TCExplorer includes OTFExplorer in it already so you do not have to download OTFExplorer separately. It is one exe file that creates a single ini file. I checked the registry and there is nothing in HKCU\Software nor HKLM\Software, but others might want to check more thoroughly.TCExplorer is a portable software to import, export, delete, and rename files in TrueCrypt containers without needing admin rights. This is basically a GUI for the wonderful OTFExplorer by tateu.
