Whisper

A lightweight C++ utility for executing PowerShell scripts silently with error handling and process management.

Features

• Unicode support for script paths
• Silent process execution (no window display)
• Exit code validation
• Comprehensive error logging
• Execution policy bypass capability

Usage

const std::wstring scriptPath = L"C:\\path\\to\\script.ps1";
if (RunPowerShellScript_Unicode(scriptPath)) {
    // Script executed successfully
} else {
    // Handle execution failure
}

Requirements

• Windows OS
• C++11 or later
• Visual Studio 2022 (or compatible MSVC compiler)
• Windows SDK

Building

Compile with standard Windows API libraries:

cl /EHsc main.cpp

How It Works

1. Constructs a PowerShell command with execution policy bypass
2. Creates a hidden process using CreateProcessW
3. Waits for process completion
4. Validates exit code
5. Logs errors if applicable

Parameters

• scriptPath: Full path to the PowerShell script file (.ps1)

Returns

• true: Script executed with exit code 0
• false: Execution failed or non-zero exit code
