Microsoft ended support for Windows XP on April 8. Information technology has worked with S&T departments to identify and phase out more than 3,000 XP systems over the past three years. Now that Microsoft has officially ended support, once a security exploit for Windows XP is detected by IT Security, access to the campus network may be prohibited for any Windows XP system without further notice. The campus community is encouraged to upgrade any personally owned XP systems to avoid security and network access issues.
