Microsoft made available for download on September 1 a public test build of the embedded version of its Windows 7 platform — known officially as Windows Embedded Standard 2011
and codenamed “Quebec.”
(The Community Technology Preview bits of Embedded Standard 2011
are available on Microsoft’s Connect site.)
Windows Embedded Standard is targeted at OEMs and specialized device makers who want to build platforms and applications that use various Windows components. In other words, it is the componentized version of Windows 7.
