Which of the following is the primary method for uninstalling programs in Windows 10/11?

• a) File Explorer is used for managing files and folders, not for uninstalling programs.
• b) In Windows 10 and 11, programs are uninstalled by navigating to Settings, then selecting Apps, and then Apps & features. This allows users to manually uninstall programs.
• c) Control + Alt + Delete opens a security options screen, which includes access to Task Manager, but not directly to program uninstallation.
• d) Task Manager is used to monitor and manage running processes, performance, and startup applications, but it does not provide a direct way to uninstall software.

The "Settings → Apps" path is the standard method for manually uninstalling programs in current Windows operating systems.

The final answer is $\boxed{\text{b. Settings} \to \text{Apps}}$.
