之前想在Windows上使用Linux系统，wsl很方便（为Windows用户提供了Linux环境，不需要装系统什么的）。但是不知道为什么，启动wsl的时间越来越长，从一开始的十几秒到后来的几分钟，实在让我不能忍受。我原来使用的是WSL 2，发现WSL 1 不依赖 Hyper-V 虚拟化，它直接共享 Windows 主机的 IP，启动会很快，所以试试转为 WSL 1。

过程

在 PowerShell 中逐条执行以下命令：

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16

# 1. 备份当前环境 
wsl --export Ubuntu-22.04 D:\wsl-backup.tar

# 2. 转换为 WSL 1
wsl --set-version Ubuntu-22.04 1

# 3. 彻底重启 WSL
wsl --shutdown

# 4. 测试启动速度
Measure-Command { wsl -d Ubuntu-22.04 --exec true }

# 5. 测试网络
wsl -d Ubuntu-22.04
# 进入 WSL 后，运行：
ping baidu.com

结果：

1

启动很快，网络也没有问题，暂时没发现其他问题。
