How do I know if my PC is enrolled in Windows Insider Preview?

[Windows Central Question]

I registered for windows insider preview but I never installed the preview builds. My pc is now running with windows 10 installed. I'm just curious if my PC has the build for insiders. I'm a little bit worried about my PC sending telemetry data to Microsoft.

When you download Insider Preview, you will agree that microsoft can take some data on your pc. this is because insider preview is for beta testing. They need to fix glitches or something like that. They won't use it for bad things..

To check if you are in insider preview,

Go to Settings > Update & Security > Windows Update > Advanced Settings.
