Based on AlmaLinux, the operating system — which is the successor to Oreon Lime — has been designed with simplicity and familiarity in mind, bridging the gap between the ease of use people expect from Windows and the power and flexibility of Linux.

The brand new operating system sports an intuitive interface that will be instantly recognizable to Windows users, and it offers seamless compatibility with popular applications, and solid performance. Oreon 10 promises to make transitioning to a Linux environment not only approachable but (whisper it!) enjoyable.
