In all fairness, Windows XP is still a relatively widely-used operating system and is also quite old, as far as software is concerned. And Microsoft also gave plenty of warning — years worth — that they were going to end support. They said that customers should just move on, with the popular Windows 7 and Windows 8 as worthy options for any upgrader. Or a new computer.
That said, the update that Microsoft issued for XP two weeks ago was for a critical "0-day" vulnerability in Internet Explorer, a vulnerability that could be traced all the way back to Internet Explorer 6 and still existed in version 11.
But that's it. No more. So says Microsoft:
If you're still on Windows XP, you won't receive any security or non-security updates through Windows Update or Microsoft Update. Support ended for Windows XP April 8. If you continue to use Windows XP without support, your computer will still likely work -- but it will become vulnerable to security risks and over time, its performance will be affected.
But the rest of you are done.
