Microsoft has officially announced it will cease to support Internet Explorer 8, 9 and 10 from January 12. The company will issue a Windows update KB3123303, which will place a prompt box in the three browsers urging people to update to Internet Explorer 11. This will happen for Windows 7 and Server 2008 R2 users.
The box can be disabled by enterprise users who don't want to jump ship by altering the registry. However, switching to Internet Explorer 11 is far the better option in the long run.
The end of life status for the Internet Explorer 8, 9 and 10 means that Microsoft won't release any more security patches, leaving the browsers vulnerable to potential new threats. This way it hopes users will move on to a more recent version of the browser, hopefully Edge.
