Uninstall then reinstall WSL on Windows 10 (clean way)

Background

I've been using wsl (version 2) with genie mod for years without issue, but one day, Windows 10 finally catch up on wsl Windows 11 features and gives us a way to use systemD natively.

I wanted to use the new "right way" to enable systemD on Windows Subsystem for Linux (without genie), and I also had a (probably related) infinite Windows RemoteApp error poping in.

Fixing it

A - Uninstall wsl and related stuff

In powershell (as admin)

WSL 2 Cisco AnyConnect Networking Workaround

Overview

WSL 2 uses a Hyper-V Virtual Network adapter. Network connectivity works without any issue when a VPN is not in use. However when a Cisco AnyConnect VPN session is established Firewall Rules and Routes are added which breaks connectivity within the WSL 2 VM. This issue is tracked WSL/issues/4277

Below outline steps to automatically configure the Interface metric on VPN connect and update DNS settings (/etc/resolv.conf) on connect/disconnect.

Manual Configuration

如何给开源项目贡献代码

分两种情况：

代码仓库管理者给你添加该仓库的写入权限，这样的话可以直接push
如果不能直接push（大多数情况），采用经典的fork & pull request来提交代码，下面讲述这种情况

fork & pull request

例如有个仓库https://github.com/ecomfe/esui.git，其采用了经典的分支开发模型，稳定后的代码提交到master分支，其余特性则在dev分支上进行开发，待成熟后合并回master分支。
