Windows 10: How to add custom folder icons as default?

hi, I am new to this forums, so pardon my mistakes...
I would like to know how to change the default plain folder icons to custom folder as default...
I was able to change lots of icons using customisergod from door2windows... but i got stuck with "folders which have content inside" and "folder and sub folders" icon... here's my work so far...



This is my computer screen, as u can see i was able to change those icons without any problems... but when i open a drive.. for ex



i have created folder back and folder front thinking that was what was needed for the folder with contents to change...



i tried to edit the icons in such a way as to replace the "folder back" and "folder front" with the custom ones.. but it wasnt working... i would be really happy if i could change the whole icon set to custom ones...

FYI: There are 5 icons for folders( Folder open, Folder Closed, Folder back, Folder front & "folder & subfolders"

Thanks in advance

:)

folder icons reverting to default when copied issue

Since the last Windows 10 update, I cannot copy anymore folders retaining their customized icon: the icon gets reset systematically to the default one. How can I reset this feature to as it was before (i.e. folders were copied with their customized icons)?

Since I cannot log on anymore, I cannot add these questions to my previous post:

1 - Has anyone figured out what caused the problem in the new release?

2- Does anyone know when it will be fixed?
