I don't think that you need to install Jenkins as a Windows service to execute a batch command as a build step. What might be an issue is that on Windows, commands such as dir are internal to the command interpreter (i.e. cmd.exe). In short, it means that in a Java program you cannot simply run the internal dir command using the java.lang.Runtime.exec("dir") method because there is no such a program as dir.exe (on your PATH). What you should do is execute the command interpreter itself and specify the internal command as a parameter, i.e. java.lang.Runtime.exec("cmd /C dir"). Having that said and being aware that Jenkins is a Java application, it's better to use cmd /C dir instead of just typing dir in Jenkins' job configuration. Internally, Jenkins might use some 3rd pary libraries for executing external processes, such as Apache Commons Exec (see http://commons.apache.org/exec/), which hide the details between internal command(s) and "normal" commands, but from my experience it's not the case for all releases - especially the old ones.

Answer to this question: Actually i haven't installed Windows as a service in Jenkins. So for this we need to go to "manage Jenkins" and then click on "windows as a service".I.e Installing Jenkins as a windows service.
