Windows Embedded Compact 7 (codenamed Chelan), released on 1 March 2011, is the seventh major revision of the Windows CE embedded operating system.
With this release, the "CE" moniker was dropped from the name in favor of the expanded "Embedded Compact" title.
The Silverlight API has been introduced to allow easier design and use of fluid, "modern" UIs and programs. It is different from the traditional Silverlight.
An XAML API framework similar to (but not compatible with) Windows Presentation Foundation has been implemented to supplement the Silverlight API. It is possible to replace message boxes and the touch input panel with XAML variations.
A new window compositor has been implemented to enhance GWES (graphics, windowing, events server) with OpenGL to allow an assortment of effects to be used on windows such as alpha blending.
