Installation and configuration changes
After starting, the script offers selection of Windows Insider Program channels. To make a selection, press a letter coresponding to option you choose and press ENTER.

If the machine was not enrolled to the Insider Program, you will get prompted to restart your machine to enable Microsoft Flight Signing which is required by Windows Insider Program.

Notice: Windows Insider Program requires telemetry to be set to Full. After enrolling your machine to the Windows Insider Program please make sure that your diagnostic data collection settings are set to Full. Some Insider Preview builds may not get offered in Windows Update if you do not have correct telemetry settings.

You can verify or modify your telemetry settings as follows:

Windows 11: Settings > Privacy and Security > Diagnostics & feedback

Windows 10: Settings > Privacy > Diagnostics & Feedback

Restoring Windows Insider Program to default options
To restore Windows Insider Program to default settings simply choose Stop receiving Insider Preview builds in OfflineInsiderEnroll Script. You will get prompted to reboot, because this option will disable Microsoft Flight Signing.
