win10 powershell（管理员身份）操作

安装choco（windows的包管理工具类似于brew）

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

安装lxrunoffline 管理wsl的一个工具

choco install lxrunoffline -y

centos操作

win10 powershell（管理员身份）操作

lxrunoffline install -n CentOS -d D:/centos -f .
ootfs.tar.gz
wsl --set-version CentOS 2

最后强烈建议安装一下window terminal 跟wsl是绝配
