The end of Windows XP

Microsoft is ending support for Windows XP SP3 in 2014!
In 2002 Microsoft introduced its Support Lifecycle policy, and as per this policy, Microsoft Business and Developer products receive a minimum of 10 years of support, and this means that Windows XP SP3 will go out of support on April 8, 2014. Although the headline is for XP SP3 (Service Patch 3), this is simple the end for for Windows XP, as SP3 is the last recognised release of XP.
Why is this important?

After this date, Microsoft will no longer provide security updates, non-security hotfixes, free or paid assisted support options or online technical content updates for Windows XP. Running XP after their end the support date may expose your company to potential security risks, as any vulnerabilities found in windows core code will be updated for current operating systems. You may also face compliance risks resulting from an officially recognised control failure by an internal or external audit body, leading to suspension of certifications, and/or public notification of the organisation’s inability to maintain its systems and customer information.
