Are you running Windows 10 x64 Creators Update Home, Pro, or Enterprise (non-LTSB SKU) or later?

…

@mbloem-Steelcase — don’t think images attached to emails survive conversion into GitHub comments — could you either apply your image to the message above, or type the version number? Thanks.

Hi I’ve added the content you requested above — any thoughts on how I should proceed?

1511? That’s Threshold 2 — which was released in Nov 2015 … and is no longer supported!!

Is there a reason you’re not running a current and supported version of Win10?

You can’t enable WSL on 1511 because it’s not in 1511 — WSL was first introduced in April 2016, as a beta feature in Insiders builds released in the lead-up to Win10 1609 (Anniversary Update). WSL has received HUGE updates with each subsequent release, dramatically improving its ability to run ever more Linux tools and binaries.

• Windows 10 Creators Update: What’s new in Bash/WSL & Windows Console
• What’s new in WSL in Windows 10 Fall Creators Update
• And many of the other posts on our blog: https://blogs.msdn.microsoft.com/commandline

The current latest, supported version of WSL is available in Win10 1803 (Spring 2018 Update), and the next major Win10 release later this year will include yet more improvements and fixes.

If you’re going to run WSL, we STRONGLY encourage you to run the latest version of Windows that you can in order to get the best experience.

Thanks!

Asking my IT department about upgrading Windows now…

Hi, I have exactly the same command written as @mbloem-Steelcase but I’m running on windows 10 (familial) x64 and with the 1803 version. Can someone help me?
Thanks!

@Crozon29 — are you running Windows 10 LTSB?

Please reply with the (suitably redacted) output of running systeminfo from a PowerShell/Cmd prompt.

Hi @bitcrazed I don’t really know, when I run «gwmi win32_operatingsystem | select OperatingSystemSKU» it says 101 so I don’t think so.
I actually managed to run : Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux tonight after several attempts but I don’t have the possibility to restart my computer as said in the development to follow.
I have in output:
Path:
Online: True
RestartNeeded: False

Thank you for your help and sorry as you can see I am a beginner in this kind of stuff!

@Crozon29 gwmi win32_operatingsystem|select Version would be more useful

My guess (based on the number of times I’ve gotten it wrong myself) is that when this failed in the past, you may have omitted the -Online argument.

You must be sure to reboot your computer after enabling WSL though: WSL needs to start-up very early in the Windows bootup sequence, before any 3rd party code is loaded, to ensure a solid «chain of trust». Once enabled, you should be able to download and install your chosen distro(s) from the Windows Store.

@bitcrazed Thank you for the command.
Unfortunately I used the command » Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux » without omitting the -Online but it doesn’t work.
It’s to put in the Bash command (found on the search bar and runned as an admin)?

Hi all,
I got following message, any recommendation what to do next:

Closing this issue: For anyone else who see’s this error, note that you need to be running:

• Windows 10 x64 build 14316 or later (note — LTSB builds do not currently support WSL)
• Windows Server build 16237 or later

For the best WSL experience, we encourage you to run the most recent build of Windows that you can since WSL has improved CONSIDERABLY since its early releases.

hello. i have a same problem.
I use 17763 insider prew build. And could not turn on case sensitive feature

Same issue on Windows 10 Pro 10.0.17134. WSL is missing in «turn windows features on and off» as well as getting the error as in the OP message.

@juso — Are you running Windows 10 LTSB?

@bitcrazed — no, it’s not LTSB to my understand

@eNipu could you try using the GUI approach to install WSL? Open the start menu and search for Turn Windows Features On or Off and then check the Windows Subsystem for Linux option.

If that doesn’t work please open an issue on our WSL Github repo: https://github.com/microsoft/wsl/issues and we will help you out there.

Fixed the problem for GUI. Thanks !

Windows Subsystem for Linux is not listed in the turn windows On or Off dialogue box

@eNipu — just spotted that you’re trying to install Mircrosoft-Windows-Subsystem-Linux … which is mis-spelled.

Please run the following from an elevated PowerShell Console/Terminal:

Enable-WindowsOptionalFeature -Online -FeatureNameMicrosoft-Windows-Subsystem-Linux

Hey I have the problem, too, this is what happens when I run systeminfo

Having this same issue, I am running LTSC in Bootcamp:

PS C:Windowssystem32> Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux
Enable-WindowsOptionalFeature : Feature name Microsoft-Windows-Subsystem-Linux is unknown.

Version
-------
10.0.17763

@sambragg According to the LTSC page, you’re not running LTSC:

17763 was the fall 2018 Win10 release.

If you copy this: Get-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux, and paste it into an ELEVATED Terminal, you should see something like the following:

If not, please follow @craigloewen-msft’s instructions above.

@gibsonjc1 — Windows Server 2016 was released before WSL was first released (fall 2017).

PS C:WINDOWSsystem32> dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart

__Deployment Image Servicing and Management tool

A Windows feature name was not recognized.
Use the /Get-Features option to find the name of the feature in the image and try the command again.

The DISM log file can be found at C:WINDOWSLogsDISMdism.log__

My windows version is:

I think we’d need more info to solve the problem then. Could you please open an issue on the official WSL repo here describing your problem?

Thanks!

i don’t have Windows Subsystem for Linux option there

Hello, I’m running into the same issue and am trying the GUI method with the following selections:

Role-based or feature-based installation > Microsoft Windows Server 2016 OS (for the Server Pool)

I don’t see Windows Subsytem for Linux there either.

To install Windows Subsystem Linux, you have to enable Developer Mode in Settings App. So open Settings > Update & Security > For Developer > Developer Mode & select it to enable.

Or you may enable Developer Mode with registry tweak. Make registry script (.reg) with the following::

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionAppModelUnlock]
"AllowAllTrustedApps"=dword:1
"AllowDevelopmentWithoutDevLicense"=dword:1

Then wait some time to download the developer package. Next, open the Control Panel, click “Programs”, and click “Turn Windows Features On or Off” under Programs and Features. Enable the “Windows Subsystem for Linux (Beta)” option in the list here and click “OK”. Alternatively install WSL with commands::

1. Command Prompt:

   DISM.exe /Online /Enable-Feature /All /FeatureName:Microsoft-Windows-Subsystem-Linux /NoRestart
   

2. Powershell:

   Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux
   

Then resrtart your system and you are good to go. From Windows 10 build 16215, it is no longer required to enable Developer Mode and beta tag was removed from WSL optional component. See Windows 10 Installation Guide for further details.
