Well, two weeks I go I gave it a go with the current build, and I did something wrong. I didn't really care so I decided on working with RunOnceEx (which was also a whole new concept to me ). Now, with way more experience, I tried this XPlode4 and it rocks! It looks so much more professional than any other solution. Thanks Wraith, u rule. Two questions tho: - This one's probably answered yet, But I'm gonna ask it anyway. Is every program able to install in the T-12 stage? It sound totally not logical to install stuff when Windows isn't even loaded yet. - Second, these usergroups, do they only work on XP Pro or with a network? Is it basically using "net group"? Not that I need them, but I'm curious. And tnx again for this great tool, keep up the good work.
