Reinstall the Linux subsystem on Windows 10

I heard that Linux can be installed on Windows 10. On a whim, I rammed it up and didn't use it for a long time. As a result, I forgot the root password again. Hey, I'm too old to remember things. So check the Internet to find out how to uninstall the Linux subsystem and write a note so that you don't forget it later.

Open CMD and type lxrun, which will prompt you how to use this command, as shown below:

C:\ Users\ admin > lxrunWarning: lxrun.exe is only used to configure the legacy Windows Subsystem for Linux distribution.Distributions can be installed by visiting the Microsoft Store: https://aka.ms/wslstoreUsage: / install-Installs the subsystem Optional arguments: / y-Do not prompt user to accept or create a subsystem user / uninstall-Uninstalls the subsystem Optional arguments: / full-Perform a full uninstall / y-Do not prompt user to confirm / setdefaultuser-Sets the default subsystem user. If the user account does not exist it will be created. Optional arguments: username-Supply the username / y-If username is supplied, do not prompt to create a password

Type: lxrun / uninstall to start uninstalling the original Linux subsystem.

C:\ Users\ admin > lxrun / uninstallWarning: lxrun.exe is only used to configure the legacy Windows Subsystem for Linux distribution.Distributions can be installed by visiting the Microsoft Store: https://aka.ms/wslstoreThis will uninstall Ubuntu on Windows.This will remove the Ubuntu environment as well as any modifications and new applications with the exception of:C:\ Users\ admin\ AppData\ Local\ lxss\ homeC:\ Users\ admin\ AppData\ Local\ lxss\ rootType "y" to continue: yUninstalling...

Type bash again to check and verify that Ubuntu has been uninstalled.

C:\ Users\ admin > bashWindows Subsystem for Linux has no installed distributions.Distributions can be installed by visiting the Microsoft Store: https://aka.ms/wslstorePress any key to continue...

Next, install Ubuntu Linux and enter the command: lxrun / install

C:\ Users\ admin > lxrun / installWarning: lxrun.exe is only used to configure the legacy Windows Subsystem for Linux distribution.Distributions can be installed by visiting the Microsoft Store: https://aka.ms/wslstoreThis will install Ubuntu on Windows, distributed by Canonical and licensed under its terms available here: https://aka.ms/uowtermsType "y" to continue: yDownloading from the Microsoft Store... 100%Extracting filesystem, this will take a few minutes...Error: 0x800706ba

Damn, there is Error, but the local computer does not have permission? Check it out, I really don't have admin permission. But I tried again, and this time I succeeded.

However, I checked it on the Internet. If you try again, it still won't work. Please refer to the following methods to solve your installation failure problem:

Enable the Windows subsystem for Linux in the enable or disable Windows function below, and then try again.
