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 'perfmon.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)

E dey safe?

Check dis running file

System32 perfmon.exe na Microsoft own. One perfmon.exe inside Downloads no be Microsoft own. Dis one still no be taskmgr.exe.

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

C:\Windows\System32\perfmon.exe

  • Performance Monitor launcher
  • Live process list: taskmgr.exe
  • Console host fit still show mmc.exe

I fit end am?

E dey close Performance Monitor

To end perfmon.exe dey close dat console. Task Manager go stay. Collector sets wey you don already save fit continue to run as scheduled tasks, wey no be taskmgr.

I fit comot am?

No

No delete perfmon.exe. Stop Data Collector Set from di snap-in if na dat one you wan do. No delete System32\taskmgr.exe.

E suppose start with Windows?

Na you dey launch am, or scheduled collector dey do am. Task Manager Startup apps na different list.

Common wahala dem

People dey end taskmgr dey think say dem don stop collector

Data Collector Sets dey under Performance Monitor. Task Manager na only di live view. Open perfmon to stop di log.

WmiApSrv appear and dem reset WMI

WMI-backed counter fit start di performance adapter. Dat one normal. Dis exe na still Performance Monitor, no be Task Manager.

How to troubleshoot

Diagnose before you change anything wey fit scatter things.

perfmon /rel versus Ctrl+Shift+Esc

Reliability Monitor dey dis stack. Task Manager na taskmgr.exe. Use di window wey you really want.

Stop Data Collector Sets inside di snap-in, no delete Task Manager

Scheduled logs dey survive even if you close di UI. Leave System32\perfmon.exe and taskmgr.exe where dem dey.
