The program supports /silent command and can be ran at any time.
But of course when using this in a automated setup of xp you would like to have the visual effects set for all user accounts that are created.

Heres how to do that with this program.

Now put the settings.ini and SetVisualEffects.exe in the folder $OEM$\$$\System32
on your setup cd. This will copy the files to the system32 dir of windows (which is where we want them to be and stay)

now in the folder $OEM$ you may or should have the cmdlines.txt file. You will need to put setstartup.reg in the $OEM$ folder with cmdlines.txt.

Now edit cmdlines.txt and add this to the second line (or any where as long as it is done before any accounts are created) "REGEDIT /S setstartup.reg" (make sure to have the " to.

Now you are all set.

Everytime you create a new account the program will run only once and set the visual effects.
