Question

How can I change the icons of window button? Is it possible?

Answer 1

This will involve changing your theme. But what you can do is create your own theme.

Its not as hard as it seems:

1. copy a base theme
2. replace the images currently used with the ones you want to use
3. choose the theme you just created in appearance settings.

Answer 2

By changing your Themes (System Settings > Appearance > Theme drop-down options) you change the icons you see in Nautilus and other programs.
