In one embodiment, a presenter device may determine displayed windows of applications, and may provide individual window sharing selectability (e.g., shared or unshared), as well as entire application sharing selectability (shared, unshared, or neither). In particular, the entire application sharing selectability takes priority over individual window sharing selections (i.e., all windows of shared applications are shared and all windows of unshared applications are unshared). Based on individual window sharing selections and entire application sharing selections, a set of presenter device windows that are to be shared with the attendee devices may be determined, as well as a set of unshared windows that are not to be shared with the attendee devices, and the presenter device may share the set of shared windows with the attendee devices, without sharing the set of unshared windows.
