How can you resize the program window?​

Resize a window by dragging the edges or corner of the window. Hold down Shift while resizing to snap the window to the edges of the screen and other windows. Move or resize a window using only the keyboard. Press Alt + F7 to move a window or Alt + F8 to resize.

If you are running Microsoft Windows 7, Windows 8, or Windows 10, you can use Windows key keyboard shortcuts to resize and arrange windows on your computer. For example, pressing the Windows key and the left arrow key resizes it to fit only the left half of the screen.
