Powershell script to find and run advertisements that are set to run when NoUserLoggedOn

I have been thinking about how to launch a SCCM package/program before logon. If the user logs on before SCCM executes (like right after a reboot), the NoUserLoggedOn requirement will not be met. GPO software deployment handles this by not allowing the user to log in until the software is installed.

What happens if you combine both software deployment via GPO and SCCM?

So my theory is that I could execute a script wrapped in a MSI and deployed via GPO software deployment. This script would then search for advertisements that are set to run “when no one is logged in” and execute them. Below is that script, not sure if the rest of my theory will work, but this is the first piece.

$AdvNoLogOn = (gwmi -Namespace ROOT\CCM\Policy\Machine\ActualConfig -Class CCM_SoftwareDistribution | where {$_.ADV_MandatoryAssignments -eq $true} | where {$_.PRG_PRF_UserLogonRequirement -eq "NoUserLoggedOn"})
$SMSCli = [wmiclass] "\root\ccm:SMS_Client"
foreach ($Adv in $AdvNoLogOn)
{
$PKGID= $Adv.PKG_PackageID
write-host $PKGID
$SCHEDMESS=(gwmi -Namespace ROOT\CCM\Policy\Machine\ActualConfig -Class CCM_Scheduler_ScheduledMessage | where {$_.ActiveMessage -like "*$PKGID*"})
write-host $SCHEDMESS.ScheduledMessageID
$SMSCLI.TriggerSchedule($SCHEDMESS.ScheduledMessageID)
}
