batch file - Keep X instances of Y running at all time, windows -

How can I make sure with the batch script that I always run an ex example of cmd.exe for example?

I have searched and found that it gives me NBR X lines if X is running.

  tasklist / FI "IMAGENAME eq exe.exe" 2 & Gt; NUL |   
 And then  START XXX X  has stopped running any one, then Find / Find / I / n "exe.exe"?  
  
 
 
 how about  
  set PROG = exe.exe set COUNT = 0 set = 5 want / f "skip = 1" %% i IN (get wmic process name where name = "% PROG%") (if / i %% i% PROG% set / one COUNT + = 1 is the same) Exclamation count: %%% %% (% 1%,% WANT%) %% of WANT% gtr %% of% /%>% /% / html>
