打开任务管理器并单击性能选项卡。如果禁用了虚拟化，您需要按照以下说明启用它:https://blogs.technet.microsoft.com/canitpro/2015/09/08/step-by-step-enabling-hyper-v-for-use-on-windows-10/

通过“设置”开启Hyper-V角色 右键单击Windows按钮/图标，选择“应用程序和功能”。

1-选择右侧相关设置下的“程序和功能”。

2-选择“打开或关闭Windows功能”。

2-选择“Hyper-V”，单击“确定”。

我在安装VMWare后也遇到了同样的问题，我卸载了它，但这并没有解决问题。

我的解决方案:在“打开或关闭窗口功能”中，我关闭了:

hyper - v 容器 Windows Linux分系统

然后重新启动

重启后，我从docker得到了这条消息:

我执行了消息中说的命令

Enable-WindowsOptionalFeature -Online -FeatureName $("VirtualMachinePlatform", "Microsoft-Windows-Subsystem-Linux")

然后重新启动和voilà， Docker就带着WSL2回来了

I don't know how this works, and I don't even know what these commands do, I don't know what is hypervisor or what it does that it interferes with Docker, and I don't know what the nx means in the second command which it is apparently turning it off. I had these commands saved on my computer as "Turn VT-x off" (yet another thing that I don't know what it is, I think it's related to Virtualization Technology which I don't know what that does/is either). But nothing else worked for me (including the accepted answer (which I tested all of it's solutions) and other upvoted answers, although I didn't read all of them), except running both of these. It is completely up to you to test these, I do not guarantee any fixes to you, but it worked for me, I put it in here because I thought it might be helpful for someone else like me who also didn't find other answers to be that helpful:

bcdedit /set hypervisorlaunchtype auto

bcdedit /set nx AlwaysOff

shutdown /s

2023年1月10日，我遇到了同样的问题。在那之后，我取消了Linux和Hyper-v的windows子系统，重新启动我的电脑。然后我打开docker桌面，当它通知我打开Hyper-v时，我就这样做了，在那之后，它工作得很好。

@Silverstorm

我在BIOS中安装了Hyperv并启用了虚拟化。

但是A方案并不适合我。

然而，解决方案B非常有效。

解决方案B(如果Hyper-V功能已经启用但不工作)

使用

Bcdedit /set hypervisor启动类型auto 现在重新启动系统并重试。
