Do i need to reinstall Windows after a change of Motherboard and CPU?

[p9trov]

So, I've heard many opinions some say that you are required as you just wont boot up into windows and other mention that its not required and you will need to just uninstall previous motherboard drivers before the motherboard swap. I don't want to try yet as there are some files on my HDD which I will transfer but not until next week as my buddy is coming around with his portable HDD.

My main question is I am changing from a 2500k / Z68 motherboard to 6700k and Z170 (running windows 10 atm), both motherboards are Gigabyte if that makes any difference. The thing is at this stage im not keen on reinstalling windows as I will be getting an SSD replacement with a bigger capacity down the line so I would love it if I could just in terms Plug and Play the new motherboard and CPU. 

Any help will be greatly appreciated.

What I would recommend us to uninstall the past drivers from your old hardware if possible. But make sure you have installed the correct drivers for your new hardware

Every time I've switched motherboards/CPU the old OS works fine without any changes. I've gone from AMD to Intel and had my Windows 10 installation still work, I've gone from a system with DDR3 to a system with DDR2 and it's still worked, and a few other times

If you use paragon adaptive restore, you can use the existing OS

First thank you for the kind replies and suggestions. What i would like to ask is the paragon likely to screw up any software or files (in the sense of just not be able to launch the app and have to locate its directory in shortcuts etc)? 

Other than that I would straight up give the paragon a go and not risk trying without doing it.

Not really, just uninstall the old drivers and install the new ones.
