## 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 'PickerHost.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](https://feex.it/wiki/l/pcm/software/system/verify-executable-path-signature/) to compare signatures and product metadata. A filename alone no fit establish safety. (pcm)

## E dey safe?

Check dis running file

System32 PickerHost na Microsoft own. Picker exe inside crack no be di system dialog.

Compare the recorded location with the actual file. A familiar folder alone no fit establish identity. (pcm)
