PC-BSD 7.1 is built upon the FreeBSD 7.1-STABLE operating system. FreeBSD is a UNIX-based operating system that provides a high level of security and stability. The Galileo Edition of PC-BSD includes updated versions of KDE (4.2.2) and Xorg (7.4). The latest version of KDE includes new window effects, screen savers, and better 3D Acceleration. PC-BSD exclusively features the Push Button Installer (PBI), a push-button software installation wizard with a wide range of applications. The latest version of the Push Button Installer improves PBI self-containment to increase reliability.

In addition to updated versions of KDE and Xorg, PC-BSD Galileo features many improvements and bug fixes that enhance PC-BSD's general ease of use:

• The new KDE 4 printer applet enables users to easily add and manage printers and print jobs without using the CUPS web interface.
• The Add / Remove Programs tool and the Update Manager have been consolidated into "Software & Updates."
• The Updater Tray has been modified into a small tray-only applet that shows users when updates are available. This is far less taxing on the CPU than its previous versions.
• FreeBSD ports and packages can now be created by utilizing the "runports" command.
• Greater stability for Flash 9 allows users to get higher quality from Flash sites such as Hulu and Youtube.
• Enhancements have been made to PC-BSD's System Installer, including upgrade functionality for those who wish to install PC-BSD while preserving their user data.
• Fixes have been made to bugs in the Wi-Fi and Networking tools, as well as to previous Linux Emulation problems.
