背景：我之前安装了docker desktop，发现版本不对，我就卸载了，然而重新安装时，确安装失败了

报错如下：

Docker desktop 3.1.0
Installation failed
Component CommunityInstaller.ServiceAction failed: Failed to start service: 
The service did not respond to the start or control request in a timely fashion at CommunityInstaller.Service.Service.<StartAsync>d__29.MoveNext() --- End of stack trace from previous location where exception was thrown --- 
at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) 
at CommunityInstaller.Service.Manager.<AddServiceAsync>d__23.

解决办法：

步骤1：删除服务

打开cmd 输入以下命令

sc delete Docker Desktop Service

步骤2：删除有关docker的文件

C:\Program Files\Docker

C:\Users\xxx（自己的账号目录下）\.docker

步骤3：禁用power服务

在搜索框输入msconfig.exe打开system configuration

取消勾选power并apply后重启电脑

步骤4：用管理员身份运行安装包

终于成功安装上了，安装完之后再把那个power勾选回来就行
