NOTE: This applies to both open source and commercial editions of Chocolatey.

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Enter your internal repository url

(this should look similar to

4. Choose your deployment method:

choco upgrade wsl2 -y --source="'STEP 3 URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:

choco upgrade wsl2 -y --source="'STEP 3 URL'"

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0

Exit $exitCode

"Windows Subsystem for Linux lets developers run a GNU/Linux environment -- including most command-line tools, utilities, and applications -- directly on Windows, unmodified, without the overhead of a traditional virtual machine or dualboot setup" - <>

Package parameters

  • /Version:1 - the version of WSL to install. Defaults to 2
  • /Retry:true - whether to retry install on logon after computer is restarted for WSL 2. Ignored when Version is 1 and it defaults to false

Example: choco install wsl2 --params "/Version:2 /Retry:true"


  • There are checks that are performed to ensure the system supports WSL 1 or 2. If any of these checks fail, the install will fail.
  • WSL 1 requires a restart before it can be used if this is a fresh install of Windows.
  • WSL 2 requires a restart before it can be installed if WSL 1 wasn't installed previously. Otherwise, it will be enabled if it detects WSL 1. <>
  • Important:
    • /Retry:true should only be set when installing WSL 2 on systems that didn't have WSL 1. Setting this param to true will schedule a self deleting task if script didn't detect WSL. That task if created will run choco install wsl2 -y -f in a powershell window after the computer is restarted.
    • /Retry:false you will have to run choco install wsl2 -f again manually after a restart if script didn't detect WSL.

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
