Today, I decided to upgrade from WSL 1 to WSL 2. On WSL 1, I had no issues getting both Kali or Ubuntu to function on WSL 1. When upgrading to WSL 2, both Kali and Ubuntu failed to upgrade to version 2. I read that uninstalling and reinstalling them could fix this issue. However, upon reinstalling both of them, my system now fails to detect any installed distro, despite the distro's being installed. Launching both Kali or Ubuntu gives the same error: Error 0x80370102 Screenshot

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.

When researching this error, and from reading the official WSL 2 install guide from Microsoft, the error always seems to be because the system doesn't have virtualization enabled in the BIOS. This is really confusing as I have checked over 4 different times if I missed any virtualization setting in my BIOS, and have verified it is all enabled. I also have confirmed I have the NX feature enabled as well. Even HWiNFO detects I have virtualization enabled: Screenshot of HWiNFO's results

I have also made sure that the Virtual Machine Platform, Windows Subsystem for Linux and the Windows Hypervisor Platform features are all enabled. Not only this, but I can also create and run any number of VMs from VirtualBox without any errors or issues whatsoever.

Other troubleshooting steps I have gone through was resetting the WSL service, reset my machine (multiple times), update the WSL kernel, verify my Win version is in 19041 or above, and waited 20 minutes after boot to see if I was just being impatient.

Here is some information about my system:

  • Running Windows 10 ver 10.0.19041.388 (also known as SDK version 2004)
  • Ryzen 3900x CPU
  • 32GB DDR4 RAM
  • Asus Tuf Gaming X570-Plus Motherboard w/ BIOS ver 1407

  • Same here. Before that I was on a intel based conf. No pb.to install wsl (1 at that time) Of course you checked in your bios /advanced / cpu / that SVM mode was enabled? I hope someone has the answer. – mchko Aug 3 '20 at 14:35
  • I checked my BIOS multiple times to verify the setting in on. This is definitely a weird issue. I'm thinking it's possibly a bug WSL 2 has with some AMD CPUs, but I can't find anything to verify that. – Blu Aug 3 '20 at 14:51
  • I'm on Intel and have the same problem, virtualization is on in BIOS and the sh*t still fails with the error must be a bug with windows, annoyingly I had Ubuntu working but I have uninstalled it as I have had some other issues and now when trying to reinstall I'm hitting this error. – MMT Aug 7 '20 at 10:42
  • @MMT You did just about the same thing I did! Had Ubuntu working originally, but in my troubleshooting process, I uninstalled Ubuntu so I could reinstall it to see if maybe that would work. – Blu Aug 9 '20 at 1:22

FIRST you need to make sure you have enabled CPU virtualization in your BIOS. These instructions will depend on your hardware.

For AMD CPUs, you will look for a feature called: "AMD (AMD Secure Virtual Machine, AMD SVM)"

For Intel CPUs, you will look for a feature called: "Intel (Intel Virtualization Technology, Intel VT-x)"

Here are the instructions for setting SVM on my computer. Note: this is for a MSI motherboard.

  1. Go to advanced settings.

  2. Go into the overclocking section.

  3. Go into the CPU Features section

  4. Toggle the CPU feature "SVM Mode" which enables CPU virtualization.

SECOND you are going to have to enable the Hyper-V Windows feature.

Here are my instructions (Note feel free to duckduckgo/google this separately):

  1. Search for "Windows Features" in your taskbar.

  2. Then look for "Hyper-V". Then enable it.

At this point you should be done and no longer get this error.

    The issue I am having is that all of these steps have already been taken, and I have quadruple checked that each of those settings are enabled. I can run regular VMs through Vbox and VMware no issue. It's only WSL that refuses to work saying I don't have VM features enabled. – Blu Nov 18 '20 at 16:30
  • Unfortunately this did not work for me. I still can't run Ubuntu 20.04 on Windows 10. – Ryan Jan 22 at 1:26
  • I didn't have a feature called "Hyper-V", but I had one called "Windows Hypervisor Platform", which mentioned virtualization. I enabled it, and it worked for me. – vallentin Feb 6 at 18:18

I has fix this problem running code below and rebooting system.

bcdedit /set hypervisorlaunchtype auto

  • Welcome to Ask Ubuntu, and thanks for your answer! In the future, an even more helpful answer would mention how you knew about this command (point to the docs where you found it), what the risks of running it are, and how to revert (if possible). – Ryan Jan 22 at 1:28

you have to enable virtualisation in BIOS. There is no other way. I spent 2 hours with MS adviser on it. We done everything and ended with no success. I saw somewhere later that BIOS setting advice. It works! Virtualisation is disabled there. Once enabled Ubuntu works.

    I actually already have that setting enabled. Like I said in the post, I already checked to make sure virtualization is enabled in my BIOS, and even had a piece of software triple-check to verify it can detect virtualization is enabled. – Blu Aug 9 '20 at 1:21
  • This solved it for me. Upvoting as it is nonobvious. – Anakhand Oct 25 '20 at 9:03

It worked for me after I disabled "Virtual Machine Platform" and restart Windows. Then I turned it on again and rebooted Windows again.

This is from the May 2020 release notes:

We are aware of an issue where using the DISM (Deployment Image Servicing and Management) tool to repair corruption on systems running the May 2020 Update does not always report the correct status. This will be fixed in an upcoming servicing release.

It looks like Dism never knows when a feature is really enabled so you need to try several times until it works.

I found the solution on GitHub and some quotes were taken from there https://github.com/microsoft/WSL/issues/4120 it was just difficult for me to find a solution and therefore I am writing here here.

  • Thank you for your contribution! Please consider editing your answer and explaining a little bit what this solution is, how you implemented it and what users should expect and try when browsing that link. – Pizza Sep 26 '20 at 18:44
  • If you're wondering how to get "Virtual Machine Platform" disabled (and then enabled again) as described above, go to the control panel and search for "Turn Windows features on or off" and scroll down in the window that opens to "Virtual Machine Platform". – WebDevBooster Oct 9 '20 at 21:21
  • Unfortunately this did not work for me. I still can't run Ubuntu 20.04 on Windows 10. – Ryan Jan 22 at 1:26

Oh! I found it. In "add / remove functionnalities", you have Hyper-V and something else about virtualization. That one was missing. I only have the french translation of this func. so giving it to you won't probably help. Look for the entire list and double-check. Actually hyper-v is not required. Debian up and running.

    I tried your method and it still won't function. There are only 2 options I can see which is the Hyper-V feature, and the Virtual Machine Platform feature. The VMP feature is requires for WSL to function. Altho, weirdly enough, Powershell now tells me I need ot enable virtualization in my BIOS and enable the VMP feature. Both of which are enabled. – Blu Aug 3 '20 at 15:38

I had the same error and with the virtualization enabled too. After uncheck Windows Subsystem for Linux, Windows Hypervisor Platform and Virtual Machine Platform, restarting the pc and enable them again the error disapeared and I could install WSL 2.
