  @ECHO OFF

  :: Win9x checks ::::::::::::

  VER |find /i "Windows 95" >NUL
  IF NOT ERRORLEVEL 1 GOTO W9598ME

  VER |find /i "Windows 98" >NUL
  IF NOT ERRORLEVEL 1 GOTO W9598ME

  VER |find /i "Windows Millennium" >NUL
  IF NOT ERRORLEVEL 1 GOTO W9598ME

  :: NT/XP checks ::::::::::::

  VER | find "XP" > nul
  IF %errorlevel% EQU 0 GOTO s_win_XP

  VER | find "2000" > nul
  IF %errorlevel% EQU 0 GOTO s_win_2000

  VER | find "NT" > nul
  IF %errorlevel% EQU 0 GOTO s_win_NT

  ECHO Unknown OS !
  GOTO :EOF

  :: Win9x commands ::::::::::::

  :W9598ME
  ECHO Win9x commands go here
  GOTO :EOF

  :W98
  ECHO Win98 commands go here
  GOTO :EOF

  :: NT/XP commands ::::::::::::

  :s_win_XP
  ECHO XP commands go here
  goto :eof

  :s_win_2000
  ECHO WIN2K commands go here
  goto :eof

  :s_win_NT
  ECHO NT4 commands go here
  goto :eof

  :EOF (End-of-file)

Notice that the VER command reports the version of CMD.exe, so if for example you run the Win XP version of CMD under NT 4 then the VER command will return:

Microsoft Windows XP [Version 4.0.1381]
