Microsoft support life-cycles for Windows and its other software
Note that extended security support for Windows XP from Microsoft ended on April 8, 2014. There is nothing to stop anyone from continuing to use XP, which, in April 2016, still ran about 7.46% of all desktop and laptop computers. Due to its relatively low user base, Windows XP is now much less unlikely to be targeted by cyber criminals. Moreover, that user base is decreasing constantly, making it less and less attractive to those parasites.
Windows 10 was officially released on July 29, 2015. By April 2016 Windows 10 was running an estimated 17.90% of all desktop and laptop computers. The percentages in April 2016 for Windows 7 and Windows 8.1 were 44.56% and 10.30% respectively. Android machines were not included in the data, no doubt because it is used almost entirely on tablets and phones. Android is an open-source development of Linux by Google. The percentage of PCs running other versions of Linux was only 1.55%.
Microsoft will be ending extended security support for Windows 7 SP1 on January 14, 2020.
