What type of updates does a Service Pack primarily provide?

A Service Pack primarily provides security and system enhancements. Service Packs are comprehensive updates for software, particularly operating systems, that typically bundle various updates into one package. These updates often include critical security patches, bug fixes, and performance improvements, ensuring the software operates reliably and securely.

While attractive features or user-interface improvements may occasionally be included in a Service Pack, the primary focus is on stability and security enhancements. These updates help to mitigate potential vulnerabilities and enhance the overall performance of the system, contributing to a more robust and secure user experience.

In contrast, new features are usually reserved for major releases or upgrades, while experimental updates are often found in beta software rather than stable releases like Service Packs. User-interface improvements might be included but are not the main objective of Service Pack updates. Thus, the emphasis on security and system enhancements makes this the correct answer.
