Microsoft Windows XP Unsupported Installation Detection
Critical Nessus Plugin ID 73182
The remote operating system is no longer supported.
The remote host is running Microsoft Windows XP. Support for this operating system by Microsoft ended April 8th, 2014. Lack of support implies that no new security patches for the product will be released by the vendor. As a result, it is likely to contain security vulnerabilities. Furthermore, Microsoft is unlikely to investigate or acknowledge reports of vulnerabilities.
Upgrade to a version of Windows that is currently supported.
