Scripting Question

Prompting user to reboot PC at the end of a script?

08/07/2019 1319 views


I'm hoping to find a method of prompting a user to restart their system after a script has run, giving them the option to restart now or snooze, similar to a pending reboot when KACE is patching.

Here is an example workflow.

- Script performs an action that requires a reboot once finished.

- Dialog box is created prompting the user to restart and gives them the option to restart now or snooze. The reboot would automatically occur if there is no interaction within a set timeout such as 15 minutes.

Are there any native KACE functions or executables which can provide this functionality?

Thank you!

  • I believe this is not possible with a Script...
    • I could pull something of this nature off using PSAppDeployment Toolkit but don't want to re-invent the wheel if there are already KACE utilities that I could leverage for this task.

this is not possible natively.
If you use an OnlineKScript you can notify before run, update and destroy a message window.
After that window you could trigger a reboot with the shutdown.exe

You can use something like AutoIT to create a message window and prompt user by adding it as the last task.  Down and Dirty run a message as a batch file last and check the box to show it in the script (visible)

@echo off
echo IT dept has just finished updating blah blah software.
echo You need to restart for changes to take effect.
set /p in=Enter 1 to restart now or press enter to keep working:
echo %in%
if /I "%in%" EQU "1" shutdown /r /t 2 /f

vbscript version of this would be something like this.  It won't time out after 15 mins, but the message will be modal meaning it will remain on top of other windows till a choice is made.  I commented out the restart so you can test how it works without worrying about it rebooting.  just remove the quote before restart in the middle of the loop to use the restart function.  for the popups, you can change the timeout for them by changing the "30" to however many seconds you want to use ( say 3 while testing for example), the delay before the user is prompted again is in the sleep line, this is in milliseconds - 1 second = 1000 milliseconds, so 15 mins = 15 X 60 seconds x 1000 = 900000

this page explains msgbox if you want to play with the message box options - https://docs.microsoft.com/en-us/previous-versions/windows/internet-explorer/ie-developer/scripting-articles/sfw6660x(v=vs.84)
