Software developers don't call your software "portable" if it's not portable. It's pretty black and white. If your software leaves shit behind  IT IS NOT PORTABLE!

Examples of "portable" software that is not in fact portable:

CherryTree (leaves shit in AppData\Roaming\cherrytree) (http://www.giuspen.com/cherrytree/)

Ultra Recall (http://www.kinook.com/UltraRecall/)

VMware ThinApp devs...

VMware ThinApp developers, if your "portable" software leaves shit in "AppData" folder, IT IS NOT PORTABLE!
