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 Windows XP, which, in June 2017, still ran about 4.0% of all desktop and laptop computers used to access the web (3.2% by February 2018). See the chart below of the operating systems used to access the web in February 2018.

Due to their relatively low user bases, Windows XP and Windows 8.1 are now much less likely targets of cyber criminals than Windows 7 and Windows 10. Moreover, those user bases are decreasing constantly, making it less and less attractive to those parasites. Windows 7 and Windows 10 are the dominant versions of Windows, as can be seen in the chart below.

The official release date of Windows 10 was July 29, 2015. By June 2017, Windows 10 was running an estimated 30.87% of all desktop and laptop computers (43.53% in February 2018).

The data does not include devices that use the mobile Android operating system, no doubt because the use of Android is almost entirely on tablets and phones. Android is an open-source development of Linux by Google.

Microsoft will be ending extended security support for Windows 7 SP1 on January 14, 2020.
