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

  **Wetin make am dey wake di PC?**: One packaged app register task

  **Same thing as taskhostw?**: No. Dis one na for app background tasks

Feex tok say

If laptop wake and dis host na di name, I dey check which Store app register di trigger. I no dey delete System32\backgroundTaskHost.exe.

## Wetin bi backgroundTaskHost.exe?

backgroundTaskHost.exe na di host process for packaged-app background tasks. Di app dey declare trigger. Windows go start dis host, run di task, den e fit exit.

## Wetin e dey do?

Na sandbox host, no bi di app UI. RuntimeBroker.exe dey broker capabilities. ApplicationFrameHost.exe dey draw di window wen di app dey foreground.

## Wetin make am dey run?

Trigger don fire: timer, push, system event, or user presence. Mail and messaging apps dey call am well well. Host wey no dey exit fit bi task wey hang.

## 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 'backgroundTaskHost.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 host dey inside System32. Background tasks fit still dey annoy person. To dey annoy person no bi di same thing as fake exe wey dey Temp.

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

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

- Expected publisher: Microsoft Corporation
- Inspect di app identity, no bi only di host name
- Different from taskhostw.exe

## I fit end am?

OK for task wey hang

To end di host go cancel dat background run. Di app go register again. Use Settings > Apps to stop package wey dey continue to wake di PC.

## I fit comot am?

No

Make you no delete backgroundTaskHost.exe. You go scatter background work for every packaged app.

## E suppose start with Windows?

Triggers dey start am. Battery settings and Background apps permissions na di supported controls.

## Common wahala dem

### Laptop dey wake every few minutes

Look Background apps and di last package wey run. Di host na di container.

### Dem dey confuse am with Task Scheduler

Classic scheduled exe tasks no need dis host. Dem dey use di task image or taskhostw.

## How to troubleshoot

Diagnose before you change anything wey fit scatter things.

### Settings > Apps > di package > battery

Restrict background activity for dere. Process killers no go un-register di trigger.

### Make you no disable di host file

You go scatter every package at once.
