Weird microphone & circle icon embedded in editor windows.

At first, i am updating to unity 5.4 and nothing weird is going on. There was some warning from plugins that i can solve. After some day, when i open unity, suddenly there was some weird item embedded in all unity editor windows. Please take a look to the image i attached below. There are two icon in the screen shot, a microphone and circle with a line. I draw red line to highlight the icons.

The weird thing is, my team member which use the same unity version and same code base don't have those icon. I Try to uninstall unity, remove unity application data, and remove unity in windows registry then reinstall unity but the icon persist. Other projects in my machines also have those microphones and circle icons.

At this moment, there is no error occurs, but the icon is so annoying. Is there any way to remove it? And what is this icon indicated? There is no log that that related with that icon, but i attach editor log for reference. That icon is embedded into default unity editor windows (inspector, game, scene, etc), so i think it is related to unity internal.

I am using windows 7 and Unity 5.4.0f3. Any help is highly appreciated!

 

After some googling, the icon is causes by Nvidia Shadow Play. I disable the shadow play in windows startup and the microphone and circle icon is disappear from unity.
