无论您的Windows 10计算机有多新或多旧，有时您可能会发现它开始滞后并停止响应。这通常意味着某些东西正在占用它的资源。它可能是一个占用你所有处理器的应用程序，一个消耗你所有图形资源的应用程序，使你的硬盘驱动器(drive spin)以最大速度旋转，或者在线发送大量数据。无论是其中一个，阅读本教程，了解如何识别占用系统(hog system)资源的Windows 10应用程序：
在继续之前你需要知道的
为了能够分辨出哪个Windows 10应用程序在狂热地消耗您的资源，您必须知道如何使用任务管理器(Task Manager)。您可以通过按键盘上的Control + Shift + Escape但是，这只是打开它的一种方式：我们记录了在Windows 10中启动(Windows 10)任务管理器(Task Manager)的 10 种方法。
您需要任务管理器(Task Manager)显示其详细视图，因此，如果任务管理器(Task Manager)以紧凑模式打开，请单击或点击(click or tap) 窗口左下角的更多详细信息。(More details)
除非您更改了在Task Manager中加载的默认视图(default view)，否则它应该打开Processes选项卡。如果它打开另一个选项卡，请在继续之前选择进程。(Processes)
进程(Processes)选项卡列出了 Windows 10 PC 上运行的所有进程。它们中的每一个都有一个描述性的名称，而不是一个晦涩的文件名，这可以帮助您轻松了解什么是什么。请务必注意，您可以单击或点击每个列标题，以按名称、(column header)资源使用情况(resource usage)或任何其他可用条件对进程列表重新排序。通过使用这个简单的进程(Processes)排序功能，我们可以找出哪些 Windows 10 应用程序占用了您的计算机资源。让我们看看如何：
如何识别使用所有处理器的Windows 10应用程序（ (Windows 10)CPU 使用率(CPU usage)）
查看任务管理器(Task Manager)窗口的顶部：如果您看到CPU（处理器）(CPU (Processor))运行速度很高，这可能是您的瓶颈的原因。在下面的屏幕截图中，我们的处理器是缓慢的原因。
单击或点击CPU标题可按(CPU)处理器使用情况(processor usage)按降序对进程列表进行排序。这会将占用您的处理器的任何应用程序带到列表的顶部。如果列表按升序排序，请再次单击/点击CPU标题。
如果您看到一个Windows 10应用程序显示在列表顶部，以红色或较深(darker shade)的橙色阴影显示，并且旁边有很大的百分比，那么这就是使用所有处理器的罪魁祸首。
如果有问题的应用程序占用了您的所有处理器，并且处理器使用率(processor usage)达到 90% 或更多，那么您最好关闭该应用程序，然后稍后再检查它。为此，请选择有问题的应用程序的进程，然后单击(process and click)或点击任务管理器(Task Manager)窗口右下角的结束任务。(End task)
如何识别使用所有图形资源的Windows 10应用程序（ (Windows 10)GPU 使用情况(GPU usage)）
同样，查看任务管理器(Task Manager)的顶部，如果您看到GPU（图形处理单元）(GPU (Graphics Processing Unit))很高，则您的 Windows 10 计算机滞后，因为应用程序正在使用所有图形资源。
如果单击或点击GPU标题，任务管理器(Task Manager)会按图形资源使用情况以降序对进程列表进行排序。如果列表按升序排序，请再次单击/点击GPU标题。
无论什么应用程序占用您的 GPU，都会被列在列表的顶部。如果您看到一个显示为较深的橙色阴影并且(darker shade)百分比(percent number)很大的应用程序，那么这可能是该应用程序导致您的 PC 变慢了。
如果有问题的应用程序占用了你所有的图形处理器，并且GPU 使用率(GPU usage)达到 90% 或更多，那么你最好杀死该应用程序，然后稍后再检查它。为此，请选择有问题的应用程序的进程，然后单击(process and click)或点击任务管理器(Task Manager)窗口右下角的结束任务。(End task)
如何识别密集使用网络的Windows 10应用(Windows 10)
有时，在您的Windows 10(Windows 10) PC上，一切似乎都正常运行，但互联网速度(internet speed)太慢，以至于加载网站需要很长时间。在这种情况下，您应该检查是否有Windows 10应用程序在 Internet 或网络上进行大量数据传输。
在任务管理器(Task Manager)中，点击网络(Network)数据表头，进程列表应该按照发送和接收的网络数据从大到小进行排序。如果列表按升序排序，请再次单击/点击网络(Network)标题。
在列表顶部，您现在应该看到正在密集使用您的网络连接的应用程序。如果其中任何一个显示为深橙色，并且Mbps 值(Mbps value)接近您的互联网连接最大速度(connection maximum speed)，则该应用程序可能就是您正在寻找的应用程序。这些是它在线或在网络上发送和接收大量数据的指标。
要关闭有问题的应用程序，请右键单击或点击并按住其进程，然后单击或点击结束任务(End task)。
如何识别密集使用磁盘的Windows 10应用(Windows 10)
如果您注意到 Windows 10 PC 或笔记本电脑上的硬盘驱动器LED 灯(LED light)看起来一直亮着，这意味着您的硬盘驱动器被大量使用。这通常会导致可能变得烦人的减速。要识别在 Windows 10 PC 上密集读取和写入数据的应用程序，请在任务管理器的(Task Manager)进程(Processes)选项卡中，单击或点击磁盘(Disk)数据标题。
此操作按磁盘上读取和写入的数据以降序对进程列表进行排序。如果列表按升序排序，请再次单击/点击磁盘(Disk)标题。在列表顶部，您现在应该会看到正在密集使用您的硬盘的应用程序。如果您看到其中的一个或多个显示为深橙色，并且旁边有很大的百分比数字，则这些应用程序可能正在减慢您的系统速度。
如果您想关闭过多使用硬盘的Windows 10应用程序，请右键单击或(Windows 10)点击并按住(tap and hold)它，然后在上下文菜单中按结束任务。(End task)
我们建议您在杀死系统进程时要小心
尽管关闭使系统变慢的Windows 10应用程序和进程可能很有用，但在杀死(Windows 10)系统进程(system process)es 时要小心。结束一个重要的系统进程(system process)可能会使您的系统崩溃，从而导致您丢失未保存的信息。此外，如果您打开了一个尚未保存的文件，请尝试保存它，然后再开始杀死所有应用程序和进程。
How to identify the Windows 10 apps that hog system resources
Regardless of how new or old your Windоws 10 computer is, at tіmes, yоu might find that it stаrts lagging and stops being responsive. That usually means that something is hogging its resources. It might be an aрp that takes up all your processor, onе that consumes all your graphics resоurces, makеs уour hard drive spin at maximum speed, or sends massive amounts of data online. Whether it is onе or the other, read this tutorial, and see how to identify the Windows 10 apps that hog system resources:
What you need to know before going further
To be able to tell which Windows 10 app avidly consumes your resources, you have to know how to work with Task Manager. You can quickly open it by pressing the Control + Shift + Escape keys on your keyboard. However, that's just one means of opening it: we documented 10 ways to start Task Manager in Windows 10.
You need the Task Manager to show its detailed view so, if the Task Manager opens up in its compact mode, click or tap More details at the bottom-left corner of the window.
Unless you changed the default view that loads in Task Manager, it should open the Processes tab. If it opens another tab, select Processes before going further.
The Processes tab lists all the processes running on your Windows 10 PC. Each of them has a descriptive name rather than an obscure filename, which helps you see what is what with little fuss. It is important to note that you can click or tap on each column header to reorder the list of processes by name, resource usage, or any other available criteria. By using this simple feature of sorting the Processes, we can find out which Windows 10 apps are hogging your computer's resources. Let's see how:
How to identify the Windows 10 apps that use all your processor (CPU usage)
Look at the top of the Task Manager window: if you see that the CPU (Processor) is running high, that's likely the cause of your bottleneck. In the screenshot below, our processor was the cause of slowness.
Click or tap on the CPU header to sort the processes list by processor usage, in descending order. This brings whatever applications are hogging your processor to the top of the list. If the list is sorted in ascending order, click/tap again on the CPU header.
If you see a Windows 10 app that's shown at the top of the list, in red or a darker shade of orange, and with a large percent next to it, than that is the culprit using all your processor.
If the problematic app is taking all your processor, with 90% or more of processor usage, you'd probably be better off killing the app and then checking up on it later. To do so, select the offending app's process and click or tap End task from the bottom-right corner of the Task Manager window.
How to identify the Windows 10 apps that use all the graphics resources (GPU usage)
Similarly, look at the top of the Task Manager and, if you see that the GPU (Graphics Processing Unit) is high, your Windows 10 computer is lagging because an app is using all the graphics resources.
If you click or tap the GPU header, Task Manager sorts the processes list by graphics resources usage, in descending order. If the list is sorted in ascending order, click/tap again on the GPU header.
Whatever apps are hogging your GPUs are brought to the top of the list. If you see one that's shown in a darker shade of orange and with a large percent number then that's probably the app guilty of slowing your PC down.
If the problematic app is taking all your graphic processor, with 90% or more of GPU usage, you would probably be better off killing the app and then checking up on it later. To do so, select the offending app's process and click or tap End task from the bottom-right corner of the Task Manager window.
How to identify the Windows 10 apps that use the network intensively
Sometimes, everything might seem to be working just about right on your Windows 10 PC, but the internet speed is so slow that it takes forever to load a website. In such times, you should check if there's a Windows 10 app that makes intensive data transfers on the internet or on the network.
In Task Manager, press the Network data header, and the processes list should be sorted by the network data sent and received, in descending order. If the list is sorted in ascending order, click/tap again on the Network header.
At the top of the list, you should now see the apps that are using your network connections intensively. If anyone of them is shown in dark orange and with an Mbps value that's close to your internet connection maximum speed, that app might be the one you are looking for. These are indicators that it sends and receives a lot of data online or on the network.
To close down the problematic app, right-click or tap and hold on its process, and then click or tap End task.
How to identify the Windows 10 apps that use the disk intensively
If you notice that the hard drives LED light on your Windows 10 PC or laptop looks like it's permanently lit, it means that your hard drive is used intensively. That usually leads to slowdowns that can become annoying. To identify the app that reads and writes data intensively on your Windows 10 PC, in the Processes tab from the Task Manager, click or tap the Disk data header.
This action sorts the processes list by the data read and written on the disk, in descending order. If the list is sorted in ascending order, click/tap again on the Disk header. At the top of the list, you should now see the apps that are using your hard drive(s) intensively. If you see that one or more of them are shown in dark orange and with large percent numbers next to them, those apps are probably the ones that are slowing your system.
If you want to close the Windows 10 app(s) that uses your hard drive(s) too much, right-click or tap and hold on it, and then press on End task in the contextual menu.
We advise you to be cautious when killing system processes
Although closing down the Windows 10 apps and processes that are slowing down your system can be useful, be cautious when killing system processes. Ending an important system process could crash your system, causing you to lose unsaved information. Also, if you have got a file open that you have not saved, try and save it before you start killing apps and processes all willy-nilly.
