Windows Logon. Na im get di secure attention sequence and e dey load your user session afta you sign in.

## Wetin you need know

Dis na di sign-in owner, no be leftover updater.

winlogon.exe dey handle Ctrl+Alt+Delete and e dey start di user session. To end am go sign you out. Copy wey dey outside System32 no be di Windows logon process.

- **E safe?**: Check the running file path, signature, and publisher. Name alone no fit confirm say e safe.

  **I suppose end am?**: No. E go sign you out

  **High CPU normal?**: No be like steady state

Feex tok say

If person tell you make you end winlogon to speed up di PC, I go close dat tab. Na dat process make Windows know say you don sign in.

## Wetin be winlogon.exe?

winlogon.exe na di Windows Logon Process. E dey register di secure attention sequence and e dey coordinate di desktop afta authentication.

## Wetin e dey do?

E dey launch userinit and di shell afta correct sign-in. E still dey host di lock screen hand-off to LogonUI.exe. E no dey scan files or print documents.

## Wetin make am dey run?

Every interactive session need logon owner. You dey see am because you sign in. Browser or game no start am.

## 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 'winlogon.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

Di legitimate file get Microsoft signature and e dey live inside System32. winlogon.exe inside Downloads or user temp folder no be di session owner.

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

`C:\Windows\System32\winlogon.exe`

- Expected publisher: Microsoft Corporation
- Path wey we expect: System32
- To end am dey end di session

## I fit end am?

No

To end winlogon.exe go sign you out or crash di session. E no be way to free RAM.

## I fit comot am?

No

No delete winlogon.exe. Windows no fit complete interactive logon without am.

## E suppose start with Windows?

Windows dey start winlogon as part of session setup. E no be Startup Apps leftover.

| ---------------- | -------------------------------------------------------------------------------------------------------------------------------------------- |
| Disk and network | Attribute activity to the actual process and current task; a filename alone no fit establish expected destinations or transfer volume. (pcm) |

| Signature check            | Inspect the actual file; this entry no dey certify its certificate identity. (pcm) |

## Common wahala dem

### Stuck for di lock screen

LogonUI dey draw di tiles. winlogon still get di session. Credential provider wey hang na im likely pass missing exe.

### Copy inside random folder

Malware dey reuse di name. Check di path and signature before you trust di filename.

## How to troubleshoot

Diagnose before you change anything wey fit scatter things.

### Confirm System32 and di Microsoft signature

Open properties on top di running image. User-folder path na di first red flag.

### No end am to test performance

Use Task Manager for di app wey actually dey busy. To end winlogon na to sign out.
