NVIDIA Streamer Service, NVIDIA Streamer Network Service and NVIDIA Streamer User Agent are three of the many processes running on Windows machines that are powered by recent NVIDIA video cards.
NVIDIA is notorious for pushing the limits when it comes to adding new services and processes to its drivers, and if you check your process listing on your Windows PC, you may very well see more than 10 different NVIDIA processes running on it.
You can verify that easily by using Ctrl-Shift-Esc to open the Windows Task Manager and scrolling down to processes starting with the letter N.
Some of these processes may not be needed at all, and chance is good that the NVIDIA Streamer related services fall into this category.
A recent check on a gaming machine revealed nine NVIDIA processes, and that is after using the custom installation option during installation of the graphics card driver on the system (not installing any 3D content).
So what is the NVIDIA Streamer Service being used for? It has been designed to stream games from the PC to NVIDIA Shield devices.
If you don't own a Shield, it is completely useless to you. What makes this a bad practice in my opinion is that the streaming services are running automatically regardless of whether a Shield device is owned or not.
There is no need to have these processes run on Windows machines all the time (or at all), and it makes sense to disable them as it may improve gaming performance on systems on top of that.
Disable the Nvidia Streamer Service
Disabling the service is thankfully pretty easy. Here is what you need to do:
Other NVIDIA services and their purpose
This takes care of three of the ten or so NVIDIA services running on your Windows machine. Depending on how you use your video card, you may be able to disable even more processes.
Many of these processes are related to the GeForce Experience. If you don't require any of those, then it may be best to uninstall GeForce Experience from Windows and to avoid installing it again during driver updates.
You may also find NVIDIA Capture Server Proxy when you are managing your startup items, and may disable it as well if you don't capture game content.
On Windows 7 and earlier, do the following:
If you are using Windows 8 or newer, do the following instead:
Please note that some of these services and processes may be reset when you install driver updates.
