It seems that the only Windows SDK I can find is for the Feb CTP build. But the January build is the one that has the Go-Live license and therefore would be the one to use for development assuming you need the Go-Live license, which I do. My problem is that the only SDK build I can find is Feb, and that doesn't work with the January build of WinFx. Can anyone help me with this issue Where can I find the Jan build of the SDK
Thanks.

Windows SDK for January Build

we are planning to give Go live license for RCO(Next release),so you can develop your applications using FEB CTP,There are not many changes between FEB CTP object model and RC0 object model, so you can migrate your FEB CTP apps very easily to RCO
RCO may be available for download (This may change, right now we are thinking it may be available to customers in 1 or 2 weeks ) in next 1 or 2 weeks.
