SP1

Service Pack 1 (SP1) is an update released by software companies, such as Microsoft, that improves the stability, security, and performance of a program or operating system. Instead of releasing a whole new version, SP1 bundles important fixes and enhancements into one package. Installing SP1 helps ensure your software runs smoothly, protects against vulnerabilities, and may add useful features or improvements based on user feedback. Think of it as a comprehensive upgrade that keeps your system current and reliable without needing a complete reinstall.
