Catalog search terms comppkgsrv, component package support server

Windows, System Component

Component Package Support Server. E dey stage optional and on-demand Windows component packages. TrustedInstaller / TiWorker dey apply di component store (CBS).

## Wetin you need know

CompPkgSrv dey stage optional component packages, no be TrustedInstaller wey dey apply CBS.

CompPkgSrv.exe na Component Package Support Server. Optional features, Features on Demand, and some app-triggered packages dey pass through dis worker. TrustedInstaller.exe and TiWorker.exe still dey apply di component store. To end CompPkgSrv no dey roll back CBS apply wey don already start.

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

  **Na TrustedInstaller?**: No. Dis one dey stage optional packages

  **I suppose end am?**: Optional feature fit fail

Feex tok say

If CompPkgSrv dey busy after I add optional feature, I dey let am stage. I no dey kill TrustedInstaller to stop FOD.

## Wetin be CompPkgSrv.exe?

CompPkgSrv.exe dey stage optional component packages. Na Component Package Support Server, no be TrustedInstaller.exe wey dey apply CBS. TiWorker.exe still dey do di heavy component-store file work.

## Wetin e dey do?

E dey prepare on-demand packages wey apps and Optional features dey request. E no get di TrustedInstaller service. Spike for quality update apply na more often TiWorker.

## Wetin make am dey run?

You add optional feature, app request capability (.NET, media pack, language FOD), or Windows pre-stage package. Idle CompPkgSrv after dat work suppose commot.

## 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 'CompPkgSrv.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 CompPkgSrv.exe na Microsoft. CompPkgSrv.exe inside "debloat" zip no be am. Dis file still no dey replace TrustedInstaller as di CBS applier.

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

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

- Optional / on-demand package worker
- CBS apply: TrustedInstaller.exe and TiWorker.exe
- Expected publisher: Microsoft Corporation

## I fit end am?

Dat package fit fail

To end CompPkgSrv.exe fit fail di optional package wey e dey stage. E no dey stop TrustedInstaller mid-CBS di way wey ending TiWorker dey do. Wait if Optional features dey show progress.

## I fit comot am?

No

No delete CompPkgSrv.exe. Remove optional feature from Settings if you no want dat package. No delete TrustedInstaller to "debloat" dis host.

## E suppose start with Windows?

Optional feature or app capability dey start am. E no suppose be Startup Apps row.

## Common wahala dem

### People dey blame TrustedInstaller for every package name

Optional features and FODs dey often wake CompPkgSrv first. CBS apply na di later TrustedInstaller / TiWorker phase.

### Debloat scripts dey delete dis exe

Later Optional features and some Store apps go con fail in confusing way. Restore di system file. No copy random replacement.

## How to troubleshoot

Diagnose before you change anything wey fit scatter things.

### Settings > System > Optional features

If feature dey install, dis worker dey expected. Cancel or finish dat item. No end TrustedInstaller as di first click.

### Separate staging from CBS apply

TiWorker plus TrustedInstaller inside WinSxS na apply. CompPkgSrv inside System32 na di package support server. Match di path before you run DISM.
