Windows 7 PE

Howdy Guys!

I think this topic goes here, I'm not entirely sure haha.

So using Winbuilder, I made a Windows 7 PE. I'm using this so I can do repairs and so on for viruses, driver troubles, etc like its meant for.

I understand how to install portable apps onto the PE, but I'm trying to figure out how to install full apps like Avast! and so on that require registry edits and such. Does anyone know how to do this?

Just asking, worth a shot sicne I can't find anything on Google or the Winbuilder support forums.

Thanks!
