You need an empty argument to launch by double click. Make a shortcut with target as shown below. C:\gnu\emacs-25.2\bin\emacsclientw.exe "" --alternate-editor C:\gnu\emacs-25.2\bin\runemacs.exe When create file associations, you may want add --create-frame to behave like other Windows application. For example, ftype txtfile=emacsclientw -cna runemacs "%1" instead of ftype txtfile=emacsclientw -na runemacs "%1" as shown in EmacsWiki.
