Unsigned code running on Windows

We haven’t seen very much about the Windows RT package, so it’s nice to hear [Clrokr's] thoughts on it. As far as he can tell the system has not been watered down from its Intel-aimed (x86) counterpart. Rather, RT seems to be a direct port with what is called “Code Integrity” mechanisms switched on. There is a kernel-level setting, barricaded behind UEFI’s Secure Boot, which determines the minimum software signing level allowed to run on the device. This is set to zero on a Windows 8 machine, but defaults to 8 on an ARM device. [Clrokr] uses a debugger to insert the code seen above into a DLL file in order to reset that minimum signing value to 0.
