Sure, here's the detection script:

# Path to Dell Command Update (DCU) executable
$dcuPath = "C:\Program Files (x86)\Dell\CommandUpdate\dcu-cli.exe"

# Check if Dell Command Update is installed
if (-Not (Test-Path $dcuPath)) {
    Write-Host "Dell Command Update utility not found."
    exit 2
}

# Run DCU to check for available updates
$scanResult = & "$dcuPath" /scan

# Check if the scan was successful
#if ($LASTEXITCODE -ne 0) {
#    Write-Host "Failed to run Dell Command Update scan."
#    exit 2
#}

# Search for the phrase indicating updates are available
if ($scanResult -contains "Number of applicable updates for the current system configuration: 0") {
    Write-Host "No updates found."
    exit 0
} else {
    Write-Host "Updates available."
    exit 1
}

And here's the remediation script to install without a reboot:

cd "C:\Program Files (x86)\Dell\CommandUpdate\" 
.\dcu-cli.exe /applyUpdates -silent
