Software Products Life Cycles

A common question, especially when working in legacy environments, is when will this product go out of support. I've always found this a pain to resolve as software companies are generally poor when publishing this information.

At least Microsoft have now addressed this with a very useful tool for answering this exact question.
Have a look at the Microsoft Product Lifecycle Search tool for more details.

If I find any more similar tools I will add them here as well.
