Batch exclude windows, with ver command

Question

I want a code who jump to :jumpto if the windows is older than windows 8 (win 7 and older)

IF "windows is older than Windows 8" 6.2.9200.16384 goto jumpto'

I cannot formulate the correct code. Anyone who can help me out please?

I guess if i can use ver and calculate if numbers are lower than 6.2?

Answer 1

This should work:

@ECHO OFF
FOR /F "tokens=*" %%a IN ('ver') DO (
    SET ver=%%a
)
SET v1=%ver:~27,1%
SET v2=%ver:~29,1%
IF %v1% LSS 6 GOTO JUMPTO
IF %v2% LSS 2 GOTO JUMPTO
ECHO doing something
PAUSE
GOTO:EOF
:JUMPTO
ECHO Windows version too old!
PAUSE
