Activation after hardware change

[computation]

Hello, 3 week ago, I replaced my x570 motherboard because it broke down. I replaced it with x870 and  i also replaced my ram and cpu. 

Windows has not asked for activation,  but I havent connected my pc to the internet.

In the event that windows ask for activation, how I do I activate? 

My windows is window 10 pro retail that comes with product key. I haven't created a microsoft account as far as i can remember

Since it's a retail key you should be able to reenter the product key and it will activate on the new hardware. It's the OEM licenses that you have to be careful with since those can end up locked to a specific board.

Thanks, hopefully the reactivation goes  without a problem.
