Microsoft OneDrive and OneDrive for Business register multiple icon overlay handlers to indicate the synchronization and share states of the files that are managed by those applications. Because OneDrive is installed by default on Windows 10 systems, the number of icon overlay handlers that other applications can register before the problem that's described in the "Symptoms" section occurs is effectively reduced. OneDrive currently registers five icon overlay handlers, and there are four system icon overlays. This leaves just six slots in the system image list for use by other icon overlay handlers.
