Schenker install Windows 7 Home Premium 64bit on the system and they include SP1 as expected. Windows 8 is also an option when buying the system for those who would like the latest OS.
A minimal amount of software is installed at the factory, just the essentials like component drivers/software and some security software. We are left to get the browser, anti-virus and all other software ourselves which is as it should be on an enthusiast system.
Finally we have the BIOS which on this model uses Aptio code. There are no performance options present on this system however all of the standard items are available.
