How long is it supported by Microsoft ?
I get this question routinely from customers ... with "it" being whatever product or solution is in question (Office 97, Windows XP, SQL Server 2003, etc). We have a great site at Microsoft Lifecycle Support Policy that explains the support schedule around just about any product, including information around the various "phases" of support begin and end.
The Microsoft Support Lifecycle policy provides consistent and predictable guidelines for product support availability when a product releases and throughout that product’s life. By
understanding the product support available, customers are better able to maximize the management of their IT investments and strategically plan for a successful IT future.
