I though I’d take a few moments to write about this topic. As many of you know, April 8th, 2014 has been set as the date when Windows XP extended support will end. So what will happen to existing Windows XP installations as there are still at least 10% of Windows XP installations out there. It may not seem much but it is millions of users.
After the given date, Microsoft will stop publishing security updates for Windows XP which are distributed through the Windows Update system. This means, security patches for the discovered security issues with Windows won’t be published anymore. Of course, the Windows XP won’t stop working after April 8th, but your system could quickly become compromised by malware.
Here is a mechanism hackers will abuse – once a security issue is patched within Windows 7 or Windows 8 and published through Windows Update, hackers will check for these updates, reverse engineer them and check if some of the security issues are shared with Windows XP. If they discover they are, they will attempt to create a so called 0-day vulnerability and as there won’t be no more security updates the vulnerability will essentially stay there forever. As Microsoft publishes patches every Tuesday, this may happen sooner than you may expect. Microsoft will start showing warning dialog on March 8th notifying users of the end of support.
Some sites have reported that the support for anti-malware will be extended to 2015. One of the reasons I write this post is because this has been misinterpreted quite a bit that this means that the security updates will be published until 2015. This is not true – only the anti-malware warnings will be issued. In other words, you’ll be given new buckets but the holes that leak won’t be patched anymore. And the effectiveness of antivirus or antispyware software on compromised system is at best limited. So in the long run, the upgrade to more recent operating system will be required. Of course, having malware on your system means all kinds of security issues, issues like compromising your private data and its integrity.
Will it be possible to continue using Windows XP – it depends – if you don’t need to connect it to Internet or any other network, then you can probably continue to use it. If however you need to connect online (even if it is from time to time) it means the system may be compromised. The time required to be online doesn’t need to be long so even short connection can be enough. My best advice is forget about patches and quick fixes and – upgrade.
