Unable to Remove Windows Subsystem for Linux

Windows Version: 1809 (OS Build 17763.1098)

I am trying to setup Ubuntu 18.04 LTS in WSL. I have enabled WSL

Code:

PS C:\Windows\system32> Get-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux


FeatureName      : Microsoft-Windows-Subsystem-Linux
DisplayName      : Windows Subsystem for Linux
Description      : Provides services and environments for running native user-mode Linux shells and tools on Windows.
RestartRequired  : Possible
State            : Enabled
CustomProperties :
                   ServerComponent\Description : Provides services and environments for running native user-mode Linux
                   shells and tools on Windows.
                   ServerComponent\DisplayName : Windows Subsystem for Linux
                   ServerComponent\Id : 1033
                   ServerComponent\Type : Feature
                   ServerComponent\UniqueName : Microsoft-Windows-Subsystem-Linux
                   ServerComponent\Deploys\Update\Name : Microsoft-Windows-Subsystem-Linux

I have gone to the Windows Store and downloaded Ubuntu 18.04 LTS, but when I click launch I get the following error

Code:

Installing, this may take a few minutes...
WslRegisterDistribution failed with error: 0x8007019e
The Windows Subsystem for Linux optional component is not enabled. Please enable it and try again.
See https://aka.ms/wslinstall for details.
Press any key to continue...

I thought there might have been an error when I originally enabled WSL, so I tried to disable it, but when I do I get this error

Code:

PS C:\Windows\system32> Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux
Disable-WindowsOptionalFeature : Disable-WindowsOptionalFeature failed. Error code = 0x80004005

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Disable-WindowsOptionalFeature], COMException
    + FullyQualifiedErrorId : Microsoft.Dism.Commands.DisableWindowsOptionalFeatureCommand

Does anyone know how I can fix this?

Does WSL1 require CPU virtualisation support??

Have you executed below command:

Code:

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

After executing above command restart your computer.

Yes, I have executed that, numerous times. And yes, I have restarted, numerous times.

It seems to be working now. I did an upgrade last night (cant remember the specifics now, but it was upgrading to the latest version of Windows 10) and I also jumped into the BIOS to enable virtualisation. One, or both, of these fixed the issue I was having. Not sure what or how, but I suspect it was enabling virtualisation (even though WSL1 apparently doesnt need it??)
