Install the Windows Terminal from the Microsoft Store. This allows you to always be on the latest version when we release new builds with automatic upgrades.

This is our preferred method.

For users who are unable to install Windows Terminal from the Microsoft Store, released builds can be manually downloaded from this repository's Releases page.

Download the Microsoft.WindowsTerminal_<versionNumber>.msixbundle file from the Assets section. To install the app, you can simply double-click on the .msixbundle file, and the app installer should automatically run. If that fails for any reason, you can try the following command at a PowerShell prompt:

# NOTE: If you are using PowerShell 7+, please run
# Import-Module Appx -UseWindowsPowerShell
# before using Add-AppxPackage.

Add-AppxPackage Microsoft.WindowsTerminal_<versionNumber>.msixbundle

winget users can download and install the latest Terminal release by installing the Microsoft.WindowsTerminal package:

winget install --id Microsoft.WindowsTerminal -e

Chocolatey users can download and install the latest Terminal release by installing the microsoft-windows-terminal package:

choco install microsoft-windows-terminal

To upgrade Windows Terminal using Chocolatey, run the following:

choco upgrade microsoft-windows-terminal

If you have any issues when installing/upgrading the package please go to the Windows Terminal package page and follow the Chocolatey triage process

Scoop users can download and install the latest Terminal release by installing the windows-terminal package:

scoop bucket add extras
scoop install windows-terminal

To update Windows Terminal using Scoop, run the following:

scoop update windows-terminal

If you have any issues when installing/updating the package, please search for or report the same on the issues page of Scoop Extras bucket repository.

Windows Terminal Canary is a nightly build of Windows Terminal. This build has the latest code from our main branch, giving you an opportunity to try features before they make it to Windows Terminal Preview.

Windows Terminal Canary is our least stable offering, so you may discover bugs before we have had a chance to find them.

Windows Terminal Canary is available as an App Installer distribution and a Portable ZIP distribution.

The App Installer distribution supports automatic updates. Due to platform limitations, this installer only works on Windows 11.

The Portable ZIP distribution is a portable application. It will not automatically update and will not automatically check for updates. This portable ZIP distribution works on Windows 10 (19041+) and Windows 11.

Learn more about the types of Windows Terminal distributions.

Please take a few minutes to review the overview below before diving into the code:

Windows Terminal is a new, modern, feature-rich, productive terminal application for command-line users. It includes many of the features most frequently requested by the Windows command-line community including support for tabs, rich text, globalization, configurability, theming & styling, and more.

The Terminal will also need to meet our goals and measures to ensure it remains fast and efficient, and doesn't consume vast amounts of memory or power.

The Windows Console host, conhost.exe, is Windows' original command-line user experience. It also hosts Windows' command-line infrastructure and the Windows Console API server, input engine, rendering engine, user preferences, etc. The console host code in this repository is the actual source from which the conhost.exe in Windows itself is built.

Since taking ownership of the Windows command-line in 2014, the team added several new features to the Console, including background transparency, line-based selection, support for ANSI / Virtual Terminal sequences, 24-bit color, a Pseudoconsole ("ConPTY"), and more.

However, because Windows Console's primary goal is to maintain backward compatibility, we have been unable to add many of the features the community (and the team) have been wanting for the last several years including tabs, unicode text, and emoji.

These limitations led us to create the new Windows Terminal.

You can read more about the evolution of the command-line in general, and the Windows command-line specifically in this accompanying series of blog posts on the Command-Line team's blog.

While overhauling Windows Console, we modernized its codebase considerably, cleanly separating logical entities into modules and classes, introduced some key extensibility points, replaced several old, home-grown collections and containers with safer, more efficient STL containers, and made the code simpler and safer by using Microsoft's Windows Implementation Libraries - WIL.

This overhaul resulted in several of Console's key components being available for re-use in any terminal implementation on Windows. These components include a new DirectWrite-based text layout and rendering engine, a text buffer capable of storing both UTF-16 and UTF-8, a VT parser/emitter, and more.

When we started planning the new Windows Terminal application, we explored and evaluated several approaches and technology stacks. We ultimately decided that our goals would be best met by continuing our investment in our C++ codebase, which would allow us to reuse several of the aforementioned modernized components in both the existing Console and the new Terminal. Further, we realized that this would allow us to build much of the Terminal's core itself as a reusable UI control that others can incorporate into their own applications.

The result of this work is contained within this repo and delivered as the Windows Terminal application you can download from the Microsoft Store, or directly from this repo's releases.

You can configure your environment to build Terminal in one of two ways:

After cloning the repository, you can use a WinGet configuration file to set up your environment. The default configuration file installs Visual Studio 2026 Community & rest of the required tools. There are two other variants of the configuration file available in the .config directory for Enterprise & Professional editions of Visual Studio 2026. To run the default configuration file, you can either double-click the file from explorer or run the following command:

winget configure .config\configuration.winget

• You must be running Windows 10 2004 (build >= 10.0.19041.0) or later to run Windows Terminal
• You must enable Developer Mode in the Windows Settings app to locally install and run Windows Terminal
• You must have PowerShell 7 or later installed
• You must have the Windows 11 (10.0.26100) SDK installed at version 10.0.26100.8249 or greater.
• You must have at least VS 2026 version 18.6 installed
• You must install the following Workloads via the VS Installer. Note: Opening the solution will prompt you to install missing components automatically:
  • Desktop Development with C++
  • WinUI application development
• You must install the .NET Framework 4.7.2 Targeting Pack to build test projects

OpenConsole.slnx may be built from within Visual Studio or from the command-line using a set of convenience scripts & tools in the /tools directory:

Import-Module .\tools\OpenConsole.psm1
Set-MsBuildDevEnvironment
Invoke-OpenConsoleBuild

.\tools\razzle.cmd
bcz

To debug the Windows Terminal in VS, right click on CascadiaPackage (in the Solution Explorer) and go to properties. In the Debug menu, change "Application process" and "Background task process" to "Native Only".

You should then be able to build & debug the Terminal project by hitting F5. Make sure to select either the "x64" or the "x86" platform - the Terminal doesn't build for "Any Cpu" (because the Terminal is a C++ application, not a C# one).

👉 You will not be able to launch the Terminal directly by running the WindowsTerminal.exe. For more details on why, see #926, #4043

Please review these brief docs below about our coding practices.

👉 If you find something missing from these docs, feel free to contribute to any of our documentation files anywhere in the repository (or write some new ones!)

This is a work in progress as we learn what we'll need to provide people in order to be effective contributors to our project.
