(pcm) `Get-CimInstance -ClassName Win32_Process | Where-Object { $_.Name -eq 'RtkAudUService64.exe' } | Select-Object ProcessId, ParentProcessId, CreationDate, Name, ExecutablePath | Format-List` No result or a path we no fit access is inconclusive. Protected processes fit restrict access, and process IDs fit be reused. Keep personal paths local.
