• 下载^(Downloads)- 显示应用下载的数据量（以 MB 为单位）。
• 上传^(Uploads)- 显示应用上传的数据量（以 MB 为单位）。

如何从Windows 10任务管理器^{(Task Manager)}中的应用历史记录^{(App history)}选项卡访问应用^{(access apps)}

虽然任务管理器^{(Task Manager)}的启动选项卡允许您禁用某些应用程序，并且可以从相应的选项卡完全管理服务，但应用程序历史记录^{(App history)}选项卡允许您访问它下面列出的任何应用程序。右键单击或按住应用程序以打开上下文菜单，然后单击或点击唯一可用的选项：切换到^{(Switch to)}。

这会导致相应的应用程序打开或其应用程序窗口^{(app window)}在前台变为活动状态。

如何在任务管理器^{(Task Manager)}的应用历史^{(App history)}选项卡中显示所有进程的历史数据

默认情况下，“应用历史记录”选项卡仅显示通过^{(App history)}Microsoft Store分发的现代应用的使用情况。但是，您可以从中获得更多信息，并让它为您的 Windows 10 设备上的所有进程显示相同的信息。单击^(Click)或点击选项^(Options)，然后点击“显示所有进程的历史记录^{("Show history for all processes)}”。

选择该选项后，任务管理器的^{(Task Manager's)} 应用历史记录选项卡会列出在您的 Windows 10^{(App history)}计算机或设备^{(computer or device)}上运行的所有应用、程序和后台进程。这使您可以全面了解上个月在您的设备上运行的进程所使用的资源。

如何使用“应用历史记录^{(App history)}”选项卡了解有关流程的更多信息

在监视您的应用历史记录^{(App history)}选项卡时，您可能会注意到进程似乎正在吞噬兆字节，就好像它们在大型比赛中是热翼一样。这可能会成为一个问题，尤其是在特定进程使用的资源稀缺的情况下，因此，如果您像我们一样，您可能希望停止任何不必要的资源使用。问题是，并非所有进程都以友好和可识别的方式命名。如果您发现自己有一个神秘的过程^{(mystery process)}，请右键单击或按住它以显示一个上下文菜单，其中提供了几个有用的选项。

单击或选项卡上的属性^(Properties)以打开列出的任何进程的属性^(Properties)窗口。

转到详细信息^(Details)选项卡以获取有关应用程序的信息列表。您也许能够找出是谁创建了它。如果您看到Microsoft、Intel或其他受信任的名称，例如您的防病毒软件名称，则它可能是必不可少的或其他重要的过程。

如果这还不够，请尝试从上下文菜单中选择在线搜索。^{(Search online)}您的默认 Web 浏览器会打开一个新选项卡并在^{(tab and searches)}Bing上搜索进程的名称（无论您的默认搜索引擎^{(default search engine)}如何）。浏览排名靠前的结果应该提供识别流程所需的所有信息，并找出^{(process and figure)}它为何使用如此多的数据分配。

在Windows 10^{(Windows 10)}的任务管理器中使用^{(Task Manager)}应用历史记录^{(App history)}选项卡的有用方法

当您习惯于在任务管理器的^{(Task Manager's)}应用历史记录选项卡中监控^{(App history)}Windows 10应用时，您会开始注意到哪些应用^{(apps use)}最常使用哪些资源。但为了让您抢先一步，以下是需要注意的应用程序类型：

CPU 时间用户^{(CPU time users)}- 您希望控制CPU用户，因为他们会浪费大量移动设备的电池寿命^{(battery life)}。显然，您长时间使用的任何应用程序都会累积CPU 时间^{(CPU time)}（使用处理器的时间量）。即使是相对轻量级的Opera ，如果你花很多^(Opera)时间上网^{(time online)}，也可以加起来。您要注意的应用程序是更大、更强大的应用程序，包括游戏和多媒体应用程序。

网络用户^{(Network users)}-浪费电池寿命^{(wasting battery life)}可能会令人烦恼，但过度使用网络可能会花钱。您要确保注意通过Internet运行的任何应用程序。这包括Opera、Google Chrome、Microsoft Edge或Mozilla Firefox等网络浏览器。

然而，比浏览器更糟糕的是流高清视频^{(HD video)}的应用程序。您可能没有意识到这一点，但当您播放最新的《权力的游戏》^{(Game of Thrones)}剧集时，整个视频文件^{(video file)}会在您观看时下载到您的设备上。您甚至可以在几个小时内积累大量数据使用，甚至无需工作。就像^(Just)Jon Snow一样，在您查看App 历史记录^{(App history)}选项卡中的使用报告之前，您一无所知。

如何在任务管理器中清除您的^{(Task Manager)}应用历史^{(App history)}数据

在查看您的应用历史数据时，很难辨别您的应用以多快的速度累积网络使用量^{(network usage)}。您可能会看到Netflix使用了大量数据，但如果该数据超过了上个月，那可能还不错。但是，如果数据记录开始后仅过了几分钟，您可能会遇到麻烦。如果您想清除数据并重新从零开始计数，请继续单击或点击“删除使用历史记录^{("Delete usage history)}”。

到目前为止收集的记录历史记录将被删除，所有列都被清零，并且“删除使用历史记录^{(Delete usage history)}”选项顶部列出的日期（通常是您所在日期的前一个月）被删除日期替换。通过仔细监控，您现在可以看到您的一些应用程序是如何快速处理数据的。

您是否打算在您的移动设备上监控您的使用历史记录？

虽然应用历史记录^{(App history)}选项卡可能没有其他任务管理器^{(Task Manager)}选项卡的普遍吸引力，但对于电池电量不足或数据计划便宜的^{(data plan)}Windows 10移动用户来说，这可能是最重要的选项卡。通过让您快速访问浪费最多资源的应用程序，它可以帮助您防止浪费、延长您的自主权并避免破坏性费用。在您关闭此选项卡之前，如果我们说服您使用“应用历史记录^{(App history)}”选项卡监控您的资源，请告知我们。你打算在什么设备上使用它？你有没有^(Did)发现什么有趣的事情？让我们知道，让我们在下面的评论中讨论。

Use the App history from Task Manager to view your apps' resource consumption

Windows 10's Task Manager can be a gold mine of information when it comes to apps and how they use your computer's resources. While most of the tabs display real-time data, the App history tab collects and reports usage statistics for the apps and programs running on your computer or device over the last month. This feature is useful, especially for users of mobile devices, like laptops, tablets, or 2-in-1 gadgets, because it helps identify apps that hog the more limited resources of such devices. Here is everything you need to know about the App history tab in Windows 10's Task Manager:

NOTE: The screenshots and the instructions in this guide apply to Windows 10 May 2019 update or newer. If you do not know what version of Windows 10 you have, read: How to check the Windows 10 version, OS build, edition, or type.

How to access the App history tab in Windows 10's Task Manager

To access the App history tab, you first need to launch the Task Manager. We found it easiest to use the keyboard shortcut "Ctrl + Shift + Esc." If you did not access this tool on Windows 10 before, it opens in the so-called compact view, providing a list of apps currently running on your device. Clicking or tapping More details opens the full version of the Task Manager.

By default, the full version of the Task Manager opens in the Processes tab. The next step is to go to the App history tab.

TIP: You can customize the Task Manager to open in any tab you want, including the App history tab.

How to customize the app data displayed in Task Manager's App history tab

The App history tab is organized in columns. You can click or tap on a column's header and drag it left or right to make it easier to view the information you are interested in. When you first open it, the App history tab displays five columns:

• Name - displays the name of the app.
• CPU Time - shows the total amount of processor time that an app has taken up.
• Network - displays the total network usage of an app in MB.
• Metered Network - displays the total network usage on a network marked as metered.
• Tile Updates - shows the amount of network usage for updating the chosen app's live tile.

By default, the apps in the list are sorted alphabetically. Clicking on any of the column headers sorts the data displayed based on the values displayed in that column.

If you right-click or press-and-hold on any of the column headers, you access a contextual menu that allows you to add more columns of data to the App history tab. Just select the columns useful to you and deselect any of the ones you are not interested in.

Here is a run-down of what the additional columns display when selected:

• Non-Metered Network - shows network usage on networks that are not marked as metered.
• Downloads - displays the amount of data downloaded by an app in MB.
• Uploads - displays the amount of data uploaded by an app in MB.

How to access apps from the App history tab in Windows 10's Task Manager

While the Startup tab of the Task Manager allows you to disable certain apps, and services can be fully managed from their corresponding tab, the App history tab lets you access any of the apps listed under it. Right-click or press-and-hold an app to open the contextual menu, and click or tap the only available option: Switch to.

This causes the corresponding app to open or its app window to become active in the foreground.

How to show historical data for all processes in Task Manager's App history tab

By default, the App history tab only displays usage for modern apps that are distributed through the Microsoft Store. However, you can get more out of it and have it display the same info for all the processes on your Windows 10 device. Click or tap Options and then "Show history for all processes."

Once that option is selected, the Task Manager's App history tab list all the apps, programs, and background processes that run on your Windows 10 computer or device. This gives you a complete overview of the resources used by processes running on your device over the last month.

How to use the App history tab to learn more about processes

When monitoring your App history tab, you might notice processes that seem to be gobbling up megabytes as if they were hot wings during the big game. This can become a problem, especially if the resources used by a particular process are scarce, so, if you are like us, you might want to put a stop to any unnecessary usage of resources. The trouble is, not all processes are named in a friendly and recognizable way. If you find yourself with a mystery process, right-click or press-and-hold on it to reveal a contextual menu that offers a couple of helpful options.

Click or tab on Properties to open the Properties window for any of the processes listed.

Go to the Details tab for a list of information about the app. You might be able to find out who created it. If you see Microsoft, Intel, or another trusted name like your antivirus' name, it is probably an essential or otherwise important process.

If this is not enough to go on, try selecting Search online from the contextual menu. Your default web browser opens a new tab and searches for the name of the process on Bing (regardless of your default search engine). Browsing through the top results should offer all the info you need to identify the process and figure out why it is using so much of your data allotment.

Useful ways to work with the App history tab in Windows 10's Task Manager

As you get used to monitoring Windows 10 apps in Task Manager's App history tab, you start to notice what apps use what resources the most. But to give you a head start, here is what sort of apps to look out for:

CPU time users - you want to keep a handle on CPU users as they waste a lot of your mobile device's battery life. Obviously, any app you use for a long time accrues CPU time (the amount of time using the processor). Even Opera, which is relatively lightweight, can add up if you spend a lot of time online. The apps you want to look out for are larger and more intense apps, including games and multimedia applications.

Network users - wasting battery life can be an annoyance, but overusing your network can cost you money. You want to make sure you pay attention to any app that operates over the Internet. That includes web browsers like Opera, Google Chrome, Microsoft Edge, or Mozilla Firefox.

Worse by far than browsers, however, are apps that stream HD video. You may not realize it, but as you stream the latest Game of Thrones episode, that entire video file is being downloaded to your device while you view. You can rack up gigs of data usage in just a few hours without even working at it. Just like Jon Snow, you know nothing until you check the usage reports in the App history tab.

How to clear your App history data in the Task Manager

When viewing your app history data, it can be difficult to discern how quickly your apps are racking up network usage. You may see that Netflix has used gigs of data, but if that data is over the last month, that may not be so bad. However, if only a few minutes have passed since data logging began, you might be in trouble. If you want to clear your data and start counting again from zero, go ahead and click or tap on "Delete usage history."

The recorded history gathered so far is deleted, all columns are zeroed out, and the date listed on top of the Delete usage history option (which is usually a month before the date you are in) is replaced by the date of the deletion. With careful monitoring, you can now see how some of your apps quickly chew up data.

Do you plan to monitor your usage history on your mobile devices?

While the App history tab may not have the universal appeal of other Task Manager tabs, to a Windows 10 mobile user with a weak battery or a cheap data plan, this is likely to be the most important tab. By giving you quick access to the apps that are wasting the most resources, it can help you prevent waste, prolong your autonomy, and avoid damaging fees. Before you close this tab, please let us know if we convinced you to monitor your resources using the App history tab. What devices do you plan to use it on? Did you find out anything interesting?
