The first thing you need to know: Support for Windows XP ends on April 8, 2014. You can get solutions to your Windows XP security issues now, but not for too much longer. If you’re still using Windows XP, you’re missing out on all kinds of security, productivity, and performance enhancements available in Windows 7 and in Windows 8.
If your computer is running Windows XP, you should take action. After April 8, 2014, Microsoft will no longer provide new security updates, non-security hotfixes, free or paid assisted support options, or online technical content updates for Windows XP. Learn more about the product lifecycle.
To continue to get support, including security updates and updates to help your computer be more reliable, consider an upgrade sooner rather than later.
If you choose to continue using an unsupported version of Windows XP, Windows will continue to start and run. However, you won’t receive any software updates, including security updates that can help protect your computer. Think of it like an older car with non-working airbags: The car still works, but it’s not the safest ride in town.
