You can remove the need to update model entirely from your script if you have your folder names match your model names.
You have, essentially:
echo Model Number is %model%
if "%model%"=="Latitude E6400" goto E6400
if "%model%"=="Latitude E6410" goto E6410
if "%model%"=="Latitude E6420" goto E6420
if "%model%"=="Satellite Pro a120" goto A120
:E6400
echo Latitude E6400
"J:\Task Handler\rdeploy\firm.exe" -recurse copy K:\WindowsXP\E6400 prod:\
goto Exit
:E6410
echo Latitude E6410
"J:\Task Handler\rdeploy\firm.exe" -recurse copy K:\WindowsXP\E6410 prod:\
goto Exit
:E6420
echo Latitude E6420
"J:\Task Handler\rdeploy\firm.exe" -recurse copy K:\WindowsXP\E6420 prod:\
goto Exit
:A120
echo Satellite Pro A120
"J:\Task Handler\rdeploy\firm.exe" -recurse copy K:\WindowsXP\A120 prod:\
goto Exit
When you could easily use a variable:
fso.CopyFolder "W:\<driver root path>\" & strName & "", "M:\Drivers"
Now all you need to do is name your folders after the model name pulled from the WMI query (Satellite Pro A120, Latitude E6420) rather than something arbitrary that gets entered by a highly-paid technician into a text file (A120, E6420), which is time-consuming and prone to error.
