I need to find the flavor of Windows that is running using a batch file that will run on anything from Windows NT to Windows 7. I'm using a method based on this page with some minor changes.

Systeminfo gives the flavor of Windows that is running. Is there any authoritative list of names that can be returned? If so where would I find the list?

My intention is to do something like:

 winVer=Unknown

 rem NT doesn't have systeminfo
 ver | find "Windows NT" > nul
 if %errorlevel%==0 set winVer=WinNT

 for /f "delims=: tokens=2" %%v in ('sysinfo ^| find "OS Name"') do (
  set verStr=%%v
 )
 echo %verStr% | find "Windows XP" > nul
 if %errorlevel%==0 set winVer=WinXP
 echo %verStr% | find "Windows Vista" > nul
 if %errorlevel%==0 set winVer=WinVista
 ... etc

Thanks
