Windows 10: Can spyware be installed on windows 10 in s mode

Hi, I am very untechie, but have found myself in a situation that is causing me some concern and need advice from people in the know. I left my laptop on and unattended for about 1 hours as i did the school run, however i had workmen in at the time. Now i have this nagging concern that while it was on and unattended someone could have installed something on my device. I read so much about spyware etc that i am now worried, but possibly overthinking. My laptop is running windows 10 in s mode. Thank you, J

:)

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?
