The desktop gadget style of app for Windows, first introduced in Windows Vista, may be on the way out for Windows 8. Even though support for these kinds of programs was put into the Windows 8 Consumer and Release Preview builds, newly leaked information claims that the current, but unreleased, versions of Windows 8 have removed support for such programs.
Win8China.com reportedly got a hold of these unreleased Windows 8 builds and claims that support for desktop gadgets is no longer present in the build's control panel. The HTML-based desktop gadgets, sometimes referred to as widgets, are also not supported in the desktop modes for Windows 8, according to the article.
