What permissions to grant to WCF Service hosted on IIS for desktop screen access?

I created WCF service and then hosted on IIS on my machine. Service is accessible through browser, it means hosted correctly. In this service, i am using screen video capturing implementation. The problem I am facing is that, when i run the service, video file created and recording started. After recording stop, when i open, the recorded video file has black screen recording. I found on the internet that windows by default do not allow browser interaction with desktop. But i do not found any best solution for my scenario. What i must allow permissions for accessing desktop from my WCF service hosted in IIS on my machine.

I have been set NoInteractiveService to 0 from registry, but not working.
