Microsoft is to add to its flagship Security Essentials tool with a "secure boot" feature, designed to combat infected USBs flash memory and/or so-called boot-kits.
For new systems that support UEFI 2.3.1 specification, they can only be boot up when a validated code coupling with the system firmware, ensuring malware cannot load during boot or resuming processes.
What is UEFI specification?
In a nutshell "UEFI stands for "Unified Extensible Firmware Interface". The UEFI specification defines a new model for the interface between personal-computer operating systems and platform firmware. The interface consists of data tables that contain platform-related information, plus boot and runtime service calls that are available to the operating system and its loader. Together, these provide a standard environment for booting an operating system and running pre-boot applications. "
Whilst this is a welcome new, one must be aware that this new and improved security mechanism could also block out the ability to install an alternative OS or even downgrading / upgrading the current OS version, unless systems manufacturers take step to implement a turn-off option in the BIOS.
So, look to get a Windows 8 system in the future? Pay attention to which brands that offers this on-off switch, if you want to install alternative OS
cheers ...
