Detection:

# Specify the registry path and key to check
$registryPath = "HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run"
$keyToCheck = "CiscoSpark"

# Check if the registry path exists
if (Test-Path $registryPath) {
    # Get the registry key
    $key = Get-ItemProperty -Path $registryPath -Name $keyToCheck -ErrorAction SilentlyContinue
    if ($key -ne $null) {
        Write-Host "Key '$keyToCheck' is present in the registry path '$registryPath'."
        Exit 1
    } else {
        Write-Host "Key '$keyToCheck' is not present in the registry path '$registryPath'."
        Exit 0
    }
} else {
    Write-Host "Registry path '$registryPath' does not exist."
    Exit 0
}

Remediation:

$registryPath = "HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run"
$keyToDelete = "CiscoSpark"
Remove-ItemProperty -Path $registryPath -Name $keyToDelete -ErrorAction SilentlyContinue
