The online team has just added a great feature on the www.windowsembedded.com site. you now have a dedicated search that searches through all Microsoft content only for Embedded related content. You will find results from the MSDN Library, products information, Knowledgebase, Community (blogs, forums) and they will be sorted as technical or general results.
Give it a try, it is now easy to find information on Windows Embedded! And obviously, if you still can’t find a piece of information that you need, let us know so that we can optimize and fill in the gaps.
