To restart a service via a batch file, open a blank notepad file.

type net stop “servicename”
type net start “servicename”

For example, you would stop the printer spooler service by typing:

net stop “Print Spooler”
net start “Print Spooler”

Once done, save the file with a .bat extension. Example restart.bat

Note: You may need to re enter the speech marks if you were to copy the above command into a notepad.
