# PowerShell

PowerShell 7.6 or later is required for all OSDeploy workflows. It installs side-by-side with Windows PowerShell 5.1 and is launched using `pwsh`.

## Overview

PowerShell 7 (also called PowerShell Core) is the cross-platform, open-source successor to Windows PowerShell 5.1. It ships as a separate executable (`pwsh`) installed to `$env:ProgramFiles\PowerShell\7` and does not replace or modify the Windows PowerShell 5.1 installation. OSDeploy requires 7.6 specifically because it aligns with the minimum version tested for module compatibility and includes stability improvements for system-level operations.

## Why OSDeploy Requires PowerShell 7.6+

* The OSDeploy PowerShell Module was authored and tested against PowerShell 7.6. OSD and OSDCloud PowerShell modules require Windows PowerShell 5.1.
* Modern PowerShell APIs (`ForEach-Object -Parallel`, improved error handling) are used throughout
* `pwsh` runs in a full .NET runtime with access to system APIs needed by DISM-based operations
* OSDCloud deployments in WinPE require `pwsh` — Windows PowerShell 5.1 is not available in OSDCloud WinPE images

{% hint style="warning" %}
Do **not** install PowerShell 7 via WinGet or the Microsoft Store. Beginning with PowerShell 7.6.0, WinGet installs the MSIX package by default. MSIX packages run inside an application sandbox that blocks system-level operations, including `dism.exe`. Use the **MSI installer** for all OSDeploy scenarios.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://www.osdeploy.com/core-components/powershell.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
