KIS license for one PC: new installation of Windows

[Guest]

I am looking for a security suite which does not require an account. From what I have read in the forum: I can buy a boxed Key in a computer store and install the product without registering an account.

 When I reinstall Windows 10 on my PC it will not ask for Windows 10 key and it will activate itself automatically. 
 But after the fresh install of Windows I would obviously need to install Kaspersky Internet Security again. Will it then ask for the respective product key? If it will - and if I would need to provide it again could it lead to problems/not activation? 
thank you :)
