Windows 10: Windows 10 Install Questions

Hi, I am running Windows 10 and everything has been running fine. Then yesterday when I boot the computer, if appears to start asking me installation questions again, like what keyboard do I have, what is my location, and asks me to create an account name, tries to connect me to a network.If my PC is infected with something, I am afraid that it may be "reinstalling", and I'll lose files, etc. Why is it asking these questions again?Is there any utility or such that can at least let me browse my drive to see if anything was deleted? I created a boot USB, but it is trying to run the Windows 10

Installing Windows 10 on New PC?

I'm going to be building a new PC on Christmas and want to install Windows 10 on it. I have Windows 10 on my current PC, which I installed upgrading from 8.1 with the files on a USB. How do I go about installing a clean copy of Windows 10 on this new PC? I think I recall something about installing it once makes Microsoft recognize your hardware, but since this will be a PC I'm not sure what steps I need to take. Do I need to go 8.1 -> 10 or is there a method of going directly to 10?
