https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34527

Cause:  

MS vulnerability

Resolution:  

The IdP has no need for the Print Spooler service to be running. We recommend that you disable the service as per the MS article above to protect your IdP. 

Special Considerations:  

The following Powershell will enable logging for that service so that if something does happen, there is a potential trail. It will also disable the Service.

$spoolerLog = Get-LogProperties 'Microsoft-Windows-PrintService/Operational'
if ($spoolerLog.Enabled -eq $false) {
  $spoolerLog.Enabled = $true
  Set-LogProperties -LogDetails $spoolerLog
}$status = get-service -name spooler | select-object Status -ExpandProperty Status
if ($status -eq "Running") {
  stop-service -Name spooler
  set-service -name spooler -status stopped -startupType disabled
}
