如果您曾经启动任务管理器^{(Task Manager)}只是为了观察您的CPU使用率达到 100% 并停留在那里，您可能想知道为什么会出现这种突然神秘的系统资源使用率峰值。毕竟，任务管理器^{(Task Manager)}是一个轻量级程序，您可以在大多数机器上运行它而对系统性能几乎没有影响。在这篇文章中，我们将解释这个概念。

^(CPU)打开任务管理器时^{(Task Manager)}CPU使用率飙升至 100%

问题的根源在于对任务管理器^{(Task Manager)}实际工作方式的基本误解。

当您启动任务管理器^{(Task Manager)}时，它会立即开始收集有关哪些进程正在运行、哪些进程占用最多系统资源以及它们正在使用哪些资源的信息。

在任务管理器^{(Task Manager)}收集此信息时，您看到的CPU使用率峰值是任务管理器^{(Task Manager)}正在编译该数据。完成后，任务管理器^{(Task Manager)}会安定下来，并以表格格式向您显示所有数据。

当您监控不同进程的CPU使用率时，混乱会更加严重。^(CPU)解决方案是先打开任务管理器^{(Task Manager)}，这样它就可以在它开始运行时开始监控CPU使用情况，而不是在它已经开始对你的CPU征税之后。

也就是说，您也可以选择放慢任务管理器的更新速度^{( slow down the Task Manager update speed)}来跳过这个烦人的问题。由于更新会很慢，CPU使用高峰将在稍后出现。

Windows 任务管理器^{(Windows Task Manager)}提供了一种快速简便的方法来准确查看计算机上正在运行的程序以及它们当前使用的处理器和内存量。但是，如果您对它不满意，您可以查看一些可以帮助您跟踪资源使用情况的替代任务管理器工具^{(alternative Task Manager tools)}。

我希望这篇文章能够解释启动任务管理器时^{(Task Manager)}CPU突然飙升的原因。

注意事项^(NOTES)：

• 如果您正在寻找为什么您可能会在任务管理器中看到100% High Disk, CPU, or Memory usage，那么您应该阅读这篇文章。
• 如果您的任务管理器在启动时崩溃或冻结，^{(Task Manager crashes or freezes on startup)}这是您应该阅读的内容 。

CPU usage spike to 100% when opening Task Manager

If you’ve evеr launched Task Manager only to watch your CPU usage hit 100% and stay there, you may have wondered why this sudden mystery spike in system resource usage occurs. After all, Task Manager is a lightweight program that you can run with little impact on system performance on most machines. In this post, we will explain the concept.

CPU usage spikes to 100% when opening Task Manager

The root of the issue lies in a basic misunderstanding of how Task Manager actually works.

When you launch Task Manager, it immediately begins collecting information on what processes are running, which ones are taking up the most system resources, and what resources they’re using.

While Task Manager is collecting this information, the CPU usage spike you see is Task Manager compiling that data. Once it’s done, Task Manager settles down and presents all that data to you in a tabular format.

The confusion is even worse when you are monitoring CPU usage for different processes. The solution is to open Task Manager first so that it can begin monitoring CPU usage as soon as it begins running, instead of after it has already started to tax your CPU.

That said, you can also choose to slow down the Task Manager update speed to skip this annoying problem. Since the update will be slow, the CPU usage spike will come at a later point.

Windows Task Manager offers a quick and easy way to see exactly what programs are running on your computer and how much processor and memory they are currently using. However, if you are not happy with it, you can check out some alternative Task Manager tools that can help you track resource usage.

I hope the post was able to explain the reason for the sudden CPU spike when the Task Manager is launched.
