New-StreamDeckShell.ps1
19 Sep 2025Description
Purpose
Launches a new PowerShell console window suitable for Stream Deck buttons while running under alternate credentials.
Detailed Description
Wraps the New-Shell command to guarantee a dedicated console window is created even when invoked from hosts that hide child windows (for example, Stream Deck scripts). This function forces the RunAsUser scenario to use a separate cmd.exe process so the interactive shell remains visible.
Usage
Example 1
$credential = Get-Secret -Name 'lukeleigh.admin'
New-StreamDeckShell -Credential $credential
Example 2
$credential = Get-Secret -Name 'lukeleigh.admin'
New-StreamDeckShell -Credential $credential -Shell ‘PowerShell’ -WindowTitle ‘Admin PowerShell’
