# Disable Telemetry
# Note: This tweak also disables the possibility to join Windows Insider Program, as it requires Telemetry data.
# Windows Update control panel may show message "Your device is at risk because it's out of date and missing important security and quality updates. Let's get you back on track so Windows can run more securely. Select this button to get going".
# In such case, enable telemetry, run Windows update and then disable telemetry again.
