Which of the following is a standard way to close a window in Windows 10?

• A. Drag the window to the Recycle Bin
• B. Click the Close button in the upper-right corner of the window
• C. Use Task Manager to end the task
• D. Press the Power button to shut down

Answer: (B)

The standard way to close a window in Windows 10 is to click the Close button in the upper-right corner of the window. This is the normal, graceful method because it sends a close request to the application, allowing it to clean up resources and, if needed, prompt you to save any unsaved work before it exits. It’s the expected action you use every time you’re done with a window.

Dragging a window to the Recycle Bin isn’t a supported way to close apps; the Recycle Bin is for deleting files, not managing open windows. Using Task Manager to end the task can close a window, but that’s a forceful, last-resort action used when a program isn’t responding or won’t close normally. Pressing the Power button to shut down affects the entire computer, not just a single window, so it isn’t the right method for closing one window. As a common alt method, you can also press Alt+F4 to close the active window quickly.
