I have cloned a WSL distro using wsl --export and wsl --import, but now, running wsl newdistro always logs me in as root. I understand that the lxrun command is deprecated and want to avoid it. The docs recommend using distroname.exe config, but that doesn't work, since this one doesn't have a corresponding executable.

As of the time of this writing, there are at least three (let's call it 3.5) different methods of changing/setting the default user in an imported WSL instance. While the two that have already been mentioned still work, there is a Microsoft recommended way to do it that hasn't been mentioned yet in this question.

Method 1 - /etc/wsl.conf

The current Microsoft recommended way of setting the username in an instance is to create a /etc/wsl.conf in the instance with the following setting:


Changing, of course, username to be your default username.

Exit your distro/instance, then issue a wsl --terminate <distroname> from PowerShell or CMD. When you restart, the default user should be set.

This is safer and less error-prone than the registry-based methods.

Method 2 - Registry Key

Setting the registry key per @harrymc's answer.

Method 3 - LxRunOffline

Using LxRunOffline to set the registry entry, as described in @Jaime's answer. Ultimately this has the same effect as Method 2.

Semi-method 4 - Runtime user selection via wsl commandline argument

The username can be selected when starting any WSL instance by:

wsl -u username or wsl -d distroname -u username, etc.

For instance, wsl -d Ubuntu -u root.

Side Note: This question was specifically about setting the default username in an imported instance. However, for completeness, you can also set the default username for a distro that was installed from the Store (or wsl --install) with:

<distro>.exe config --default-user <username>

For instance, if you installed "Ubuntu 20.04" from the Store, you would use:

ubuntu2004.exe config --default-user <username>

The .exe here is an "App Execution Alias" in Windows. You can check the name by going to "Manage app execution aliases" in the Windows System Settings.

For readers who need to create a new user

@ndemou made a good point in the comments last year that I, in hindsight, dismissed improperly. Two other users have now mentioned in the comments that @ndemou's information was helpful. My belated apologies! Here's the additional information based on @ndemou's advice ...

Some users who find this answer may be starting up as root not because they --import'd a distribution, but possibly because the default user was never created during installation in the first place. This can happen when the distribution installation is stopped prematurely, and likely for other reasons as well.

Under Ubuntu, the default distribution for WSL, you can create your user by starting with:

wsl ~ -u root

If you need to, add the -d <distribution> option.

Then run:

useradd --create-home --shell /usr/bin/bash --user-group --groups  adm,dialout,cdrom,floppy,sudo,audio,dip,video,plugdev,netdev --password $(read -sp Password: pw ; echo $pw | openssl passwd -1 -stdin) $NEWUSER

Then set the user as the default using the /etc/wsl.conf as mentioned above.

If you've already created the user, or are using a different distribution, as @ndemou points out, make sure to also add the user either to a group that is in sudoers or directly to sudoers via visudo. See the answers to this question for additional details.

    You may want to add the new user to sudoers. If you forget it start wsl as root with something like wsl --list; wsl --distribution Ubuntu-22.04 -u root

    you are absolutely right. However it doesn't hurt to leave the comment for those like me that came here by googling and are not at the exact same situation.

    @ndemou I just realized -- If you had to add the user to sudoers in Ubuntu 22.04, then you may not have created the user correctly. Under 22.04, the normal groups that the WSL user should be in are adm cdrom sudo dip plugdev lxd (other than the $USER group, of course). As long as your user is in the sudo group, the default sudoers file will give you access without needing to edit it. Aug 2, 2022 at 22:12

    adding the entry to /etc/wsl.conf to set the default user does not appear to be working for me Oct 24, 2022 at 10:35
  • 1
    Yep. no matter what I tried it ignored the entry in /etc/wsl.conf. I ended up using the -u option in the windows terminal profile that I use to launch a shell in the distro (ie: semi-method 4 above) Oct 24, 2022 at 23:26

The normal command syntax is for example:

ubuntu config --default-user new_user_name

However, this does not work for an imported distro, which is started by the following command :

wsl --distribution <DistributionName>

(Edit: Reports were made that the above now also works for imported distros.)

Try this undocumented method:

  • Use regedit and navigate to the key:
  • Examine its subkeys for a distribution that has the right name in the item DistributionName
  • Create or modify a DWORD item named DefaultUid and set it to the user-id (uid) of your default user. Here root user is id 0 while the first user id is 1000 (0x3e8).

If this does not work for your setup, you would need to run as:

wsl --distribution ubuntu -u user_name

    The copy made with wsl --import does not contain that executable. I did wsl --export Ubuntu UbuntuFile, then wsl --import Ubuntu2 UbuntuDirectory UbuntuFile. The contents of UbuntuDirectory are rootfs, temp, fsserver and UbuntuFile. No executable. Jul 4, 2020 at 13:47
  • Yes, forgot about it : there's a gotcha with import that means you need to execute it via wsl. I corrected my answer.

  • This doesn't solve my problem. I know how to set the user for the original Ubuntu (I have two), and I know how to run the second Ubuntu, but how do I set the user for the second Ubuntu? Jul 4, 2020 at 14:01
  • Answer corrected again, hoping that this method applies to your setup. Importing distributions is not ideal.

  • Should the UID be in hexadecimal format? Jul 4, 2020 at 14:17

Verify the uid of the user that you want to set as default in your Linux console by id:

username@host:~$ id
uid=1000(username) gid=1000(username) groups=1000(username),4(adm),20(dialout),24(cdrom),25(floppy),27(sudo),29(audio),30(dip),44(video),46(plugdev),117(netdev),1001(docker)

Verify the distro name in Powershell by wsl -l -v:

PS C:\WINDOWS\system32> wsl -l -v
  NAME                   STATE           VERSION
* ubuntu-20.04           Running         2
  docker-desktop-data    Running         2
  docker-desktop         Running         2
PS C:\WINDOWS\system32>

Edit the registry in Powershell:

Get-ItemProperty Registry::HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Lxss\*\ DistributionName | Where-Object -Property DistributionName -eq ubuntu-20.04  | Set-ItemProperty -Name DefaultUid -Value 1000

Should be good by now.


If you are installing some custom distributions in WSL, you will not get a "distroname.exe" command to change the configuration. You may use LxRunOffline to change the default user. This toolset can be installed in Windows using choco install lxrunoffline.

Get the default user id of a distro

LxRunOffline allows you get and set the default user id (uid) for any installed distributions. For instance, if you have a distro named newdistro you may check the default user using gu (get default user) and -n with the name of the distribution:

lxrunoffline gu -n newdistro 

The command returns a number, the user id of the default user:

  • the root user has the 0 user-id
  • the default user created during the install has the 1000 user id.

Set the default user id for a distro

If you want to set the root as the default user, you can make it using su (set default user) with -n and the name of the distro, and -v with the user id, i.e., 0 for the root.

lxrunoffline su -n newdistro -v 0
  • Note that LxRunOffline ultimately does the same thing as the original answer - Set the registry key. However, the Microsoft recommended way is via /etc/wsl.conf (see my answer). Feb 19, 2021 at 21:18
  • You are right. I typically use lxrunoffline to support old versions of WSL running on Windows LTSB machines (that you cannot upgrade). I think using /etc/wsl.conf is a more elegant solution than lxrunoffline in Windows Build 17093 and later

If you are using Windows Terminal then you can configure a profile for your distribution.

In the Profiles settings for Windows Terminal select your distro's profile, then click the General Tab and under Command line you can use one of the previously recommended options for the wsl command.

For example, if you named your Profile Ubuntu and your username is bob, then you would set Command line to wsl.exe -d Ubuntu -u bob

While you're at it, you can configure the Starting directory, aka the one opened by default when you open a terminal for your distro with:


Using the previous example, for a distro named Ubuntu and a username of bob, you would set Starting directory to:



None of the answers worked for me on Windows 11 with an imported Ubuntu distribution. This is more than likely because my user is a domain user rather than local.

What worked is:

  1. Go into regedit and search for Lxss via Ctrl+F
  2. If it comes up with something like this: enter image description here Then edit DefaultUid and change the value to your user id from the distribution in my case it is 3e8 Hexadecimal and 1000 Decimal enter image description here

Normally went to the root user terminal edit the .bashrc

vim .bashrc

Append this line to the last of it

su - $name

    A problem with your solution is that you can use wsl to execute scripts and pipelines in Windows. I think that your solution only works if the user enter to the Linux environment. Changing the WSL configuration is a better alternative. You may check the WSL documentation and many other tools, such as WSLU and lxrunoffline

Just FYI, if you have installed distrubution other than ubuntu on WSL like OracleLinux, then command is:

OracleLinux91.exe config --default-user root

  • I am sorry @Toto but question is to "How to set default user for manually installed WSL distro?" and by this command on WSL, you can definitely do that OracleLinux91.exe config --default-user root Feb 7 at 19:08
