Redmond-based software giant Microsoft Corp. has recently updated its support policy for both Windows Vista and Windows 7 and will be offering extended support to the consumer versions of the two operating systems.

Previously, Microsoft provided 5 years worth of 'mainstream support' for consumers while only businesses got an extra 5 years of extended support. Now, all Windows users will be able to get security updates for 10 years after the operating system's release.

As a result of the policy change, Windows Vista's consumer support was extended to April 11th, 2017. Windows 7 support will end on January 14, 2020. (Source)
