Vole killed off support for Windows 7 at this time last year and now Windows 8’s security updates will be coming to an end on the 12th of January, 2016.
This might seem a little strange as Windows 8 was only released in 2012, and Vole normally gives you a decade of support before killing it off. But this is more to do with the fact that Windows 8.1 is such a different beastie from Windows 8 that Microsoft is seeing them as different operating systems.
Given that Windows 8 was pretty pants, most users will have given up on it and upgraded anyway. Those who have not will not get support. If users upgrade to Windows 8.1 or even Windows 10, that support will be extended to 2023.
In addition to ending security updates for Windows 8, just last week Microsoft also announced that they will be ending support for older builds of Internet Explorer, namely versions 8, 9, and 10 which all come to an end also on the 12 January.
