**What privileges could an attacker gain?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.

**Determine if the Print Spooler service is running** Run the following in Windows PowerShell: Get-Service -Name Spooler If the Print Spooler is running or if the service is not disabled, follow these steps: **Stop and disable the Print Spooler service** If stopping and disabling the Print Spooler service is appropriate for your environment, run the following in Windows PowerShell: Stop-Service -Name Spooler -Force Set-Service -Name Spooler -StartupType Disabled **Impact of workaround** Stopping and disabling the Print Spooler service disables the ability to print both locally and remotely.
