I have found on technet an interesting script for taking ownership of the folders here, many thanks to Boe Prox for this amazing function
In my case I had to use the script as the company I work for decided to give “Full control” to the users on several folders and that induced a problem wich users are owners of several shared folders and can modify permissions as they please and as Admins we do not want that ;
https://gallery.technet.microsoft.com/scriptcenter/Set-Owner-ff4db177
To simply make it your own you will modify the param to change it to your security group as for example in this case “Domain Admins”;
Also I have put how to perform the usage and also copied the whole script
