You might try just using the shutdown command in windows to simplify $APP_NAME: 
Usage: shutdown [-i | -l | -s | -r | -a] [-f] [-m \\computername] [-t 
+xx] [-c "comment"] [-d up:xx:yy]

        No args                 Display this message (same as -?)
        -i                      Display GUI interface, must be the fir
+st option
        -l                      Log off (cannot be used with -m option
+)
        -s                      Shutdown the computer
        -r                      Shutdown and restart the computer
        -a                      Abort a system shutdown
        -m \\computername       Remote computer to shutdown/restart/ab
+ort
        -t xx                   Set timeout for shutdown to xx seconds
        -c "comment"            Shutdown comment (maximum of 127 chara
+cters)
        -f                      Forces running applications to close w
+ithout war
ning
        -d [u][p]:xx:yy         The reason code for the shutdown
                                u is the user code
                                p is a planned shutdown code
                                xx is the major reason code (positive 
+integer less than 256)
                                yy is the minor reason code (positive 
+integer less than 65536)
