You may encounter the WSL Register Distribution Failed error due to the disabled subsystem for Linux. This means there is a corrupt installation of the Linux distro application. See the following guide for more information “What is Windows Subsystem for Linux (WSL)“, How to install Windows Subsystem for Linux on Windows 11 via the Command line, and Microsoft Store, and “VirtualBox: How to install the Windows Subsystem for Linux (WSL) on Windows Server via Server Manager and PowerShell“.
This error came up when I was launching WSL Ubuntu 18.04 LTS from the Microsoft store or when I tried to launch the Linux terminal with the following message. As stated below, this error happens because the Windows Subsystem for Linux optional component is not installed.
Solution
There are various ways to go about this: Via PowerShell and the Control Panel or Windows Settings.
Via the Control or Windows Settings
