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

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)
            {
            }

}

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.

在我的情况下，这是由创建eventLog源时未处理的异常引起的。使用try catch来确定原因。

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。

关闭当前打开的每个窗口，然后运行以下命令解决了我的问题:

taskkill /F /IM mmc.exe
