How to set up WSL2 on Windows 10 and create a study environment for Linux commands

Introduction

Based on the information linked below, I set up to use WSL2 on Windows 10 and installed Ubuntu to create an environment where I can type Linux commands. [WSL2 Installation Guide for Win10] (https://docs.microsoft.com/en-us/windows/wsl/install-win10)

Unlike WSL1, WSL2 seems to have an architecture that runs the Linux kernel, and I thought it could be used as an environment for studying Linux on Windows. See the link below for the differences between WLS1 and WSL2. Differences between WSL1 and WSL2

Windows 10 environment where this procedure was performed

Edition	version	OS build	Processor
Windows 10 Pro	2004	19041.508	x64 (AMD Ryzen7 3700X)

Update Windows 10 version

Press the "Win" + "R" keys, enter "winver" and click the "OK" button.
If the OS build is "18361" or less, WSL2 cannot be used, so please upgrade.
To upgrade, press "Win" + "R" keys, enter "ms-settings: windows update" and click the "OK" button to upgrade.

Enable "Windows Subsystem for Linux" and "Virtual Machine Platform"

Press the "Win" + "R" keys, enter "Optional Features" and click the "OK" button.
Check "Windows subsystem for Linux".
Check "Virtual Machine Platform".
Reboot.

Set WSL2 to default version

Enter "PowerShell" in "Enter here to search" on the right side of the start menu and select "Run as administrator".
Execute the following command.

>wsl --set-default-version 2

I got the following error in my environment.

>wsl --set-default-version 2
error: 0x1bc
For the main differences from WSL 2, https://aka.ms/See wsl2

After updating the WSL2 kernel based on the information linked below, when I execute the command again, the error disappears. Kernel update

Install Ubuntu 20.04 LTS

Install Ubuntu from the MicroSoft Store linked below.

Ubuntu 20.04 LTS

Start WSL

Press "Win" + "R" keys, enter "wsl" and click the "OK" button, or select "Ubuntu 20.04 LTS" from the Start menu.
The command prompt is displayed and the command can be executed. (The following is the execution result of the cal command that displays the calendar)

$ cal
   September 2020

20 21 22 23 24 25 26
27 28 29 30

Finally

Now you have an environment where you can type Linux commands on Windows 10. I thought that it would be easier to create a Linux environment than creating an environment by preparing a virtual environment (Virtual BOX or Hyper-V) and installing Linux from scratch. In the future, I would like to introduce Docker in this environment and prepare the program development environment.
