Microsoft is reminding Windows 7 users that support for Windows 7 RTM ends on April 9, 2013, so its time to install the service pack.
For those who are updated, there is no need to worry. Windows 7 will continue to be fully supported for a long time, with mainstream support continuing until January 13, 2015, and extended support continuing until January 14, 2020.
Windows 7 Service Pack 1 can be downloaded from Microsoft.com
For the difference between Mainstream Support and Extended Support, view the chart below.
