A must if you are serious about making programs for Windows.
The last PSDK release for current Windows versions was in Mars
and is called Windows® Server 2003 R2 Platform SDK
and has full content to help with both Win32 and Win64 development.
And just a few days ago (from the time of this post)
Microsoft Windows SDK for Beta 2
yep Windows Vista SDK, but just for the beta so API changes will most likely occur before Vista goes Gold.
However, if you stick to the 2003 R2 PSDK your programs should work without any issues on Vista as well (in theory at least).
Edit:
Could someone add the link above to the FAQ thread as well?
And if anyone notice future updates of the PSDK's please bump this thread .
