how to add emblem to windows file icon?

Question

I want to know how to add some sort of emblem or badge to a specific file. Just like drop box does to a specific file when it is doing a sync.

I found that the guys from drop box are able to do that on linux by using libnautilus package. But I need to do so on windows and haven't been able to find an answer.

Will the solution change from one windows version to other?

best regards
