With my recently released RunAsUser module there’s been an influx of questions on what it could be used for. I’ve tried to describe as much as possible on the github page and the previous blog about it. But one I wanted to talk about real quick is the ability to create Toast notifications.
Toast notifications are those little OS native notifications you side in the bottom right of your screen when receiving an e-mail. Our RMM system has the ability to create a notification using an application, but to be honest that notification looks like it came straight out of 1990.
To have a bit better user experience, and to also get the ability to do specific things with user-input I’ve decided to use Burnt Toast. Burnt Toast is a module that give you the ability to generate pretty toast messages with just a couple lines of code. Brilliant really!
Combining my RunAsUser module, and Burnt Toast we’re able to send a script to the currently logged on user’s session and get full functionality in there. One example is to reboot the computer after updates. So lets get going!
The script
The following script can be used to create a toast for reboots. It creates a ‘protocol handler’. It then toasts with a nice Gif of my logo to get the users attention. The script assumes you have trusted the PSGallery before hand.
#Checking if ToastReboot:// protocol handler is present
New-PSDrive -Name HKCR -PSProvider Registry -Root HKEY_CLASSES_ROOT -erroraction silentlycontinue | out-null
$ProtocolHandler = get-item 'HKCR:\ToastReboot' -erroraction 'silentlycontinue'
if (!$ProtocolHandler) {
#create handler for reboot
New-item 'HKCR:\ToastReboot' -force
set-itemproperty 'HKCR:\ToastReboot' -name '(DEFAULT)' -value 'url:ToastReboot' -force
set-itemproperty 'HKCR:\ToastReboot' -name 'URL Protocol' -value '' -force
new-itemproperty -path 'HKCR:\ToastReboot' -propertytype dword -name 'EditFlags' -value 2162688
New-item 'HKCR:\ToastReboot\Shell\Open\command' -force
set-itemproperty 'HKCR:\ToastReboot\Shell\Open\command' -name '(DEFAULT)' -value 'C:\Windows\System32\shutdown.exe -r -t 00' -force
}

And that’s it! you must be wondering how it looks, so lets show you that too!
And that’s it! as always, Happy PowerShelling!
