Web services WsOpenServiceHost返回WS_E_OTHER

我试着在MSDN里跑步。函数WsOpenServiceHost返回错误代码0x803d0021。这个错误意味着

 MessageId: WS_E_OTHER
 Unrecognized error occurred in the Windows Web Services framework.

打印错误：

Unable to add URL to HTTP URL group.
Unrecognized error occurred in the Windows Web Services framework.
The process cannot access the file because it is being used by another process.

在Windows Web服务框架中，当尝试调试远程目标C++项目时，发生了与此相同的错误。 我已经尝试了所有可能的解决方案，我在互联网上找到了：关闭/卸载antivirusI使用MS Essentials，关闭防火墙，重新安装VS等。 但这没用

所以，我删除了所有程序，而不是上个月安装的windows更新，重新启动计算机，错误就消失了

已卸载的软件：

Foxit幻影PDF标准。Версия: 7.0.5.1021. 宽盖 清洁剂 卸载工具 以防万一，我还卸载了Microsoft Security Essentials，在bug消失后，我再次安装了它，没有任何问题。 希望，这有帮助
