Windows始终能够告诉您几乎所有您想了解的有关计算机的信息：硬件、软件、驱动程序，应有尽有。系统信息(System Information)将所有信息整齐地放在您的指尖。让我们来看看这个有用的Windows 应用程序(Windows app)，以及它可以在所有现代版本的 Windows 中向您展示您的计算机的哪些信息：
注意：(NOTE:)本指南适用于Windows 10、Windows 8.1 和Windows 7。
如何打开系统信息
在任何现代版本的Windows中，您都可以使用搜索功能(search function)来查找并打开“系统信息(System Information)”应用。使用搜索词“系统信息”(system information")或msinfo32并单击/点击具有相同名称的结果。
有关打开系统信息(System Information)的所有方法的完整指南，请参阅在Windows（所有版本）中启动系统信息的 10 种方法。(System Information)
系统信息(System Information)里面有什么
当系统信息(System Information)打开时，您会看到系统摘要，其中包括操作系统名称、版本、系统名称、系统制造商(OS Name, Version, System Name, System Manufacturer)等。如果您阅读了摘要，您将了解有关您的Windows 计算机或设备(Windows computer or device)的基础知识。在左侧，有几个类别。左侧窗格(left pane)中的每个类别在右侧都有展开的详细信息。主要类别是硬件资源(Hardware Resources)、组件(Components,)和软件环境。(Software Environment.)
要展开类别并查看其详细信息，请双击或双击其名称。然后您会看到几个子类别。单击他们的名字会在应用程序窗口(app window)的右侧加载有用的信息。
如何使用搜索功能在(Search feature)系统信息(System Information)中查找您想要的信息
在系统信息的底部，(System Information,)有一个查找内容(Find what)框，您可以在其中搜索特定信息。如果未显示该框，请在“编辑”菜单中选择“(Edit)隐藏查找(Hide Find)”或按键盘上的CTRL + F您可以使用相同的步骤再次隐藏它。您也可以通过按关闭查找(Close Find)按钮来隐藏搜索框。(search box)
例如，如果您想查找计算机的 IP（互联网协议）地址，您可以在框中输入IP 地址(IP Address)并单击/点击查找(Find)。在这种特殊情况下，您可能需要按几次Find Next ，直到找到活动的(Find Next)网络连接(network connection)。
使用您想要的关键字尝试搜索功能(search feature)，看看它是如何工作的。
如何使用系统信息(System Information)查看有关硬件的详细信息
硬件资源(Hardware Resources)类别充满了技术细节。它主要是为专家用户或 IT 专业人员设计的。如果不准确查找技术术语的含义，普通用户可能找不到任何有用的东西。
有一个名为Conflicts/Sharing的部分可能包含也可能不包含任何内容，具体取决于您的系统设置方式。在DOS时代和早期的Windows中，IRQ（“中断请求”）(interrupt request"))冲突是一件大事，您通常不得不反复摆弄和转移事物，这样您的设备就不会为了相同的资源而相互争斗. 这不再是问题，因此Conflicts/Sharing部分仅用于提供信息，而不是问题警告。
如果您想了解有关分配了哪些 IRQ 的更多信息，请单击(IRQs)或点击(click or tap)IRQ 部分(IRQs section)。
系统信息(System Information)中的组件(Components)部分详细介绍了系统上安装的硬件设备。在我们的计算机上，多媒体(Multimedia)只显示音频和视频编解码器(audio and video codecs)，这不是您需要担心的事情，尤其是当媒体文件在Windows Media Player或电影和电视(Movies & TV)应用程序中播放正常时。
显示部分(Display)更有趣。您可以在此处找到有关显示器使用的分辨率以及用于连接显示器的图形适配器名称的信息。
其他子类别类似。您可以获得有关鼠标、键盘、红外输入设备（如果有）、硬盘驱动器、光驱、调制解调器（如果还有的话）、网络适配器(network adapter)等的完整详细信息。称为问题设备的部分与(Problem Devices)冲突(Conflicts)部分非常相似，因为Windows可以很好地处理硬件问题，并且该部分大部分时间都是空的。
如何使用系统信息(System Information)查看有关软件及其组件的详细信息
软件环境(Software Environment)部分在每台计算机上看起来都不同，因为在这里您可以看到有关已安装软件的所有详细信息，包括操作系统(operating system)附带的内容和添加的内容。与硬件(Hardware)部分一样，这些信息中的大部分仅对高级用户或 IT 专业人员感兴趣，其中一些类别是大多数人已经知道的程序组、启动程序、打印作业和运行任务等内容。尽管如此，将所有这些信息集中在一个地方还是很有用的。
一个有趣的地方是启动程序(Startup Programs)子部分。您可以检查它以确保仅在Windows 启动(Startup)时启动您真正需要的程序。
为什么需要检查系统信息(System Information)？
确实，您看到的很多内容乍一看可能意义不大，但系统信息(System Information)是了解Windows 计算机(Windows computer)上的内容的好方法。与其他一些管理应用程序可能发生的情况不同，您不能通过在System Information中四处浏览而使您的计算机处于任何危险之中，因为它只是信息的查看器。您可以使用系统信息(System Information)工具快速了解许多有用的信息，例如您的IP 地址(IP address)、正在运行的任务及其详细信息、启动时运行的程序、有关您的网络适配器(network adapter)的详细信息，或者您拥有的显卡和驱动程序为它安装。
您在系统信息中发现了哪些关于您的计算机的信息(System Information)？
有不少网站提供附加的“系统信息(system information)”工具，但我们看到的网站很少提供比内置系统信息(System Information)更多的功能。您是否使用过系统信息？(System Information?) 有(Was)没有你不明白的部分？有没有你觉得特别有用的部分——或者太神秘而根本没有任何用处？在下面发表评论，让我们讨论。
How to see details about your PC's hardware and software, using System Information
Windows has alwaуs been able to tеll you nearly everything you want to know aboυt your computer: hardware, ѕoftware, drivers, you name it. System Information puts all the information neatly at your fingertips. Let's take a look at this useful Windows app and what it can show you about your computer, in all modern versions of Windows:
NOTE: This guide applies to Windows 10, Windows 8.1 and Windows 7.
How to open System Information
In any modern version of Windows, you can use the search function to find and open the System Information app. Use the search terms "system information" or msinfo32 and click/tap on the result with the same name.
For a complete guide on all methods to open System Information see 10 ways to start System Information in Windows (all versions).
What is inside the System Information
When System Information opens you see a summary of your system that includes things like the OS Name, Version, System Name, System Manufacturer, and so on. If you read the summary, you understand the basics about your Windows computer or device. On the left, there are several categories. Each category in the left pane has expanded details on the right. The main categories are Hardware Resources, Components, and Software Environment.
To expand a category and see its details, double-click or double-tap on its name. You then see several subcategories. Clicking on their names loads useful information on the right side of the app window.
How to use the Search feature to find the information you want, inside System Information
At the bottom of System Information, there is a Find what box, where you can search for specific information. If the box is not displayed, select "Hide Find" in the Edit menu or press CTRL + F on your keyboard. You can hide it again using the same procedure. You can also hide the search box by pressing the Close Find button.
For example, if you wanted to find your computer's IP (internet protocol) address, you would type IP Address into the box and click/tap Find. In this particular case, you may need to press Find Next a few times until the active network connection is found.
Try the search feature using the keywords that you want, to see how it works.
How to see details about hardware, using System Information
The Hardware Resources category is full of technical details. It is primarily designed for expert users or IT professionals. The average user may not find anything useful without looking up exactly what the technical terms mean.
There is a section called Conflicts/Sharing that might or might not contain anything, depending on how your system is set up. In the DOS days and the early days of Windows, IRQ ("interrupt request") conflicts were a big deal and often you would have to twiddle and fiddle and shift things around so that your devices would not be fighting each other for the same resources. That is not a problem anymore, so the Conflicts/Sharing section is just for information, not a warning of problems.
If you want to find out more about what IRQs are assigned, click or tap on the IRQs section.
The Components section in System Information goes into detail about the hardware devices installed on your system. On our computer, Multimedia only displays the audio and video codecs, which is not something you need to worry about, especially if media files play fine in Windows Media Player or the Movies & TV app.
The Display section is more interesting. Here you can find information about the resolution used on your display and the name of the graphics adapter used to connect to it.
The other subcategories are similar. You can get full details about your mouse, keyboard, infrared input devices (if any), hard drives, optical drives, modem (if you still have one), network adapter and so forth. The section called Problem Devices is much like the Conflicts section because Windows handles hardware problems well and the section is empty most of the time.
How to see details about the software and its components, using System Information
The Software Environment section looks different on every computer, because this is where you see all the details about the software that you have installed, both what came with the operating system and what you have added on. As with the Hardware section, much of this information is only of interest to advanced users or IT professionals, and some of the categories are things like program groups, startup programs, print jobs, and running tasks, which most people already know about. Still, it is useful to have all this information in one place.
An interesting place is the Startup Programs sub-section. You can check it to make sure you start only the programs you truly need at the Windows Startup.
Why do you need to check System Information?
It is true that a lot of what you see might not mean much at first glance, but System Information is a good way to find out what is on your Windows computer. Unlike what can happen with some other administrative applications, you cannot put your computer in any danger by poking around in System Information, because it is just a viewer of information. You can use the System Information tool to quickly learn many useful things, like your IP address, the tasks that are running and their details, the programs that run at startup, details about your network adapter, or what video card you have and the driver installed for it.
What did you find out about your computer in System Information?
There are quite a few websites offering add-on "system information" tools, but few that we have seen offer much more than the built-in System Information. Have you used System Information? Was there any part of it you did not understand? Is there a section you found particularly useful - or too cryptic to be any use at all? Leave a comment below and let's discuss.
