You can add your Tcl/Tk programs to the Windows start menu. The command is the complete name of the wish.exe program and the name of the script. The trick is that the name of wish.exe has a space in it in the default configuration, so you must use quotes. Your start command will look something like this:
"c:\Program Files\TCL82\wish.exe" "c:\My Files\script.tcl"
This starts c:\My Files\script.tcl as a stand alone Tcl/Tk program.
