jones_supa writes with this news from Ars Technica: "Windows 7 users will have to install Service Pack 1 if they want to continue to receive security fixes and other support beyond April 9th. With the release of a Service Pack, Microsoft's policy is to support the old version for two years. Windows 7 Service Pack 1 was released on 22nd February, 2011, so the phasing out of support is happening more or less on schedule. In spite of a growing number of post-Service Pack 1 fixes and updates, Microsoft has shown no signs of shipping a second Service Pack. Should Service Pack 1 be the sole major update for Windows 7, it will continue to receive mainstream support — which encompasses both security updates, non-security bugfixes, and free phone support — until 13th January 2015. Extended support — security fixes and paid incidents only — will continue until 14th January 2020."
