For _WindowsLookAndFeel_ the `InteriorBackground` color is not been used when checkbox paint happens. In _WindowsLookAndFeel_ the CheckBox check/uncheck is drawn using `ImageCache` which is totally independent of `InteriorBackground` color in which the user expects it to be.

Spent some time to check where all we are using these properties.
I see that we use "CheckBox.background" for CheckBoxIcon when it is pressed at https://github.com/openjdk/jdk/blob/master/src/java.desktop/windows/classes/com/sun/java/swing/plaf/windows/WindowsIconFactory.java#L389

Can you check why we use "CheckBox.background" instead of "CheckBox.interiorBackground" in WindowsIconFactory and what is its behaviour in Windows 11?

Do we return any color other than the default FFFFFF/null?
What is the use of "win.frame.backgroundColor" property when we always return table.get("window")?
