AI Overview
Many modern ATMs have migrated away from Windows XP, though a small percentage of legacy and independent machines still run older operating systems.
Why Windows XP Was Common
• Ease of Development: Banks favored Windows XP for its graphical user interface and standard integration tools (such as CEN/XFS for hardware like card readers and printers).
• Long Lifespans: Upgrading ATM software often requires expensive hardware replacements and custom code rewrites, causing financial institutions to delay transitions.
Current Status
• Shift to Newer Systems: Most modern ATMs now run on newer platforms like Windows 7 or later operating systems.
• Remaining Legacy Units: A small fraction of older or independent ATM networks continue to operate on legacy software, though standard security and custom extended support agreements have largely phased out unpatched Windows XP deployment.
