Windows 8.1

Microsoft has decided, after over 10 years, to stop offering the public any advance previews of software security bulletins the company plans to release as part of its monthly "Patch Tuesday" event, which happens on the second Tuesday of every month. In a statement, Microsoft said it will continue to offer its Advance Notification Service (ANS) "directly to Premier customers and current organizations involved in our security programs."

Why the change? Microsoft stated:

"ANS has always been optimized for large organizations. However, customer feedback indicates that many of our large customers no longer use ANS in the same way they did in the past due to optimized testing and deployment methodologies. While some customers still rely on ANS, the vast majority wait for Update Tuesday, or take no action, allowing updates to occur automatically. More and more customers today are seeking to cut through the clutter and obtain security information tailored to their organizations. Rather than using ANS to help plan security update deployments, customers are increasingly turning to Microsoft Update and security update management tools such as Windows Server Update Service to help organize and prioritize deployment. Customers are also moving to cloud-based systems, which provide continuous updating."
