janecraft - This topic was originally about the 'full version'. That's one of the problems with tag-on posting.
As for the USB versions, apparently some errors were made in packaging and descriptions. I have no part in that process, I'm just a 'volunteer question answerer'.
To get the Control Panel, just download the zip or .7z of the full version and extract the archive. I think the only file you need is xampp-control.exe. Copy it into the root of your XAMPP installation
