Install defaults

Download the Latest Release

To use the scripts in an operating system deployment pipeline, download the zip file ( attached to the latest release and import the extracted files into your OS deployment solution (e.g., the Microsoft Deployment Toolkit, Microsoft Endpoint Configuration Manager, etc.).

Windows Custom Defaults release hosted on GitHub


Installation of the Windows Customised Defaults is handled by Install-Defaults.ps1. When using a deployment tool such as MDT, ConfigMgr or Intune, use the following command for install:

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy RemoteSigned -File .\Install-Defaults.ps1

Enable Language Support

Install-Defaults.ps1 can install language packs and configure system-wide language settings on Windows 10 and Windows 11, for example:

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy RemoteSigned -File .\Install-Defaults.ps1 -Language "en-AU"

Use Install-Defaults.ps1 -Language "<language code>" to install language support for a specified language. Supports the bcp47 tag of the language to install; however, Skip is the default value which will skip the install of language settings.

This uses the Install-Language and Set-SystemPreferredUILanguage commands to install language packs and configure the default system language but requires minimum version Windows 10 and 11 - ensure the Windows instance is update to date for this feature to work.


Once installed, the following registry information can be used to detect that the package is installed:

  • Key - HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\f38de27b-799e-4c30-8a01-bfdedc622944
  • Value - DisplayVersion
  • Data - 2211.29.129 (the version number of the current release)

Microsoft Intune

The solution is also provided in .intunewin format to enable direct import into Microsoft Intune without re-packaging.

Settings for importing the Windows Customised Defaults as a Win32 package into Intune are maintained here: App.json. This can be used with the IntuneWin32AppPackager to automate import into Intune.

Windows Custom Defaults as a Win32 application in Microsoft Intune

To enable support for multiple languages, create multiple Win32 applications with different command lines - one for each required language.

Download and Install

To simplify download and install during an automated image build pipeline, or to install manually into an image, a quick install script is provided that can be executed with the following PowerShell:

Set-ExecutionPolicy Bypass -Scope Process -Force;
[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072;
Invoke-Expression ((New-Object System.Net.WebClient).DownloadString(""))

This will download the latest release in zip format, extract the archive and execute Install-Defaults.ps1 on the local Windows instance, to install the Windows Customised Defaults.
