how to check windows version in batch file

[Dan B.]

Hello, can someone tell me the syntax I would use in a batch file (logon script) that checks the OS version? I want to use a logon script that only performs a function on XP machines as opposed to earlier versions. Thanks!

If your using VB Script then you can try this:

Code: [Select]

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
   & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")

Set colOperatingSystems = objWMIService.ExecQuery _
   ("Select * from Win32_OperatingSystem")

For Each objOperatingSystem in colOperatingSystems
   Wscript.Echo objOperatingSystem.Caption & " " & _
       objOperatingSystem.Version
Next
   
If you parse objOperatingSystem.Version you can extract the info you need.
     

OR with a .bat file

Code: [Select]

@echo off
ver > dummy.txt
for /f "tokens=1-4" %%i in (dummy.txt) do (if %%k=="XP" whatever
     )
del dummy.txt

You will have to make some adjustments depending on your situation.

Hope this helps.
