Article about NVIDIA processes.

According to this article the NVIDIA driver come with many useful processes:
Depending on how you use your video card, you may be able to disable even more processes.
NVIDIA Backend (NvBackend.exe) – This is part of Nvidia GeForce Experience.
NVIDIA Capture Server (nvspcaps64.exe) – Also part of GeForce Experience powering the ShadowPlay functionality. ShadowPlay enables you to record your games on your computer.
NVIDIA GeForce Experience Service (GfExperienceService.exe) – The main GeForce Experience service.
NVIDIA Network Service (NvNetworkService.exe) – Also installed with the GeForce Experience service. It prevents the update feature to work correctly which means that you won’t get new driver notifications or game setting update notifications anymore. If is however not required to run GeForce Experience, and you may disable it. You will get an error dialog box however when you run GeForce Experience after stopping the Network Service (you find it under Services: stop it there and change its startup type to disabled or manual).
NVIDIA User Experience Driver Component (nvxdsync.exe) – Virtually no information about the process is found on the Internet. The few resources found suggest it is used for 3D only.

Not useful for most users (my own opinion).

How to Flush DNS.

If you are running into a lot of “Page Not Found” errors and you know you’re connected to the internet, try flushing your DNS cache to have your computer request new information.
Open the command prompt and type ipconfig /flushdns and press key Enter.
Because most of computers that are connected to the internet automatically cache the hostname of the websites you have visited to make reloading the pages faster than if there was no cache.
If you used Linux OS then just use this: service restart network-manager and press key Enter. This will flush your fucking DNS.
