If you have an nVidia GPU, you may not be aware that your driver is sending telemetry to nVidia.
This is the nVidia Telemetry service in Windows
We can disable it but every time the driver is updated, it will be re-enabled. So here's a nice trick to make sure that service can't start.
Right click the start button and run PowerShell as administrator, then copy this command and press enter
reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\NvTelemetryContainer.exe" /v Debugger /t REG_SZ /d "%windir%\System32\taskkill.exe" /f
Reboot and the telemetry is gone. The service is still there but it's unable to start.
This does not affect GeForce Experience, which has its own telemetry and you should not install it.
If you need a good recording software, check out OBS and configure it to use nvenc. This software is used by thousands of popular streamers and youtubers to record their games and it's really excellent.
