Windows XP Service Pack 4 Unofficial security enhancements:

Windows XP SP4 includes registry updates to enhance security. I want to thank Stefan Kanthak, a security expert who has kindly given me the necessary information. These security enhancements address issues not fixed by Microsoft updates.
This is an example of security vulnerabilities fixed by Stefan’s registry updates: //seclists.org/fulldisclosure/2013/Oct/151

While this patch is amazing and helpful at keeping your old machine alive or even allowing you to set up a stable XP Gaming rig, you should not really be using windows XP as a primary machine anymore, it has serious risks, even with this update.

Warnings

Microsoft has stopped providing Microsoft Security Essentials for download on Windows XP. If you already have Microsoft Security Essentials installed, you’ll continue to receive antimalware signature updates for a limited time. Please note that Microsoft Security Essentials  will have limited effectiveness on PCs that do not have the latest security updates. This means that PCs running Windows XP will not be secure and will still be at risk for infection.

What happens if I continue to use Windows XP?

If you continue to use Windows XP now that support has ended, your computer will still work but it might become more vulnerable to security risks and viruses. Internet Explorer 8 is also no longer supported, so if your Windows XP PC is connected to the Internet and you use Internet Explorer 8 to surf the web, you might be exposing your PC to additional threats. Also, as more software and hardware manufacturers continue to optimize for more recent versions of Windows, you can expect to encounter more apps and devices that do not work with Windows XP.
