Those mentioned Wise software titles will create registry data (at least one CLSID key: HKEY_CLASSES_ROOT\CLSID\) regardless of how you use the software, and they'll create AppData if you click the button in it titled Assistance - not to pick on Wise software because I actually like it, just using it as an example.Īs for not remembering settings, some use. That's why I always track the first time usage of portable software using Total Uninstall.Īlso you can't really trust downloading the "portable" version of some software (lets use "portable" zipped Wise Disk Cleaner & Wise Uninstaller from the official homepage, and the versions Wise Disk Cleaner Portable & Wise Uninstaller Portable as examples) because the only thing "portable" about them is there's no traditional setup file (well the packaged versions sort of have a setup file, but it's just a pure SFX). Sure a 100% true portable won't do that, but some actually will create registry data, and some will create AppData, and some both. A portable app isn’t going to modify anything in the registry so there is less chance of things going wrong.
There is always the chance that a malicious file might be bundled in the EXE file but that comes down to the app itself coming from an unreliable source. * A portable app is unlikely to damage critical files on your system. These may include recent or frequently accessed files and directories among other things. * A portable app will not remember you personal preferences and settings. * A portable file will not modify the Windows registry in any way.
