After April 8, 2014, technical assistance for Windows XP will no longer be available, including automatic updates that help protect your PC. Microsoft will also stop providing Microsoft Security Essentials for download on Windows XP on this date. (If you already have Microsoft Security Essentials installed, you will continue to receive antimalware signature updates for a limited time, but this does not mean that your PC will be secure because Microsoft will no longer be providing security updates to help protect your PC.)
If you continue to use Windows XP after support ends, your computer will still work but it might become more vulnerable to security risks and viruses. Also, as more software and hardware manufacturers continue to optimize for more recent versions of Windows, you can expect to encounter greater numbers of apps and devices that do not work with Windows XP.
To help customers on Windows XP prepare to move to a new PC, Microsoft announced a free transfer tool. They partnered with Laplink to provide Windows XP users with a free data migration tool called PCmover Express for Windows XP which copies your files and settings from your Windows XP PC to a new device running Windows 7, Windows 8 or Windows 8.1. This tool will copy your files, music, videos, email and user profiles and settings from your old PC to your new device, transferring across your home or work network, and even enables Windows XP users to customize exactly what they want to bring over to their new device. The free data transfer will NOT migrate your apps. Learn more and download the free version of Laplink PCmover Express for Windows XP here.
For Windows XP users wanting to transfer applications from their old computer, Laplink is also making available its software that migrates apps, files and settings called PCmover Professional at a special price – see here for details.
