Windows Embedded? Windows CE? Windows Mobile? I must admit I lost track long ago of which Windows is what in the mobile and/or embedded space, but fact is Microsoft is working hard on bringing new releases in those spaces. It's working on a new Windows XP-based Windows Embedded release, dubbed Windows Embedded Standard 2009, but the company is also working on a Windows Vista-based embedded release
According to Mary Jo Foley, this Vista-based embedded Windows is codenamed "Quebec", and boasts quite a set of new features:
The forthcoming Quebec embedded release will include BitLocker drive encryption, Windows Firewall, Windows Defender, Address-Space Load Randomization - and on the memory-management front, support for SuperFetch, ReadyBoost and Dynamic System Address Space. On certain devices, the Quebec release will also provide as optional components Aero user-interface, Windows Media Player 11 and various Internet Explorer 7 features. Unlike Microsoft's XP-based embedded releases, which are 32-bit only, Quebec will support both 32-bit x86 and 64-bit x64 processors.
There also appear to be a number of downsides, one of them being rather unsurprising: where Windows XP Embedded minimum size takes up about 40MB, the Vista variant will eat roughly 300MB - that's without all the optional components. In addition, you will need to activate this new variant. Quebec is scheduled for a 2010 release.
Something tells me will see "Save XP Embedded!" petitions in the future.
