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.

最有可能的是，删除服务失败是因为

protected override void OnStop()

停止服务时抛出错误。将内容包装在try catch中可以防止标记删除错误

protected override void OnStop()
{
            try
            {
                //things to do
            }
            catch (Exception)
            {
            }

}

如果@MainMa提供的步骤不起作用，请执行以下步骤

处理步骤步骤1尝试从windows任务管理器或使用taskkill /F /PID删除进程。你可以通过命令'sc queryex '找到进程的pid。如果仍然无法卸载，请尝试下一步。

2 .如果以上情况

运行Autoruns for Windows按名称搜索服务并删除结果。

在我的例子中，服务名称是“Monitor”，它也被一个名为“Monitor”的windows服务使用，当我试图更新我的服务时，我尝试卸载它们，安装程序试图删除windows服务“Monitor”，但它不能，安装总是回滚。

我最终将我的服务重命名为其他东西

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

打开Services控制台也可能导致这种情况。直到关闭该服务，Windows才会删除该服务。
