同时触发Windows事件ID 4802和4803(调用和取消屏幕保护程序) [英] Windows event id 4802 and 4803 triggered at the same time (invoke & dismissal of screen saver)

问题描述

事件ID 4802(调用屏幕保护程序)后立即触发事件ID 4803(关闭屏幕保护程序).请注意，在检测到用户交互之前，屏幕保护程序实际上仍处于打开状态.

Event id 4803 (Dismissal of a screen saver) is triggered immediately after Event id 4802 (Invoking a screen saver). Note that screen saver is actually still on till user interaction is detected.

我正在使用Windows 8.1.在Windows 7上，正确显示了事件ID 4803，即在由用户交互触发的屏幕保护程序关闭之后.

I am using windows 8.1. On windows 7 Event id 4803 is emitted correctly i.e. after screen saver turns off triggered by user interaction.

为什么在4802之后立即触发事件ID 4803?

Why is Event id 4803 triggered right after 4802?

更新: 我一直在测试Windows 7的屏幕保护程序调用/关闭机制，似乎如果启用了youtube，就会发生同样的事情.

Update: I've been testing out the screen saver invoke/dismissal mechanism by windows 7 and it seems that if youtube is enabled same thing occurs.

推荐答案

这很明显...许多视频播放器都在执行此操作...他们阻止了屏幕保护程序的激活，因此事件日志指出4802保护程序处于活动状态，而4803保护程序未处于活动状态积极的.这是保护程序阻止逻辑按预期方式工作，但是并不能阻止事件被记录.

This is obvious... many video players do this... they block screensaver activation, so event log notes that 4802, saver active, then 4803 saver not active. This is the saver blocking logic working as expected, but that does not stop the events from being logged.
