Windows 10: WslRegisterDistribution failed with error: 0x80370102

Upon the upgrade from WSL 1 to WSL 2, the requirement to have the Hyper-V feature enabled created a conflict with VirtualBox that brought VirtualBox VMs to a crawl. Because I needed VirtualBox, I was forced to disable Hyper-V and so lose access to WSL 2. Eventually, VirtualBox fixed this problem in an update, and I am now trying to reenable WSL 2, so I reenabled Hyper-V and I am running into nonsensical errors. Like WslRegisterDistribution failed with error: 0x80370102.System Specs:Microsoft Windows 11 Pro10.0.22000 Build 22000.11th Gen Intel Core i7-11850H.BIOS: VT enabled. Windows FeaturesHy

WslRegisterDistribution error 0x80370102

I am trying to install Ubuntu 20.04 LTS on my PC, but it fails with an error message.

Code:

Installing, this may take a few minutes...WslRegisterDistribution failed with error: 0x80370102Error: 0x80370102 Der virtuelle Computer konnte nicht gestartet werden, da ein erforderliches Feature nicht installiert ist.

Press any key to continue...

My laptop is an Acer E5-551G, running Windows Home version is 2004, build 19041.329. Virtualization is supported and enabled (though no special menu in the BIOS), Hyper-V is enabled and started.





The task manager also says that Virtualization is activated:





I have installed and activated WSL2 and installed the kernel update (https://aka.ms/wsl2kernel). WSL default version is set to 2.

What could be the reason for this error? I haven't found a resource explaining the error code in more detail.

Thank you in advance for any pointers.

Cheers,

Sascha

Resolving WslRegisterDistribution error 0x80370102 when installing Linux Distro for WSL 2?

# Encountering WslRegisterDistribution error 0x80370102 when installing Linux Distro for WSL 2

I am currently on the `Windows 10 Pro Insider Preview build 18922.rs_prerelease`, and am trying to install a Linux distribution to access via Windows Subsystem for Linux (2). I have tried this for both the Ubuntu and Debian distros and have encountered the
same error in each.

I have successfully downloaded both distros from the Microsoft store, but when I try to first "run" the Ubuntu or Debian "app" the respective console comes up and prints the following text:

Code:

Installing, this may take a few minutes...

WslRegisterDistribution failed with error: 0x80370102

Error: 0x80370102 The virtual machine could not be started because a required feature is not installed.

Press any key to continue...
Pressing a key at this point automatically exits the console.

## Additional information:

- Using the `wsl -l` command shows no installed distros.

- I do have Hypervisor installed and running `bcdedit` does show that `hypervisorlaunchtype` is set to `Auto` in the `Windows Boot Loader` section.

- I did previously have Ubuntu installed and working under WSL 1 before switching to the Windows Insider Program Fast Ring and gaining access to WSL 2, but I was encountering another issue when trying to have it use WSL 2. After
trying to use the command `wsl --set-version Ubuntu 2` I was met with a request to "Enable the Virtual Machine Platform". I had already run `Enable-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlatform` prior, according to the official microsoft
tutorial here Install WSL | Microsoft Docs, but for good measure I did it again and got the same error, and Ubuntu was still on version 1 (I haven't explicitly mentioned it but I was restarting/shutting down when requested/suggested
by windows and tutorials, so I don't believe me not restarting is a cause). In hopes to find a workaround, I ended up uninstalling Ubuntu and hoping I could reinstall it and have it obey the default defined by the `wsl --set-default-version 2` command (suffice
it to say, this did not go as I'd hoped).

- This might be an unrelated issue, but when I initially attempted reinstalling Ubuntu, the Microsoft store had a bit of a fit and could not complete the download- encountering an 'unknown error'. I did a restart, tried again, and
got the same error, but then after telling it to 'try again' it succeeded. I had no such issues installing Debian from the store.

## Suggestions Welcome

I've searched for a bit and can't find mention of this error code in particular anywhere else.

In addition, is there anywhere I can look up/access these error codes in any sort of documentation? Ideally so I can make a better informed work-around attempt before bothering you all on here.

All help is appreciated!
