For legal purposes, I have decided to rename Fuji OS into UXOS Cupertino, and I have also renamed Lindows/LindOS into UXOS Redmond.
UXOS Redmond was designed to maintain a look and feel which should be familiar to users of Windows.
UXOS Cupertino was designed to maintain a look and feel which should be familiar to users of macOS.
UXOS Redmond is considered a general-purpose OS with all the necessary software the average computer user would want with several web browsers, email, social media (Twitter and Instagram), chatting (Skype and Pidgin), watching videos (VLC and Totem), gaming (including several retro console emulators), and listening to music (including Spotify and Rhythmbox and a YouTube music player called Headset).
UXOS Cupertino is a more advanced system designed for both general purpose users and serious users. UXOS Cupertino includes the same features as UXOS Redmond, however UXOS Cupertino also includes several creativity applications (including Blender and Inkscape) and Oracle VM VirtualBox.
Both UXOS Redmond and UXOS Cupertino include the Linux 4.11 kernel.
Both are available for free.
