It is important that you know how long you will get support from
manufacturer when you purchase licensed product. Here I would like to share the
product life cycle of Microsoft products.
The product lifecycle of Microsoft is divided into
mainstream support and extended support. Mainstream support is the first phase
of the product support lifecycle. It covers both security and non-security
updates for the operating system, as well as complimentary support that is
included with the license and paid support. The extended support phase provides
users of the operating system with security updates, and paid support is
available as well.
The Windows XP and Windows Vista operating systems for
instance are currently in the extended support phase, while Windows 7 and
Windows 8 are in the mainstream support phase.
