If it's a windows service (if not, you can make it into one, but that's beyond the scope of this reply), you can do a batch file or a perl script (as suggested above), but the key is to use net {start|stop} so you don't have to deal with the pids yourself (which of course is possible):

REM batch file method:
net start my_service
perl -e "sleep 10"
net stop my_service

# perl method:
system("net start my_service");
sleep 10;
system("net stop my_service");
