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.

Microsoft ended security-update support for Windows 7 on 14 January 2020.

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).

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 low user bases are decreasing constantly, making it less and less attractive to those parasites. The usage of Windows 7 will decrease more and more rapidly from its end of support from Microsoft on 14 January 2020.

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).

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