What does the “end-of-support” mean?
PCI Data Security Standard states that all systems used by parties processing credit cards be patched and supported by their respective vendors. Clients not using a supported operating system are not PCI compliant and must update to a supported operating system immediately. To sum this up, you will not be in the scope of PCI compliance and could face fines.
