Reboot Pending Prompt - Autofix [Windows]

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. The task runs SilentLauncher, which starts a branded GUI utility (OmniPrompt.exe) inside the active user's session without flashing a console window. 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.

Optionally, that final warning can hand the decision back to the user: with the reboot scheduler enabled they pick their own restart time and receive a reminder shortly before it arrives. See Reboot Scheduler & Pre-Reboot Reminder.

Install-In-Progress Protection

Before rebooting an unattended machine (no user logged in, or locked screen with the forced reboot threshold reached), the script checks whether software or updates are currently being installed. If an install is detected, the script exits cleanly without rebooting. It will try again on the next cycle after the install finishes.

This prevents the machine from restarting in the middle of a Windows Update, application installer, or feature upgrade.

The following processes and signals are checked:

Signal	What It Means
TiWorker.exe	Windows Update is actively installing an update
wusa.exe	A standalone Windows Update package is being installed
SetupHost.exe	A Windows Feature Update is in progress
MoUsoCoreWorker.exe	The Windows Update orchestrator is doing background work
Windows10Upgrader.exe	A feature upgrade using the Windows Update Agent is running
winget.exe (active)	Windows Package Manager is installing or updating software (only when actively using CPU)
MSI mutex held	An MSI installer package is currently running

Note: This check only blocks unattended reboots. If a user clicks "Yes" to reboot, the reboot happens immediately. The user made a conscious choice to restart.

Reboot Scheduler & Pre-Reboot Reminder

By default the final prompt is a single acknowledgement: the user clicks OK and the restart follows after the configured grace period. The optional scheduler changes that last step, letting the user choose their own restart time instead.

The feature is controlled entirely by cPVAL Reboot Schedule Max Hours:

Value	Behaviour of the Final Prompt
`0` or blank	Unchanged. A single OK button, and the restart follows `cPVAL Final Prompt Reboot Delay Minutes`.
Greater than `0`	A date and time picker is shown alongside a Schedule Reboot button, covering everything from now to this many hours ahead.

How a scheduled restart plays out

The user picks a time on the final prompt and clicks Schedule Reboot. The choice is written to cPVAL Scheduled Reboot Time, the prompt cycle is marked complete, and the script exits without restarting anything.
The device is left alone while it waits. The Detection automation deliberately stops detecting it, so no further prompts appear for a restart the user has already agreed to.
The reminder appears once the chosen time comes within cPVAL Reboot Reminder Lead Minutes. It states the real restart time and the actual minutes remaining, and carries a single acknowledgement button.
The restart happens at the moment the user selected. The script clears every tracking field, stamps cPVAL Reboot Reminder Sent Time, and hands the countdown to Windows through shutdown.exe, so the familiar Windows restart notification takes over.

The script exits as soon as the countdown is handed over, so it does not sit waiting.

A few edge cases are handled deliberately:

A time that has already passed, or one already inside the reminder window, is treated as "restart now" rather than scheduled. The earliest option the picker offers is the current time, so this is the honest reading of the choice.
A device switched off through its scheduled time is picked up as overdue on its next check-in and restarts late rather than never.
An installation in progress when the reminder falls due pushes the scheduled time forward by one reminder window instead of restarting through the install.
A cancelled countdown (the user runs shutdown /a, or a policy aborts it) is noticed after 60 minutes, and the device returns to the normal prompt cycle.

⚠️ Important: cPVAL Reboot Reminder Lead Minutes must be set to the same value on both this Autofix automation and the Detection automation. The Detection automation decides when a scheduled restart is due for its reminder, and this script sizes the countdown from it.

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.

OmniPrompt is a cross-platform, Go-based GUI utility that runs natively on Windows without requiring .NET runtime.

Configuration Hierarchy

The solution evaluates settings using a strict top-down hierarchy. If a value is configured at a higher priority level, it overrides the lower levels.

Priority	Level	Description
1 (Highest)	Device Level Custom Field	Overrides all lower levels. Applied to a specific endpoint.
2	Location Level Custom Field	Overrides Organization level. Applied to all endpoints in a location.
3	Organization Level Custom Field	Global default for the entire tenant.
4 (Lowest)	Script Runtime Variable	Ultimate fallback default used if the custom field is blank at all levels.

Script Variables

Instead of hardcoding defaults, the script relies on NinjaRMM Script Variables as the ultimate fallback mechanism. You can configure these variables directly in the script's settings within NinjaRMM to establish global baseline behaviors without modifying the code-signed script file.

Name	Type	Example	Default	Available Options	Description
`Prompt Title`	String/Text	`Action Required`	`Updates Installed - Reboot Required`	N/A	Title of the GUI window.
`Regular Prompt Message`	String/Text	`Security updates applied.`	Built-in standard message	N/A	Default message for regular prompts. Supports message substitution variables.
`Final Prompt Message`	String/Text	`Final warning.`	Built-in final warning message	N/A	Default message for final prompts. Supports message substitution variables.
`Prompt Count`	Integer	`5`	`4`	N/A	Max deferrals allowed before a forced reboot.
`Final Reboot Delay Minutes`	Integer	`10`	`5`	N/A	Grace period after final acknowledgment.
`Duration Between Prompts`	Integer	`6`	`4`	N/A	Minimum hours to wait between prompts.
`Regular Prompt Timeout Seconds`	Integer	`600`	`300`	N/A	Time in seconds before a Warning prompt closes automatically.
`Final Prompt Timeout Seconds`	Integer	`1200`	`900`	N/A	Time in seconds before a Final prompt closes automatically.
`Prompt Theme`	Dropdown	`Light`	`Dark`	`Dark`, `Light`	Sets the UI theme.
`Header Image`	String/Text	`https://example.com/logo.png`	(blank)	N/A	Local file path or URL for the header image.
`Icon Image`	String/Text	`C:\Logos\icon.ico`	(blank)	N/A	Local file path or URL for the icon image.
`Suppress Time Window`	String/Text	`1800-0800`	(blank)	N/A	24h time range (HHmm-HHmm) to suppress prompts.
`Max Missed Prompts Before Force`	Integer	`3`	`0`	N/A	Number of consecutive missed prompts before forcing a reboot without GUI.
`Reboot If Not Logged In`	Dropdown	`Enable`	`Disable`	`Disable`, `Enable`	Enable to reboot immediately if no user is signed in.
`Reboot During Suppress Period`	Dropdown	`Enable`	`Disable`	`Disable`, `Enable`	Fallback default. Allows unattended/forced reboots during suppress windows.
`Reboot Schedule Max Hours`	Integer	`48`	`0`	N/A	Maximum hours ahead the user may schedule their restart on the final prompt. `0` disables the scheduler and the reminder.
`Reboot Reminder Lead Minutes`	Integer	`15`	`15`	N/A	How many minutes ahead of a scheduled restart the reminder appears. Must match the Detection value.
`Reminder Prompt Title`	String/Text	`Restart Starting Soon`	`Reboot Required - Starting Soon`	N/A	Title of the pre-reboot reminder window.
`Reminder Prompt Message`	String/Text	`Your restart begins shortly.`	Built-in reminder message	N/A	Default message for the pre-reboot reminder. Supports message substitution variables.

💡 Note: Do not attempt to change default values by editing the script file directly. The PowerShell script is code-signed, and modifying the code will break the signature and prevent execution. Always use Custom Fields or Script Variables to adjust behaviors.

Message Substitution Variables

The following tokens can be used in ANY prompt message - the Regular Prompt Message, the Final Prompt Message, the Reminder Prompt Message, or their custom-field equivalents. Write them in PascalCase with NO surrounding symbols; each is replaced with its live value when the prompt is displayed.

Token	Description	Example
`PromptsToSend`	Total prompts the user will receive (regular + final)	`5`
`PromptsSent`	Number of prompts shown so far, including the current one	`2`
`PromptsLeft`	Remaining prompts before the forced/final one	`3`
`PromptIntervalMinutes`	Interval between prompts, in minutes	`240`
`PromptIntervalHours`	Same interval, in hours	`4`
`NextPromptTime`	Date and time the next prompt will appear if the user defers	`Wed 09 Sep, 6:30 PM`
`RegularTimeoutSeconds`	Regular prompt timeout, in seconds	`600`
`RegularTimeoutMinutes`	Same timeout, in minutes	`10`
`FinalTimeoutSeconds`	Final prompt timeout, in seconds	`900`
`FinalTimeoutMinutes`	Same timeout, in minutes	`15`
`DelayAfterFinalSeconds`	Delay after the final prompt before reboot, in seconds	`900`
`DelayAfterFinalMinutes`	Same delay, in minutes	`15`
`ScheduledRebootTime`	Clock time (HH:mm) of the automatic reboot. On a regular or final prompt this is now plus the final delay; on the pre-reboot reminder it is the real time the user selected	`14:30`
`MinutesUntilReboot`	Minutes until the automatic reboot. On a regular or final prompt this is the final delay; on the pre-reboot reminder it is the actual minutes remaining	`10`
`ScheduleMaxHours`	How many hours ahead the user may schedule their restart	`48`
`ScheduleMaxDays`	The same window expressed in whole days	`2`
`ScheduleWindowEnd`	Date and time of the latest moment the user may select	`Fri 11 Sep, 2:30 PM`
`ReminderLeadMinutes`	How many minutes of warning the user gets before a scheduled restart	`15`
`UptimeDays`	Whole days the machine has been running since its last restart	`23`
`LastRebootTime`	Date and time the machine was last restarted	`2026-08-17 09:14`
`ComputerName`	Machine name	`PC-OFFICE-01`
`UserName`	Logged-in username	`jsmith`

💡 Which tokens suit which prompt. Every token resolves on every prompt, but some only make sense in certain places. ScheduleMaxHours, ScheduleMaxDays and ScheduleWindowEnd belong on the final prompt when the scheduler is enabled, since that is where the user chooses a time. ReminderLeadMinutes reads naturally on the final prompt too, as a promise of the nudge to come. NextPromptTime belongs on regular prompts, where deferring is still an option. On the pre-reboot reminder there is no window left to choose from and no further prompt to come, so ScheduleWindowEnd and NextPromptTime both resolve to the scheduled restart itself.

💡 Keeping messages honest. Prefer ScheduleMaxHours or ScheduleMaxDays over writing the window into the message as prose. A message that says "within the next two days" becomes wrong the moment someone changes cPVAL Reboot Schedule Max Hours, whereas ScheduleMaxDays follows it automatically. ScheduleMaxDays rounds at the half-day mark, so 36 hours reads as 2 days; for any window under 12 hours it resolves to 0, so use ScheduleMaxHours for short windows.

💡 Note: UptimeDays and LastRebootTime are read from the operating system at display time. If either cannot be determined the token resolves to an empty string rather than failing the prompt, so avoid building a sentence that reads oddly when the value is missing.

Output

Activity Details: Logs the interaction result (e.g., "User declined reboot", "User opted to reboot", or "Final prompt acknowledged").
Custom Fields: Updates cPVAL Last Prompted and increments cPVAL Times Prompted if the user defers. Resets cPVAL Pending Reboot, cPVAL Last Prompted, cPVAL Times Prompted, cPVAL Consecutive Missed Prompts, and cPVAL First Missed Prompt Time if the reboot is initiated. Writes cPVAL Scheduled Reboot Time when a user schedules their restart, and stamps cPVAL Reboot Reminder Sent Time when the reminder is sent and the countdown begins.
User Prompt

Prompt Progression & Message Examples

The script calculates the number of remaining prompts by subtracting the times the user has already been prompted (cPVAL Times Prompted) from the maximum allowed deferrals (cPVAL Reboot Prompt Count). The user sees this count in every message they receive.

Understanding the Count

The first prompt displays the same number as cPVAL Reboot Prompt Count (e.g., 4) because this represents the total "deferrals" available. However, an additional final mandatory prompt is always added after all deferrals are exhausted. This means if you set cPVAL Reboot Prompt Count to 4, the user will receive:

4 regular prompts (Yes/No buttons) — user can defer
1 final prompt (OK button only) — reboot is mandatory
Total: 5 prompts before forced reboot

💡 Note: When the reboot scheduler is enabled through cPVAL Reboot Schedule Max Hours, the final prompt becomes a scheduling prompt rather than a plain acknowledgement, and one further pre-reboot reminder is shown shortly before the restart the user chose. The number of regular prompts is unaffected.

Sample Prompts

Example Configuration: Standard Final Prompt

Custom Field	Value
`cPVAL Pending Reboot`	`Yes`
`cPVAL Reboot Prompt Count`	`5`

Changelog

2026-09-09

Added the optional reboot scheduler. When cPVAL Reboot Schedule Max Hours is greater than 0, the final prompt presents a date and time picker so the user can choose their own restart time, and a pre-reboot reminder is shown shortly before it arrives.
Added the new custom fields cPVAL Reboot Schedule Max Hours, cPVAL Reboot Reminder Lead Minutes, cPVAL Reboot Reminder Prompt Title, cPVAL Reboot Reminder Prompt Message, cPVAL Scheduled Reboot Time, and cPVAL Reboot Reminder Sent Time.
Added the new script variables Reboot Schedule Max Hours, Reboot Reminder Lead Minutes, Reminder Prompt Title, and Reminder Prompt Message.
Leaving cPVAL Reboot Schedule Max Hours at 0 keeps the previous behaviour exactly, with no scheduler and no reminder.
The ScheduledRebootTime and MinutesUntilReboot substitution variables now resolve to the real restart time and the actual minutes remaining when used on the pre-reboot reminder.
Replaced the VBScript launcher with SilentLauncher, so the prompt no longer depends on wscript.exe. SilentLauncher is downloaded to its own directory and verified against its published hash.
The interactive wrapper script is now deployed from an embedded, code-signed and encoded copy rather than being written to disk unsigned.
Fixed the scheduled task execution time limit, which was fixed at 10 minutes and could close a longer final prompt before it timed out.
Removed setup.exe from the Install-In-Progress guard. Any unrelated vendor installer of that name would match it and defer the reboot indefinitely.
Prompt titles and messages containing an apostrophe or a percent sign are now passed through correctly.

2026-07-20

Replaced Prompter with OmniPrompt, a cross-platform Go-based GUI utility that runs natively on Windows without requiring .NET runtime.
Added new custom fields for prompt sizing and styling: cPVAL Reboot Prompt Size, cPVAL Reboot Prompt Text Box Size, cPVAL Reboot Prompt Logo Size, cPVAL Reboot Prompt Text Size, cPVAL Reboot Prompt Text Style, cPVAL Reboot Prompt Button Text Style, cPVAL Reboot Prompt Button Text Size, cPVAL Reboot Prompt Button Size, cPVAL Reboot Prompt Title Text Style, cPVAL Reboot Prompt Title Text Size, and cPVAL Reboot Prompt Title Field Size.
Added new custom field cPVAL Reboot During Suppress Period to allow unattended or forced reboots to proceed during configured suppress windows or weekends.
Converted hardcoded default values to NinjaRMM Script Variables, allowing administrators to define global fallback defaults directly within the script configuration UI.
Removed the BITS transfer job check from the Install-In-Progress guard to prevent false positives from regular background downloads (e.g., browser downloads, non-critical updates).
Added message substitution variables support for dynamic content in prompt messages.

2026-06-10

Missed prompt counter now uses real elapsed time instead of counting each script run. This makes the forced reboot timeline predictable no matter how often the detection script checks in.
Added safety checks for active installations before rebooting unattended machines. The script now looks for Windows Updates, feature upgrades, MSI installers, and winget activity.
If a forced reboot is due but an install is still running, the reboot waits until the install finishes. It will trigger automatically on the next check after the install completes.
Machines with no user logged in will no longer reboot mid-update. The script exits safely and retries on the next cycle once servicing is done.
Winget (Windows Package Manager) is only treated as active when it is actually doing work, preventing false detections from an idle process.
Script documentation updated to reflect all of the above changes.

2026-06-03

Added support for missed-prompt tracking custom fields and forced reboot threshold handling.
Added default values for suppress window behavior, missed-prompt force reboot behavior, and no-user reboot behavior.

2026-05-26

Updated the solution to install .Net 10 Desktop Runtime instead of .Net 8.
Added a default values region in the PowerShell script.

2026-03-23

Updated .Net8 Desktop Runtime installation logic to install the latest available version.
Code Signed the PowerShell script.
