It's been brought to our attention that nVIDIA now has telemetry included with its drivers 
most likely if you installed 
GeForce Experience with the drivers. I'm getting conflicting reports whether it's specific
 to GeForce Experience or not. Regardless, it also continues the bloat 
with nVIDIA Wireless Controller and ShadowPlay services, something many 
don't need.
First, let's go over what these are.
[*] Telemetry is essentially considered spying by many as it is a way to send data back 
and forth. It's nowhere near that simple, but we'd like to know what 
it's doing in our video drivers when it's never been needed before.
[*] nVIDIA Wireless Controller requires you have, you guessed it, a nVIDIA Wireless Controller.
 ShadowPlay is a way to capture and record gameplay.
Type nvidia in the filter box.
You will find Telemetry in the Task Scheduler section and the nVIDIA Wireless Controller, and 
ShadowPlay services further down under the registry entries. 
Uncheck what you don't want, close and reboot. If you get an error, close the 
program and right click on Autoruns.exe or Autoruns64.exe and "Run as 
Administrator."
