title: batch CMD for different versions of windows compatibility
body: <p>Good Evening</p>
  
  <p>Ive been searching for some hours looking for a way to test a batch file locally that will need to run on several versions of windows, (NT,2000,XP,7,10) </p>
  
  <p>Ive been searching for CMD.exe versions from each to no avail. Am i looking in the wrong place? or is this not the way forward</p>
  
  <p>Thanks</p>
  
  <p>On a side note, I found interesting Windows 10 CMD holds %OS% variable as Windows_NT ... bizarre, assuming an old feature that was forgotten about?</p>
