^^ I know about that ap and that app itself is a open source and free to use app but GAOTD periodically updates it's wrapper software to make such tools useless :
Here's the un-wrapper app download link - using this is legit I think :
GAOTD Setup Keeper | Free software downloads at SourceForge.net
But read the Description :
and this

so practically GAOTD just gives some users a a copy of a commercial app which is perfectly usable without any limitation for free but the catch is if one needs to reinstall it they either have to buy it or else stop using it.
Nw coming to the biggest question : what if it's a app ( provided for free by GAOTD ) which creates some files with proprietary extensions ? and the user has created some important files with it and he needs to re-install it ? or if the user got so much attached using a certain software ( provided for free by GAOTD ) - in both caase the user will but the app - so in a way GAOTD is just promoting commercial apps.
Now these types of scenarios must be covered by their EULA - but how many people properly read them ?
So I would say stop recommending GAOTD and recommend only pure free t use apps downloadble from either the author's website or a website recommended by the app makers.
