The tech support guys is obviously not sure of what's going on.

I don't think it works like that. On my own experience, I did the free upgrade last week to my HDD when it came out. I also created a USB drive to do a clean install, during the weekend I replaced the HDD with an SSD and put a new RAM stick in it. Windows 10 was installed from the USB stick and was properly activated with those hardware changes without having to input any type of product Key.

So yeah, bad on the tech support guy, but I don't think this will be an issue for gamers who constantly change RAM, video cards and hard drives.
