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

问题描述

事件 ID 4803(关闭屏幕保护程序)在事件 ID 4802(调用屏幕保护程序)之后立即触发.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开启状态.

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.

我使用的是 Windows 8.1.在 Windows 7 上，事件 ID 4803 正确发出，即在屏幕保护程序由用户交互触发后关闭.

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.

为什么事件 ID 4803 会在 4802 之后立即触发?

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 youtube 也会发生同样的事情.

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...许多视频播放器都这样做...他们阻止屏幕保护程序激活，因此事件日志指出 4802，保护程序处于活动状态，然后 4803 保护程序未激活积极的.这是按预期工作的保护程序阻塞逻辑，但这不会阻止记录事件.

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.
