explorer.exe 随机占用我的 CPU；对此 ProcessMonitor 日志有什么见解？

我的电脑偶尔会变得非常不响应。打开 Process Explorer 后，我发现 explorer.exe 占用了 100% 的 CPU。我四处寻找，直到找到执行此操作的线程 ID，然后使用 Process Monitor 监视该线程。该线程尝试执行许多操作。其中一些操作的结果是“成功”，而另一些操作的结果是“未找到”。我已附上包含日志的 Excel 文件，但我还附上了一个屏幕截图，其中对操作和匹配计数进行了分组/突出显示。

知道这是怎么回事吗？我运行了 AV 扫描 (Microsoft Security Essentials)，它说我没有问题。

答案1

我以前在 XP Rig 上遇到过这个问题，而且我似乎无法阻止它发生 - 这个问题似乎是一个异常事件。我能找到的唯一解决方案是通过任务管理器杀死 Explorer.exe，然后重新启动它。

只需打开任务管理器（Ctrl+Alt+Delete），导航到任务管理器中的“进程”选项卡，在“图像名称”列表下找到“Explorer.EXE”，找到后，选择它，然后按窗口右下角的“结束进程”按钮。这将终止 Explorer。

完成此操作后，返回任务管理器中的“应用程序”选项卡，按“新任务”按钮，然后在出现的对话框中输入“Explorer.EXE”。这将重新启动 Explorer 并解决问题。

答案2

explorer.exe 显然不喜欢“我的电脑”下有快捷方式。请尝试删除 target.lnk 项目，看看是否仍会出现此问题。

另一个可能的解决方法是转到控制面板>任务栏和开始菜单>开始菜单选项卡>自定义，然后向下滚动约 3/4 并选择“不搜索公共文件夹”。
