Operating System Considerations
This unit ships without a pre-installed operating system, providing flexibility for users to install their preferred OS. No operating system configuration offers several advantages: freedom to choose between various Windows versions, Linux distributions, or other operating systems based on specific requirements; avoidance of unnecessary software licensing costs if existing licences are available; and clean installation without pre-loaded bloatware. The trade-off requires technical knowledge for OS installation and driver configuration. Windows operating systems provide broad software compatibility and familiar user interfaces, though newer versions may require additional hardware resources. Linux distributions offer free, secure alternatives with lower system requirements, excellent stability, and no licensing costs, though software compatibility differs from Windows environments.
