What is one function you can perform with installed applications in Windows?

Managing installed applications is a vital function that can be performed within the Windows operating system. This includes tasks such as installing, updating, or uninstalling software. Administrators or users can access the Control Panel or Settings app to view all installed applications, allowing them to ensure that the necessary programs are present and up to date, as well as remove any that are no longer needed.

This management capability plays a crucial role in maintaining system performance and security. Regular updates to applications may provide enhanced features or patch vulnerabilities, making it essential for users to manage their software efficiently. By keeping software organized and current, users can avoid potential issues that could arise from outdated or unnecessary applications.

The other options listed—customizing the operating system kernel, changing the system architecture, and improving graphic rendering—are tasks that either require extensive technical knowledge, development expertise, or are outside the scope of typical user capabilities with installed applications. Therefore, they do not represent standard functions that can be performed directly by users through their installed applications.
