在我的案例中，它在关闭服务后起了作用。检查服务。如果是，请关闭，并在任务管理器中查看是否有服务进程。

在我的情况下，我执行taskkill /f /im dongleserver.exe， 其中dongleserver.exe是我程序的exe文件。

然后我就可以重新安装我的程序了。

以下步骤:

步骤1到位置C:\Windows\Microsoft.NET\Framework\v4.0.30319

步骤2执行命令:installutil /u full-path/servicename.exe

步骤3关闭服务面板并重新打开

步骤4执行命令:installutil full-path/servicename.exe

有时，在通过PowerShell远程会话脚本删除服务时可能会发生这种情况，特别是当您试图多次删除服务时。在这种情况下，尝试在删除之前重新创建会话:

Remove-PSSession -Session $session
$newSession = New-PSSession -ComputerName $Name  -Credential $creds -ErrorAction Stop
Enter-PSSession $newSession

可能有几种原因导致服务卡在“标记为删除”中。

SysInternals' Process Explorer is opened. Closing it should lead to automatic removal of the service. Task Manager is opened. Microsoft Management Console (MMC) is opened. To ensure all instances are closed, run taskkill /F /IM mmc.exe. Services console is opened. This is the same as the previous point, since Services console is hosted by MMC. Event Viewer is opened. Again, this is the same as the third point. The key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\{service name} exists. Someone else is logged into the server and has one of the previously mentioned applications opened. An instance of Visual Studio used to debug the service is open.

发现还有一件事要检查-在任务管理器中查看-如果其他用户连接到这个框，即使他们是“断开连接”，你也必须实际签出他们才能让服务最终删除。
