I know this is a very old topic but i would like to answer it regardless:

you can't edit msconfig directly, that is to say that msconfig itself isn't the settings of the computer. What i mean is that msconfig is just a nice graphic user interface that helps you edit the registry without having to open regedit. Essentially you would need to add registry keys or delete ones that are there using vb 6.0, I know registry editing is possible in vb 6.0, but is a pain, however it's very easy in vbe 2008 or 2010, so use one of those.

I'm probably going to get flamed for posting on a topic over 4 years old, but oh well lol.
