# Install MDT

{% hint style="warning" %}
Microsoft Deployment Toolkit has been officially retired by Microsoft. Install it only if you have an existing MDT-based workflow that requires it.

[MDT Retirement Notice](https://learn.microsoft.com/en-us/troubleshoot/mem/configmgr/mdt/mdt-retirement)
{% endhint %}

MDT version **6.3.8456.1000** is the final release. The installer is no longer hosted on Microsoft's servers and must be downloaded from the Internet Archive.

## Install MDT with OSDeploy

The OSDeploy module handles the download, SHA256 verification, and silent installation in a single command. Administrator rights are required.

**Preview (no changes made):**

```powershell
Install-OSDeploySoftware -Name 'mdt'
```

**Install:**

```powershell
Install-OSDeploySoftware -Name 'mdt' -Force
```

**Download only (skip installation):**

```powershell
Install-OSDeploySoftware -Name 'mdt' -DownloadOnly -Force
```

The MSI is cached to `C:\ProgramData\OSDeployCore\cache\downloads\Microsoft.DeploymentToolkit_6.3.8456.1000\` and the SHA256 checksum is verified before installation proceeds.

{% hint style="info" %}
Requires PowerShell 7.6 or later running as Administrator. `curl.exe` must be available in `PATH` (included with Windows 10 1803 and later).
{% endhint %}

## Install MDT

To install MDT manually, download the MSI from the Internet Archive, verify the SHA256 checksum, and run a silent install with `msiexec`.

**Download:**

```powershell
$mdtUrl = 'https://web.archive.org/web/20250616094712/https://download.microsoft.com/download/3/3/9/339BE62D-B4B8-4956-B58D-73C4685FC492/MicrosoftDeploymentToolkit_x64.msi'
$installerPath = "$env:TEMP\MicrosoftDeploymentToolkit_x64.msi"

curl.exe --location --output $installerPath --url $mdtUrl
```

**Verify SHA256:**

```powershell
$expectedSha256 = 'dabfd183c525bdb4866d2d9324f064a291ca62f3a16ac429cf3338be529d1d58'
$actualSha256 = (Get-FileHash -Path $installerPath -Algorithm SHA256).Hash.ToLowerInvariant()

if ($actualSha256 -ne $expectedSha256) {
    throw "Checksum mismatch. Expected $expectedSha256 but got $actualSha256."
}
```

**Install silently:**

```powershell
Start-Process -FilePath 'msiexec.exe' -ArgumentList '/i', $installerPath, '/qn', '/norestart' -Wait
```

{% hint style="info" %}
Administrator rights are required for the `msiexec` install step.
{% endhint %}

## 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/microsoft-deployment-toolkit/install-mdt.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.
