On my X1 Carbon, I had to go into the BIOS and disable "secure boot" in order to even boot from a Linux Live USB drive. That would already deter a good number of people from even trying. I hope things don't get any worse.
I wonder if any kind of antitrust case could be made against Microsoft for this, as it's clearly putting an impediment in the way of installing other operating systems.. and this is a form of anti-competitive behavior.
Personally, I think having to specifically enable boot-from-USB in the BIOS is a very valuable security measure. However, I do support the ability of everyone to control their own PC.

I'm just saying I find it much more involved than changing a simple BIOS setting.

Very simple.
