Microsoft is starting to notify customers about the upcoming support deadlines for some of its popular software products, according to ZDNet.

Microsoft's product life cycle has three phases: Mainstream Support (which typically lasts five years), Extended support (another five years of software fixes and security updates) and End of Support.
Feature software updates and patches are usually given to products covered by Mainstream Support. After that, Microsoft will continue to offer bug fixes. But once the Extended Support expires, that means the end. End of Support simply means that your product will no longer be supported.
Microsoft recently published a list of expiring products on its official support page. Among them is Windows 7 (Starter, Home, Professional, Enterprise, Ultimate) which will exit the Mainstream Support period on January 13, 2015.
Meanwhile, Microsoft's old mobile OS, Windows Phone 7.8, will end its Mainstream Support on September 9 this year.
Products moving to the End of Support phase will include Microsoft Office 2010, Visual Studio 2012 (Remote Tools and Test Professional), and Visual Studio Express 2012 (Web, Windows 8, and Windows Desktop). You can check out the full list here.
