# COM surrogate termination script (2026-02-17 05:16Z)

_**User**_

write me a script that instantly kills COM surrogate

The user wants a script that kills the COM surrogate process. COM surrogate (dllhost.exe) is a Windows process that hosts COM objects. They want to "instantly kill" it - so a script that terminates the COM surrogate process(es).

I'll create a simple script. On Windows, COM surrogate processes are typically named "dllhost.exe". I need to be careful - killing all dllhost.exe could affect other COM hosting, but the user specifically asked for killing "COM surrogate" which is what dllhost does when it's acting as a surrogate.

I'll write a PowerShell script since they're on Windows (powershell shell). The script can:
1. Find processes named dllhost.exe (these are COM surrogate when running in that role - actually all dllhost.exe are "COM surrogate" in task manager when they're the surrogate host)
2. Kill them

Or I could use a batch file with taskkill. Let me do both options - actually the user said "a script" so one is enough. PowerShell is native and they're using it.

taskkill /IM dllhost.exe /F

That would kill all dllhost processes. In Task Manager, "COM Surrogate" is the display name for dllhost.exe. So killing dllhost.exe will kill COM Surrogate.

I'll write a simple .ps1 or .bat. Batch is simpler and doesn't require execution policy changes:
taskkill /IM dllhost.exe /F

PowerShell alternative:
Get-Process -Name dllhost -ErrorAction SilentlyContinue | Stop-Process -Force

I'll create a small script. User said "only generate a script if I specify" - they did specify: "write me a script". So I'll write it.

I'll make a PowerShell script that kills dllhost (COM surrogate) and maybe show a message. Keep it concise per user rules.

Adding a short PowerShell script that forcefully terminates the COM surrogate process (dllhost.exe).

Done. The script is minimal. COM surrogate runs as dllhost.exe; stopping all dllhost processes will kill it. ErrorAction SilentlyContinue avoids errors when no such process exists. The user can run it with: powershell -ExecutionPolicy Bypass -File kill-com-surrogate.ps1 or just .\kill-com-surrogate.ps1 if execution policy allows.

Created `kill-com-surrogate.ps1`. It stops every `dllhost.exe` process (COM Surrogate). If none are running, it does nothing and doesn’t show an error.

Run it from the project folder:

```powershell
.\kill-com-surrogate.ps1
```

If scripts are blocked, run once:

```powershell
Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned
```

Or run without changing policy:

```powershell
powershell -ExecutionPolicy Bypass -File ".\kill-com-surrogate.ps1"
```

The user wants the COM surrogate kill script as a batch file instead of PowerShell. I'll create a .bat file that uses taskkill to kill dllhost.exe, and delete or replace the .ps1. I'll create the batch file and remove the ps1.

Done. Created the batch file and removed the PowerShell script. The batch uses taskkill /IM dllhost.exe /F to force-kill COM surrogate; >nul 2>&1 hides output and errors so it runs silently.

Replaced it with `kill-com-surrogate.bat`. Double-click it or run `kill-com-surrogate.bat` in a terminal; it runs with no output. The old `.ps1` file has been removed.
