Sets or retrieves the name of the current window object, which is used to identify the window.
With the name property, the name of a window can be modified, after the window has been created. It is also possible to specify the initial name of a newly created window.
When a window is opened by an anchor, then the target property specifies the initial name of the created window. For details, see Example 1 or the page for the target property.
When a window belongs to a frame or iframe element, then the name property sets the initial name of the contained window. See Example 2 for details.
Finally, if a window is created dynamically by the open method, then the second parameter of the method specifies the initial name of the created window. See Example 3 for details.
The name of windows can be used to identify them. When a new window needs to be opened with a specified name and a window opened by the current document already exists with the same name, then the browser uses the existing window instead of creating a new one.

4. Scroll down to the "Miscellaneous" section, and choose "Enable" for "Allow script-initiated windows without size or position constraint"
5. Restart Internet Explorer for settings to take effect.
After I do research on this, I have found out the following:
The window name field in the "Open URL in Window" configuration doesn't become the winddow name.
The Window Name is a way to name a popup window so that you can either replace the contents in the same popup window, additional window.open calls using the same window name, or creating a new popup window by using a different window name.
Hence this field cannot be used to set the pop up window title.
The window title is dictated by the HTML put into the popup window within the <title> attrbute. Example:
