hmmm… I haven’t used this task in a while. I’ll have to take a look at it later. It was pretty much built as a proof of concept because I didn’t like the msgbox. I’ll check it out over the weekend and if I have any reports, I’ll post here
Currently not yet. It kind of slipped my mind, so I’ll check on that in a bit. I’ve started working on a splash screen side project to run during onboarding lol.
The tricky part of that is going to be to somehow have it start and end around the session properly, and persist on reboots. That’s out of scope of this conversation, but somewhat related
@Calvin_Thain According to the Microsoft documentation for the Load method, there are 3 types of arguments it can take (that only take 1 argument): Stream, XamlReader, and XmlReader.
Seeing that the xaml is being passed as an [xml] in powershell, I assumed I would need the XmlReader. I just tested changing the following line:
And it appeared to still function correctly for me. This should help clear the ambiguity in your case, since it explicitly states which type of argument should be used.
I updated the function with the line you suggested and it does get further. What happens is it immediately cancels the session without prompting the user.

@Calvin_Thain Ah, I see. I don’t think powershell can parse the xml correctly, since the $Icon is not being set. You need to fill in the icon with an image url of your choosing (company logo maybe?). If you do not want to set the icon, you can comment out this line:
$Icon = "<Add URL to logo image here>" # <---------------------------NOTE
and remove this line from the xml:
Icon="$Icon"
Alternatively, you can add $newRunspace.SessionStateProxy.SetVariable("Icon",$Using:IconURL)
and remove $Icon = "<Add URL to logo image here>"
This way, you can create a config task text parameter for “IconURL”
Has anyone figured out a “postpone by an hour” button for this? Would be super slick if someone could say “not now” but in an hour (or a user defined timeframe with a max delay)
I don’t have time to make the necessary adjustments, but you could probably add a third button in the xaml, and then in the code-behind logic just hide the pop-up for an hour when it’s clicked (using start-sleep and setting the window to inactive/hidden). Might have to mess around with Immy’s timeout options, though, so it doesn’t cancel after like 5 minutes.
FYI, An issue I had was if the user did not select anything the prompt would stay up even if immy.bot had moved on. I was worried a user select “no” after the timeout had happened and reboot there PC anyway frustrating the user. See the updated version below with the “$dispatcherTimer” section. This script does remove the logo lines so you would have to re-add.

I am reviewing the above and am sorry if I missed anything. Has anyone solved the issue of this being a deployment and therefore running into problems where the computer may still reboot before the deployment runs…
