我个人一直认为任务管理器(Task Manager)是手动覆盖按钮(override button)，用于每当计算机或其程序出现异常并且我只想关闭它或立即关闭它时。但是，任务管理器(Task Manager)实际上远不止这些。这是一个Windows 功能(Windows function)，可以提供有关各种进程、应用程序和机器内存的一般性能的详细信息。因此，虽然可以，但它可用于快速关闭计算机或终止任何程序；您可能已经注意到它还有其他几个选项卡可以执行许多其他很酷的事情。
如何打开任务管理器
打开任务管理器(Task Manager)的传统（但不是最快）方法是按住Ctrl和Alt键，然后按Delete键。请注意，这不是Backspace键，实际上是Delete键。
这将打开以下屏幕，您将在该屏幕上看到几个选项。所有这些都非常有用，并且相对不言自明。例如，如果您想退出您的个人资料，您只需在此处单击该选项，它就会执行此操作。启动任务管理器(Task Manager)是底部选项。
单击它将带您回到Windows，现在您将打开任务管理器(Task Manager)。
或者，您可以通过按住Alt和Shift并点击Escape来直接打开任务管理器(Task Manager)。很有用！
旧(Old)习惯很难改掉，但我相信我最终会接受这种方法。
现在...查看任务管理器(Task Manager)窗口，您会注意到它顶部有一排选项卡，可让您访问许多不同类型的信息。应用程序(Applications)和进程(Processes)选项卡可用于导航、了解和管理您当前正在运行的程序和进程。应用程序通常是您正在运行的程序，例如视频游戏或Microsoft Office应用程序。在进程(Processes)列表中，您会发现应用程序选项卡中列出的应用程序(Applications)以及在后台运行的Windows服务或其他不太明显的进程。
我们将在本文后面更详细地介绍这两个选项卡。其他选项卡是Services，其中详细说明了当前在您的系统上运行的各种服务；Performance，它提供有关机器硬件当前性能的数据，并且在某种程度上与Resource Monitor相关联（提供类似信息）；网络(Networking)，它提供有关计算机正在访问的当前活动互联网网络的数据；最后是Users，它将告诉您哪些用户帐户当前处于活动状态，甚至允许您与他们交流。
如何使用任务管理器中的应用程序选项卡(Task Manager)
首先，您可以使用它来关闭您当前正在运行的任何应用程序。有时应用程序可能会启动并变得无响应，而此选项卡可以帮助您快速关闭它，以便您可以重新启动它或简单地将其移开。通常(Often)，此类程序的状态将显示为“未响应”。("Not Responding.")为此，请停留在应用程序选项卡上，选择您要终止的应用程序，然后点击End Task。
这通常会弹出一个通知，基本上会警告说，如果您最近没有保存，您可能会因为强制关闭应用程序而丢失一些数据。如果您真的想关闭程序，可以继续点击“立即结束”按钮。(End Now)
在应用程序(Applications)选项卡中，您还可以找到切换到(Switch To)功能。这可以通过您打开的程序像手动和更直接的Alt-Tabbing版本一样使用。(Alt-Tabbing)要使用它，只需选择要切换到的正在运行的程序，然后单击“切换到”(Switch To)按钮。应弹出指定的程序。
您还可以使用此选项卡通过单击“新建任务”(New Task)按钮来启动新程序。
这将基本上激活一个类似于运行的窗口，您可以使用该窗口输入或浏览(Browse)并选择计算机上的任何程序并开始运行它。
输入或选择程序后，点击确定(OK)，它将开始为您运行。
如何使用任务管理器中的进程选项卡(Task Manager)
在此选项卡中，您可以查看计算机当前正在运行的所有进程。他们中的很多人可能会让您感到惊讶，您可能不知道您的计算机在背后做了多少！要查看此内容，只需单击“进程(Processes)”选项卡。请注意(Notice)，您可以以类似于结束任何程序的方式结束任何进程。请注意这一点，因为虽然其中几个进程对您来说可能看起来不熟悉，但它们对于计算机继续运行可能是必不可少的。但是，通过一些研究，您可能会发现其中一些过程是不必要的，并且会不必要地占用您的资源。在此处结束它们不会阻止它们在您下次重新启动时返回，但如果您需要内存用于其他内容，它可能会暂时释放资源。
请注意(Notice)，进程选项卡上有几列信息。默认列(default columns)，从左到右，将告诉您计算机上运行的进程的名称、运行进程的配置文件的用户名、 (User Name)CPU使用率 - 这是计算机处理器资源的百分比特定进程正在使用，Private Working Set of Memory告诉您进程正在使用多少内存，以及提供简要详细(Description)信息以帮助您识别进程可能起源的描述。
另请注意(Notice)，您可以通过单击“显示所有用户的进程”("Show processes from all users")来选择查看每个用户配置文件上运行的所有进程。这使用户名(User Name)列更加有用，您将看到系统上每个用户正在使用的进程。默认设置(default setting)通常只显示活动用户正在使用的进程。
您还可以通过单击其名称，使用任何可用列对显示的数据进行排序。
您可以在此选项卡上执行的另一个很酷的技巧是将某些功能的优先级设置为高于或低于其他功能。例如，如果您正在玩游戏或使用一个特别强大的程序并且它似乎滞后，您可能希望转移不太重要的进程的优先级并提高您正在使用的程序的优先级。不过要小心这一点；某些进程需要保持一定的优先级，否则您的系统可能会开始表现得滑稽。为此，请右键单击将弹出下拉菜单的任何进程。转到设置优先级(Set Priority)并为该功能选择您选择的优先级(priority level)。
通过右键单击，您还可以结束进程树(process tree)，即由它启动的所有进程，查看进程的文件位置(file location)，查看其属性或与之关联的服务。所有，在某些情况下很酷和有用的技巧。
关闭，暂时！
这只是对任务管理器(Task Manager)可以做的事情的一种体验。这是一个非常复杂的工具，因此我们从小处着手，并将在以后的文章中介绍其他功能和其他选项卡。如果您想继续了解它，请不要犹豫，阅读我们的后续文章：关于在Windows 7中使用任务管理器的(Task Manager)鲜为人知的技巧(Less Known Tricks)。
The Basics About the Task Manager: View, Run or End Applications and Processes
I've personally alwaуs thought of Task Manager as the manual override button for whenever a computer or one of its programs is acting strangely and I just want to close it or shut it down immediately. But, Task Manager is actually much more than that. It's a Windows function that can provide detailed information about various processes, applications, and the general performance of your machine's memory. So, while yes, it can be used to quickly shut down the computer or terminate any program; you might have noticed it also has several other tabs that do so many other cool things.
How to Open the Task Manager
The traditional (but not the fastest) way to open the Task Manager is to hold down the Ctrl and Alt keys and then press the Delete key. Note that this is not the Backspace key, but actually the Delete key.
This will bring up the following screen, on which you will see several options. All of these can be pretty useful, and are relatively self-explanatory. For example, if you wanted to log out of your profile you can simply click that option here and it will do exactly that. Start Task Manager is the bottom option.
Clicking it will take you back into Windows, only now you will have the Task Manager open.
Alternatively, you can directly open the Task Manager by holding Alt and Shift and hitting Escape. Very useful!
Old habits die hard, but I'm sure I'll eventually warm up to this method.
Now... looking at the Task Manager window, you'll notice that it has a row of tabs across the top that allow you access to many different types of information. The Applications and Processes tabs can be used to navigate, be aware of, and manage your currently actively running programs and processes. Applications are usually programs you are actively running, like video games or Microsoft Office applications. In the list of Processes you will find the applications listed in the Applications tab as well as Windows services or other less visible processes, running in the background.
We will go over these two tabs in a bit more detail, later in the article. The other tabs are Services, which details the various services currently running on your system; Performance, which gives data about the current performance of your machine's hardware and is somewhat tied to Resource Monitor (offering similar information); Networking, which gives data about the currently active internet networks the computer is accessing; and finally Users, which will tell you which user accounts are currently active and even allow you to communicate with them.
How to Use the Applications Tab from the Task Manager
First, you can use it to turn off any application you are currently running. Sometimes an application might act up and become unresponsive, and this tab can help you shut it off quickly so you can restart it or simply get it out of your way. Often, such a program's status will be shown as "Not Responding." To do this, stay on the applications tab, select the application that you'd like to terminate, and hit End Task.
This will usually bring up a notification which will basically warn that, if you haven't saved recently, you may lose some data by forcing the application to close. It's ok to go ahead and hit the End Now button if you really want to close the program.
In the Applications tab you can find also the Switch To function. This can be used a lot like a manual and more direct version of Alt-Tabbing through your open programs. To use it, simply select the running program you want to switch to and click the Switch To button. The specified program should pop up.
You can also use this tab to start a new program by clicking the New Task button.
This will basically activate a window, similar to Run, that you can use to type out or Browse and select any program on your computer and start running it.
Once you've typed or selected a program, hit OK and it will begin running for you.
How to Use the Processes Tab from the Task Manager
In this tab you can check out all of the processes your computer is currently running. A lot of them may surprise you, you might have had no idea how much your computer was doing behind your back! To give this a look, simply click the Processes tab. Notice that you can end any process in a fashion similar to ending any program. Be careful with this, as while several of those processes might seem unfamiliar to you, they might be essential for the computer to keep running. With a little research though, you might find that some of these processes aren't necessary and are needlessly taking up your resources. Ending them here won't stop them for returning the next time you reboot, but it may free up resources temporarily if you need memory for something else.
Notice that there are several columns of information here on the processes tab. The default columns, from left to right, will tell you the name of the processes running on the computer, the User Name of the profile where the process is running, CPU usage - which is a % of how much of the computer's processor's resources that specific process is using, the Private Working Set of Memory which tells you how much memory the process is using, and Description which gives brief details to help you recognize where the process may have originated.
Notice also, that you can choose to view all of the processes running on every user's profile by clicking "Show processes from all users". This makes the User Name column a bit more useful, and you will see what processes every user on the system is using. The default setting will normally only show the processes being used by the active user.
You can also sort the data displayed using any of the available columns, by clicking on its name.
Another cool trick you can do on this tab is setting the priority of certain functions as higher or lower than others. For example, if you are playing a game or working with a particularly powerful program and it seems to be lagging, you might want to divert priority from less important processes and raise the priority of a program you are working with. Be careful with this, though; some processes need to keep a certain level of priority or your system might start acting funny. To do this, right click on any process which will bring up a drop down menu. Go to Set Priority and select the priority level of your choice for that function.
With a right click you can also end a process tree, meaning all the processes that were started by it, view the file location of the process, view its properties or the services associated with it. All, cool and useful tricks in certain situations.
Closing, for now!
This is just a taste of what Task Manager can do. It's a pretty complex tool, so we're starting small and will move on to other functions and other tabs in future articles.
