## Wetin you need know

Dis na Windows aggregator host, no bi search indexer and no bi svchost.exe.

AggregatorHost.exe na System32 host wey Microsoft add for aggregated system work. Treat System32 copy as Windows. No apply svchost grouping tips give am.

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

  **Shebi na Search?**: No. SearchIndexer dey write di catalog

  **I suppose end am?**: Feature wey dey hosted fit fail

Feex tok say

If AggregatorHost na di unknown name, I dey check System32 and di publisher. I no dey end SearchIndexer sake of am.

## Wetin bi AggregatorHost.exe?

AggregatorHost.exe na Windows Aggregator Host. E bi dedicated host image, no bi service DLL inside svchost.exe.

## Wetin e dey do?

E dey aggregate work wey Microsoft no put inside explorer.exe or SearchIndexer.exe. High CPU suppose to dey read wit Process Explorer stacks, no bi wit filename risk score.

## Wetin make am dey run?

Di session or feature start di host. Copy from anywhere apart from System32 na di path check.

## 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 'AggregatorHost.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 AggregatorHost.exe wey Microsoft sign na di host. Di same filename inside Downloads no bi Windows and you no suppose run am.

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

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

- No bi SearchIndexer.exe
- No bi svchost.exe
- Path first

To end AggregatorHost.exe dey restart dat hosted work. E no bi SearchIndexer.exe and e no bi weekly svchost cleanup.

## I fit comot am?

No

No delete AggregatorHost.exe. Na System32 host. Repair wit SFC after you confirm corruption, no bi wit download.

## E suppose start with Windows?

Windows dey start am as needed. No bi vendor tray.

## Common wahala dem

### Filename mills dey invent risk percent

No public risk score dey from di name. Path and publisher na di evidence.

### High CPU without stacks

Process Explorer on dis image. No disable WSearch as first guess.

## How to troubleshoot

Diagnose before you change anything wey fit scatter things.

### Open file location

System32 na di expected answer.

### No download replacement

System file.
