Microsoft will end mainstream support for Windows 7 on January 13, 2015 for all version of Windows 7. Security patches and fixes will still be available until 2020, but there will be no more design or devlopment changes for Windows 7 after January 13, 2015.
Businesses that pay for extended support will still be honored until 2020 as well.
Thoughts?
I feel much more comfortable with this decision after Windows 8.1 was released. It really makes Windows 8 much better.
