PowerShell Technical Documentation

=====================================

System Requirements

To ensure smooth installation and optimal performance of PowerShell, the following system requirements must be met:

• Operating System: Windows 10 (64-bit), Windows Server 2019 (64-bit), or later versions.
• CPU: Intel Core i5-11400F (or AMD equivalent) with at least 4 cores and 8 threads.
• RAM: 16 GB DDR4 RAM or more, recommended for high-performance configurations.
• Storage: 256 GB SSD or larger, recommended for data-intensive environments. Optional: 1 TB or larger HDD for mass storage needs.
• GPU: NVIDIA GeForce GTX 1660 Super (or AMD equivalent) with at least 4 GB of dedicated memory.
• Network Connectivity: A stable Ethernet connection is required for optimal performance. Wi-Fi connectivity may be acceptable, but it's recommended to use a wired connection when possible.

• Google Chrome (version 92+)
• Mozilla Firefox (version 88+)
• Microsoft Edge (version 79+)

Installation Guide

Prerequisites

Before proceeding with the installation process, ensure that you have:

1. A valid Windows Product Key.
2. Administrative privileges on your system.

Step-by-Step Installation Instructions

1. Download the PowerShell Installer:

Invoke-WebRequest -Uri https://aka.ms/install-powershellcore/6.4.3 -OutFile powershell.exe

2. **Run the Installer Script:**
	```powershell
& powershell.exe -NoProfile -WindowStyle Hidden -InputFormat None -ExecutionPolicy Bypass -Command "& { Add-WindowsCapability -Online -Name Microsoft.Powershell.5.0 }"

3. Wait for Installation to Complete:
   • The installation process may take a few minutes to complete.
4. Verify PowerShell Installation:

$version = (Get-ItemProperty -PathHKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\PowerShell).DisplayVersion
Write-Host "PowerShell $version installed successfully."

#### Common Issues and Solutions

* If the installation fails due to inadequate system resources, try upgrading your RAM or CPU.
* Ensure that you have a valid Windows Product Key before proceeding with the installation process.

**Post-Installation Configuration:**
After installation, you may need to configure PowerShell settings by modifying the following files:

* `C:\Users\<YourUsername>\AppData\Roaming\Microsoft\Windows\PowerShell\powershell_profile.ps1`
* `C:\Program Files\WindowsPowershell\PowerShell.exe.config`

### Technical Architecture

**Core Technologies and Frameworks:**
The PowerShell core is built on top of the .NET Core framework, which provides a robust and scalable infrastructure for scripting and automation.

**Software Architecture:**
PowerShell's software architecture consists of:

1. **Scripting Engine:** The C#-based scripting engine processes PowerShell commands.
2. **Runtime Environment:** The runtime environment provides a sandboxed environment for executing scripts.
3. **Data Storage:** PowerShell uses the `System.Collections` namespace to store data, which can be stored in various formats (e.g., CSV, JSON).

**Databases and APIs:**
PowerShell integrates with various databases and APIs, including:

1. **Active Directory:** For authentication and authorization.
2. **Azure Active Directory:** For cloud-based identity management.
3. **SQL Server:** For database interactions.
4. **RESTful APIs:** PowerShell provides extensive support for interacting with RESTful APIs.

**Performance Considerations:**
PowerShell's performance is optimized for tasks that require fast execution, memory efficiency, and minimal overhead. However, high-performance configurations may benefit from additional optimization techniques, such as:

1. **Caching mechanisms:** To reduce repetitive calculations.
2. **Parallel processing:** To take advantage of multi-core processors.

### Dependencies

**Required Libraries and Frameworks:**

* .NET Core 3.1 (or later)
* C# 7.0 (or later)

**Prerequisite Software:**
Ensure that you have the following software installed:

1. Windows 10 (64-bit), Windows Server 2019 (64-bit), or later versions.
2. A compatible web browser (recommended: Google Chrome, Mozilla Firefox, Microsoft Edge).

**Compatibility Concerns and Version Requirements:**

* PowerShell compatibility is ensured across .NET Core 3.1 (or later) and C# 7.0 (or later).
* Compatibility concerns may arise when using older versions of .NET Core or C#.
