Cory was talking about "WinRT". I presume he means Windows RT.
"WinRT"
is an API, not an OS, but it's a common mistake.
Windows RT is the ARM version of Windows 8. As such, what Windows does
on Intel is irrelevant; Windows RT doesn't run on Intel or x86, *only*
on ARM.
On ARM Windows systems, UEFI is mandatory and in that UEFI, SecureBoot
is hardwired ON. You cannot disable it or turn it off. This is an MS
stipulation; no-one can sell ARM machines for Windows unless
SecureBoot is irrevocably and permanently switched on.
