM? I only ask because that's the origin point of the first copy and after that they are all free upgrades to W10. Are the free upgrade versions not retail?

Yes, if you bought a machine with Windows pre-installed, the key in use is OEM. I'm not sure how exactly the key is generated for the free upgrade, but I do know (personal experience, found out the hard way) that when your Win10 copy is de-activated, you lose the right to re-activation because the re-activation will look at the old (OEM) key as it stored in the computer. On an OEM machine, the key is only valid for the hardware configuration that was present when the key was installed. Little changes generally won't trip the re-activation (e.g. GPU, CPU, RAM, HDD) up to a point, but when you replace the motherboard, as far as Windows is concerned it is a whole new computer.

So to sum it, because the original key you used on your machine, was an OEM key, when you replace the motherboard your Win10 copy will deactivate, and you will be unable to reactive it without purchasing a new key. (well, there is another way, but discussing such things on Tom's is highly frowned upon).

As long as I can boot it into Windows, and then activate it afterwards (I'm guessing there would be a time-frame for this) then I'm fine with that, may as well finally get a retail copy of W10. Thanks for all your help, at the end of all my research into an upgrade this was my last question still unanswered, looks like I'm all set.
