I doubt anyone else contributing to this thread was unfamiliar with workbook pinning. You may have thought you were explaining the pinning function, but what you described in your first post is something entirely different - what you described is what anyone else might think of as being the 'keep on top' function that you can use with programs like the Windows Task Manager. You can't do that with Excel.
