Reboot Pending Prompt - Autofix

Overview

This script acts as the remediation (Autofix) component of the "Reboot Pending Prompt" solution. It is triggered automatically when the Detection script determines that a reboot is necessary and conditions are right to interrupt the user.

Since RMM scripts run in the background (Session 0) and cannot normally show windows to the user, this script utilizes a temporary Scheduled Task to bypass this limitation. It launches a branded GUI utility (Prompter.exe) inside the active user's session. Depending on how many times the user has already postponed the reboot, the script will either present a "Yes/No" deferral option or a "Final Warning" that enforces the reboot after a few minutes.

Sample Run

Note:

• It is not recommended to run this script manually. The script is designed for the Autofix script of Reboot Pending Prompt - Windows Workstation compound condition.
• Prompter requires '.NET Desktop Runtime 8.0' to run. If missing, the script automatically downloads and installs it silently.
