You want to run:

```ahk
Run, pwsh -Command "Stop-ElgatoKeyLight -Host 192.168.1", , Hide
```  

Or using the *modern expression syntax*:

```ahk
Run, % "pwsh -Command ""Stop-ElgatoKeyLight -Host 192.168.1""", , Hide
```

---

The way your code is currently written:

```ahk
Run, pwsh, -WindowStyle Hidden -Command "Stop-ElgatoKeyLight -Host 192.168.1", Hide
```

As you pointed out, the parameters are `Target, WorkingDir, Options, OutputVarPID`, so you're trying to launch `pwsh` in the directory `-WindowStyle Hidden -Command "Stop-ElgatoKeyLight -Host 192.168.1"`.  




According to the [AHK Docs on `Run`][1], it accepts the following syntax:

```none
Run, Target , WorkingDir, Options, OutputVarPID
```

Where `Options` can include:

> * **`Max`**: launch maximized
> * **`Min`**: launch minimized
> * **`Hide`**: launch hidden (cannot be used in combination with either of the above)

I have shortcut bound to a powershell script like this:

```ahk
^4::
Run, pwsh -WindowStyle Hidden -Command "Stop-ElgatoKeyLight -Host 192.168.1"
Return
```

However, as noted in [Powershell -WindowStyle Hidden still shows a window briefly][2], this doesn't prevent a brief flash of the console starting up

I can't quite seem to get the syntax right when adding `hide`. When I try this:

```ahk
Run, pwsh, -WindowStyle Hidden -Command "Stop-ElgatoKeyLight -Host 192.168.1", Hide
```

I get the following error:

**Q**: How can I use the `hide` flag on the run command while still passing params into powershell?
