batch file registry comparison

Hey guys, first time posting here so hopefully this will help me greatly...

I am trying to write a batch file that will call up "hklm\software\microsoft\windows nt\currentversion\csdversion" and determine if Service Pack 2 is installed. If SP2 isn't installed, have it install it for me. Any help would be awesome thank you.

I found the answer if anyone wants to know.....


@ECHO OFF

FOR /F "tokens=2* delims= " %%A IN ('REG QUERY "HKLM\software\Microsoft\windows nt\currentversion" /v csdversion') DO SET spver=%%B
ECHO Service Pack Version = %spver%

if not "%spver%" == "Service Pack 2" (
echo install service pack 2
rem **insert path and sp2 location here**
)

if "%spver%" == "Service Pack 2" (
echo Service Pack 2 is installed
)

pause

 

Nope!

Code:

Service Pack Version = 2, v.2149
install service pack 2
Press any key to continue . . . 

I have SP2 installed. You need to get the first charachter of the %spver% variable to get the SP number, after the comma is the build number
