my problem is that i can't find what option i need use

Open a folder,  set it how you want it to be, then go in folder options through the menu of that opened folder and click on the button that says something like: "View all folders like this one".

If this does not work, and it probably doesn't, then you can change, in the registry, the default action when double clicking on a folder from Open to Explore.

Doing this however will likely not let you browse in place anymore but instead will open a new window for each folder you open within a folder.

i'm just did now but isn't saved

if i run it on start menu, the folders three is showed

If you want a folder to open like when you run explorer, showing the tree view, then, as I've said above, you need to change the default action for opening folders from Open to Explore.

theres no patch or a regist file for change it?

Go in folder options, filetypes tab, find folders entry, select it and click on the "Advanced" button. Set explore as default action.
