Microsoft issued a reminder that mainstream support for Windows 7 is going to be shut down on January 13, 2015. What this means is that the software giant will no longer create new features or deliver other enhancements for the operating system like a new version of Internet Explorer. Security updates will be delivered until January 14, 2020, which is planned to be the end of Windows 7's extended support phase.
The bulletin also points out that mainstream support for Windows Server 2008 and 2008 R2 will be ending in January 2015 as well and that Windows Phone 7.8 will move to extended support on September 9, 2014.
Windows 8.x on the other hand receives mainstream support until January 9, 2018 and extended support until January 10, 2023.
