My question is in regard to the checkmarks/checkboxes of context menus. In my opinion they look unappealing and I'd like to be able to replace the checked/unchecked states graphics if possible. It can be seen in Ribbon context menus but in other context menus as well.
I'm linking a video to better illustrate what I am talking about: https://imgur.com/NWAb5St
Could you please show me how to replace the checked/unchecked states graphics?
