this will work
@echo off
cls
For /F "skip=1 tokens=1" %%A IN ('WMIC csproduct get vendor') DO echo %%A
pause

but it will not work with the set statement so i can use the if statement

In Win7 there is a trailing crlf that wipes the machine variable.

This should work in all OS

for /f "skip=1 delims=" %%a in ('WMIC csproduct get vendor') do if not defined machine set "machine=%%a"

And this will work to find dell in any machine vendor string

That seems to have worked. Thanks again everyone. Nice to simplify the batch. Here is final code and results.

REM @ECHO OFF
for /f "skip=1 tokens=1" %%a in ('WMIC csproduct get vendor') do if not defined machine set "machine=%%a"
ECHO Computer model: "%machine%"

IF %machine%==Dell (
GOTO :setup
) ELSE (
GOTO :end
)


:setup
echo success
pause > nul
GOTO :eof


:end
echo not yet
pause > nul
GOTO :eof
