推荐答案

我认为你无法做到关于它的任何事情。



你确定你真的发现了泄漏吗？怎么样？并非所有方法都可靠。无论如何，如果你确实有泄漏，你无法阻止它。所有投诉都归微软所有:-(

I don''t think you can do anything about it.

Are you sure you really detected the leak? How? Not all methods are reliable. Anyway, if you do have a leak, you cannot prevent it. All complains go to Microsoft :-(
