Comprehensive and Detailed Explanation From Exact Extract:
Operating systems periodically reach a status known as "end of life" (EOL), at which point the developer (e.g., Microsoft, Apple) ceases to provide security updates, patches, or technical support. When this happens, the OS becomes vulnerable and non-compliant with security best practices, which is why organizations typically receive advance notifications from vendors or support teams.
A. Manufacturer support expiration only applies to hardware, not OS patching.
C. Security software may be upgraded or removed, but that does not affect patching the OS itself.
D. The release of a new version doesn’t automatically stop updates for the current version.
