Reboot Pending Prompt - Detection

Overview

This script serves as the detection logic for the Reboot Pending Prompt solution. Its primary function is to intelligently decide whether a reboot prompt should be displayed to the user.

It performs checks in three key areas:

1. Operational Safety: Before evaluating necessity, the script checks if the Reboot Pending prompt - Autofix is currently active (specifically checking for the scheduled task it manages). If a prompt cycle is already in progress, this script exits immediately to prevent conflicting or duplicate actions.
2. Necessity: It determines if a reboot is actually required by checking Windows Registry keys (for pending updates), comparing system uptime against a configured threshold, or checking for a manual administrator override.
3. Timing & Convenience: If a reboot is needed, the script then validates if the current moment is appropriate for a prompt. It checks constraints such as "Quiet Hours" (suppress windows), weekend exclusions, user presence (logged in vs. lock screen), and ensures the user isn't prompted too frequently.

If the script determines a reboot is needed, the timing is valid, and no conflicting prompts are active, it returns an exit code that triggers the remediation script.

Sample Run

Note: This script is specifically engineered to operate as the detection condition within the Reboot Pending Prompt - Windows Workstation policy. Manual execution is not recommended, as the script's output is intended to trigger automated remediation actions rather than provide direct feedback.
