Best Practices for Windows XP
Windows XP systems should be upgraded to another OS as soon as possible
Microsoft ended support for Windows XP on April 8, 2014. It will receive no further security updates. Due to its large install base, Windows XP is expected to remain a popular target for attackers after security updates cease.
We strongly recommend that any computers running Windows XP be decommissioned or upgraded to a different operating system as soon as possible.
