Why not to add Unchecky to Portableapps? If you don't know what Unchecky is, there is a copypasta from their website https://unchecky.com/
"Tired of unchecking unrelated offers while installing software?
Have you ever felt, while installing software, that the installer tries to push additional unwanted programs at all cost? Ever missed a checkbox, and spent hours afterwards removing adware? Ever opened your browser after an installation, only to find out that you have a new homepage, a new search engine, or even a new browser?
Unchecky aims to keep potentially unwanted programs out of your computer.
Keeps your checkboxes clear.
Unchecky automatically unchecks unrelated offers, both saving you mouse clicks and making it less likely to miss a checkbox of an unwanted offer.
Installers often try to sneak additional programs as a natural part of the installation. Unchecky warns you when you try to accept a potentially unwanted offer, which makes it less likely to be accepted accidentally.
Install and forget. Unchecky automatically updates whenever a new version is available, so you don't have to worry about running the latest version."
