It’s all about security.
After April 8, 2014, there will be no new security updates, non-security hotfixes, free or paid assisted support options or online technical content updates for Windows XP.
If you lay awake at night worrying about IT security, that should make your heart flutter a bit.
Running Windows XP SP3 after its end of support date may expose your company to potential security and compliance risks. New vulnerabilities will not be addressed by security updates, making it easier for attackers to successfully compromise Windows XP-based systems. Anti-malware software and other security mitigations are severely disadvantaged and will become increasingly unable to protect the Windows XP platform.
According to Microsoft blogger Tim Rains, data collected after support for Windows XP Service Pack 2 ended in 2010 shows what happens to malware infection rates once a platform goes out of support. Although this platform benefited from numerous security enhancements when it was released, he says that today it has a much higher malware infection rate than Windows XP SP3 or any of the newer Windows operating systems.
Rains says that much of the elevated infection rate on Windows XP can be attributed to the fact that some of the key built-in security features included with more recent versions of Windows are not present in Windows XP. Windows XP, designed in a different era, simply can’t mitigate threats as effectively as newer operating systems, like Windows 7 and Windows 8, he says.
“Security mitigations built into Windows XP are no longer sufficient to blunt many of the modern day attacks we currently see,” says Rains.
You might also find it difficult to receive support from independent software vendors and hardware manufacturers.
The bottom line is, the deadline is looming, so get your own post-XP plan in order.
