Inspect the running instance

Inside Windows PowerShell, this read-only query show matching process IDs, creation times and executable paths on this PC. (pcm)

Get-CimInstance -ClassName Win32_Process | Where-Object { $_.Name -eq 'DISMHost.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. (pcm)

Use the file-identity guide to compare signatures and product metadata. A filename alone no fit establish safety. (pcm)
