ConclusionUI – modern (live tile) UIProgramming language - C/C++/C#/Visual Basic/XAML

Kernel – same as windows 8Multiprogramming – background / foreground

Multitasking – Fast App Switch/ResumeScheduling – Background AgentThread – preemptive(time slice)

Feedback 開發環境統一，方便於開發者 debug 或移植OS UI 布局較簡單， layout 設計不複雜 提供簡約風格，自成一格 許多 API 未開放給開發者，第三方程式發展受限Multitasking 的應用對於一般使用者較不友善
