 Closing running applications on Windows can be done in several ways. Here are a few methods:

• Using the Taskbar:
  
  • Locate the application icon on the taskbar (usually at the bottom of the screen).
  • Right-click on the application icon.
  • Choose Close window or Close all windows from the context menu.
• Using Alt + F4:
  
  • Bring the application window into focus (click on it).
  • Press Alt + F4 on your keyboard. This keyboard shortcut is a universal way to close the active window.
• Using Task Manager:
  
  • Press Ctrl + Shift + Esc to open Task Manager.

• Using the System Tray:
  
  • Some applications may run in the system tray (bottom-right corner of the screen near the clock). Right-click on the application icon in the system tray and choose the option to close or exit.

Remember that closing an application might not always exit the program completely, as some applications run background processes. For a more forceful closure, you can use Task Manager as mentioned in method 3.

  Closing running applications on a Mac can be done using several methods. Here are some ways:

• Using the Dock:

Choose the method that best suits your preference or the specific situation. Using the standard quitting methods (Quit from Dock or Menu Bar) is the preferred way to close applications, as it allows the application to perform necessary cleanup tasks before exiting. If an application is unresponsive, you can resort to Force Quit or Activity Monitor to forcefully close it.
