Inherit/push/replace ownership on files/folders

I use SetACL to change most of the permissions on ascript i am writing but from what i have found it will not change the owner on a large scale. Only on a small scall like one folder, but not anything in that folder. Or one file all by its self. I am looking for a tool that will allow me to change the owner on a folder and have i change all the files in that folder to have the same owner.

Also if anyone knows of a tool that would allow me to change the permissions on the root of C: and the power users folder I could use info on that as well. I cannot get SetACL to do those things.
