Install fails at `Enable-WindowsOptionalFeature` step

[maphew]

• Your Windows build number: (Type ver at a Windows Command Prompt)

Microsoft Windows [Version 10.0.17134.48]

• What you're doing and what's happening: (Copy&paste specific commands and their output, or include screen shots)

Following instructions at https://docs.microsoft.com/en-ca/windows/wsl/install-win10 I pasted Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux into an administrator powershell console.

A "running" progress indicator appears but stays at 0% for some minutes, then fails with:

Enable-WindowsOptionalFeature : DismInitialize failed. Error code = 0x80004005
At line:1 char:1
+ Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows- ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Enable-WindowsOptionalFeature], COMException
    + FullyQualifiedErrorId : Microsoft.Dism.Commands.EnableWindowsOptionalFeatureCommand

I rebooted and tried again, same results.

• What's wrong / what should be happening instead:

Progress meter progressing to 100% then a prompt to reboot computer OR meaningful error message on why it couldn't complete.

• Strace of the failing command, if applicable: (If some_command is failing, then run strace -o some_command.strace -f some_command some_args, and link the contents of some_command.strace in a gist here).

strace -o Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux`
strace : The term 'strace' is not recognized as the name of a cmdlet, function, script file, or operable
program. Check the spelling of the name, or if a path was included, verify that the path is correct and try
again.

@maphew - Could you share you CBS.log file?

C:\windows\logs\cbs\CBS.log

[maphew]

In a bit @benhillis. I tried another route, which I'll post about after lunch, which I think may have worked. Right now I get The process cannot access the file because it is being used by another process.

After reading https://stackoverflow.com/questions/41078822/get-windowsoptionalfeature-failing-to-work I tried running Get-WindowsOptionalFeature -Online. It failed in a similar fashion to Enable, a very long pause and then an error.

Somewhere I saw reference to a GUI method via the system control panel and tried that, which seems to have worked. Start >> Windows Features >> Turn Windows Features on or off >> checkbox 'Windows Subsystem for Linux'. There was a progress bar and then prompt for reboot.

After that I opened Windows Store and selected Ubuntu. On opening it I was told "This product is installed" and then a console window opened saying "Installing, this may take a few minutes...". A bit later I was prompted to create UNIX name and password. Now Ubuntu shows in Start app list and opens a bash shell. Yay!

I then re-attempted powershell Get-WindowsOptionalFeature -Online which immediately returned many screen fulls of FeatureName : xxxx and State : Enabled or State : Disabled.

Hi Maphew
is this issue sorted? I have the same problem. Running windows 10 home ver 1803 OS build 17134.191

[maphew]

I was successful installing using the GUI (add/remove optional features, described above) but not when using the command line in the article.

I got this same error attempting to run the

Enable-WindowsOptionalFeature

from guide attempting to turn on Hyper-V here: https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/quick-start/enable-hyper-v

I was running Powershell in Administrator mode.

I couldn't turn on all the Hyper-V features via settings under this heading: Enable the Hyper-V role through Settings

It worked for me when I followed the steps under the heading: Enable Hyper-V with CMD and DISM

This turned on the Hyper-V settings I was expecting it to. This is not exactly specific to the issue in the OP but the same error brought me here, so this may help someone else out in the future
