用WMI查询信息，后 不显示结果

假定有一个应用程序定期通过 WMI Root\Microsoft\Windows\TaskScheduler\MSFT_ScheduledTask 为该查询计划的任务。每次运行 WMI 查询时，WMI 提供程序进程内存使用量增加。最终，内存使用率达到 WMI 提供程序进程配额，并没有更多的 WMI 查询可以进行此过程。

原因:

WMI 查询来监视计划的任务运行时，内存泄漏在 Wmiprvseexe 过程中由于出现此问题。

可以通过使用以下方法之一来获取此更新或修补程序。我们发布了通过 Windows Update 更新和 Microsoft 更新目录为 Windows Server 2012 R2。我们还发布了一个修补程序的 Windows Server 2012。即使此问题仅在 Windows Server 2012 R2 或 Windows Server 2012 中观察到，此更新还将应用于 Windows 81 和 Windows RT 81。

方法 1： Windows 更新

提供此更新为 Windows Update 上推荐更新。有关如何运行 Windows 更新的详细信息，请参阅如何通过 Windows 更新获取更新

方法 2: Microsoft 更新目录

要获得此更新的独立安装包，请转到Microsoft 更新目录网站。

最后，

您可能需要您在应用此更新或修补程序后，重新启动计算机，即可。
