Today we're launching a new resource page in support of Windows XP Service Pack 2. The blurb from the page explains what it's all about:
Windows XP Service Pack 2 Security Information for Developers
With Windows XP Service Pack 2 (SP2), Microsoft is introducing a set of security technologies that will improve Windows XP-based computers' ability to withstand malicious attacks from viruses and worms... ...To developers these technologies will have impacts on the applications that they create and the tools they use. This page contains resources to assist developers in dealing with these impacts.
We'll update that page as more information comes available in the next few weeks. Windows XP SP2 has been the number one search on the Security Developer Center for some time now and we hope that this new page helps developers find the information they need.
