How to save Excel Workbook to Desktop regardless of user?

I have an Excel Workbook that on Form Button click I need to save a copy of the workbook to the user's Desktop.

Originally everything was going to be on a shared Network folder, but now I have about 6 different users that when they click the button, I need to save the workbook to their individual Desktops.

Is their a way (coding-wise) to save to the machine Desktop without having to specify individual users (which would require me to maintain 6 different Workbook files)?
