Question Windows 10 installed on new motherboard?

[SkyRock1986]

I have a cd copy of Windows 10 that I purchased through pcpartpicker.com. My question is I am upgrading to a AMD motherboard from a 1150 so I can upgrade my CPU from a 15 4690k to a Ryzen 5 2600x, will I need to buy windows again? If not, how do I deactivate windows so I will work on my new build?

The OS is currently installed wit hthe 4690k system, and you're moving to the Ryzen 5?
Should be no problem

For the OS activation, read and do this before you change any parts:
https://support.microsoft.com/en-us/help/20530/windows-10-reactivating-after-hardware-change

Windows build 1607 and Activation

So, the Anniversary release is out, and many people have updated their machines. Interesting changes with activation and hardware changes. Specifically, the Activation troubleshooter: https://support.microsoft.com/en-us/help/20527/windows-... You must link your OS license with your MS account...

That's just for the licensing.
You may still need to do a full wipe and reinstall with the new hardware.

I plan to do the full wipe and reinstall with new hardware anyhow... That way there is no driver bugs. But by upgrading cpus I had to change to a whole new motherboard. How can I tell if my activation key is reusable?

I know some keys are only reusable I believe on the same motherboard only??

Go through the links I posted above. If it is an OS license that you purchased and installed, it is almost certainly able to transfer to new hardware.
You just have to go through the right steps.
