在Windows 10中，您可以打开同一应用程序(app and work)的多个窗口并同时使用它们。无论您是比较信息、将文件从一个位置传输到另一个位置，还是为您的家庭作业或(homework or report)Microsoft Word 或 Excel(Microsoft Word or Excel)报告从多个文档中编译数据，运行同一应用程序的多个实例都可以显着提高工作效率。如果您想了解如何在 Windows 10 上两次打开同一应用程序(Windows 10)或(app twice)如何打开同一应用程序的多个窗口，本教程提供了几个答案：
注意：我们使用(NOTE:)Windows 10 November 2019 Update创建了本教程，但提供的功能也适用于其他版本的Windows 10以及Windows 7和Windows 8。
首先(First)要做的事情：哪些应用程序支持多个(support multiple)窗口？
一些应用程序被开发为在多个实例中运行，而另一些则被设计为仅限于一个窗口。在Windows 10(Windows 10)中有大量可以同时运行多个实例的应用程序。Google Chrome 或 Mozilla Firefox(Google Chrome or Mozilla Firefox)等浏览器以及Word 或 Excel(Word or Excel)等Microsoft Office应用程序支持多个(support multiple)窗口。大多数Windows桌面应用程序也是如此。
但是，来自Microsoft Store的现代应用程序（包括Microsoft Store本身）无法在Windows 10中打开更多实例。要了解有关这两种应用程序之间差异的更多信息，请阅读什么是Windows 应用程序(Windows app)？什么是桌面应用程序？他们有什么不同？
其他仅限于一个窗口的应用程序包括Windows Media Player、OneDrive、Dropbox、大多数Windows游戏、防病毒应用程序(antivirus apps)和Skype。
简而言之，除了少数例外，如果您没有从Microsoft Store下载它，您应该可以同时打开该应用的多个窗口。但是，可以肯定的是，请继续阅读并尝试一下！
在Windows(Windows)中打开应用程序的多个实例的经典方法
打开已经运行的应用程序的另一个窗口的最直观的方法是再次启动它。虽然单击或点击应用程序的任务栏快捷方式仅提供对其活动窗口的访问权限，但您可以使用桌面或“开始”菜单(Start Menu)中可用的同一应用程序的任何其他快捷方式再次运行它。您甚至可以在任务栏的搜索字段(search field)中输入应用程序的名称并从那里打开它。
或者，右键单击（或在触摸屏设备上按住）任何打开的应用程序的任务栏图标(taskbar icon)。然后，在上下文菜单中，单击或点击(click or tap)应用程序的名称以启动它的另一个实例。
Shift + Click打开应用程序的多个实例
您可以使用多种快捷方式打开应用程序的多个实例，最流行的是Shift + Click或Shift + Tap用于触摸屏。
首先，打开要在多个实例中运行的应用程序。然后，按住键盘上的Shift键并用光标单击(keyboard and click)- 或用手指点击 - 其任务栏图标(taskbar icon)。
单击或点击(click or tap)打开一个新实例，两次单击或点击打开两个，依此类推。
只要程序允许多个窗口，其他实例应该立即打开。
使用管理权限打开同一应用的多个实例
如果您需要打开同一个桌面应用程序(desktop app)的多个窗口，但具有管理权限，则要记住的键盘快捷键(keyboard shortcut)类似于第一个。您可以使用Ctrl + Shift + Click或Ctrl + Shift + Tap触摸屏。同时按住Ctrl和Shift键，然后单击或点击要在多个实例中以管理员身份运行的应用程序的任务栏图标。(taskbar icon)
这会触发UAC 提示(UAC prompt)，您必须在打开另一个应用程序实例之前确认您的选择。要了解有关以管理员身份运行应用程序的更多信息，请阅读在Windows 10中使用“以管理员身份(Windows 10)运行(Run)”的 13 种方法。
Ctrl + N启动同一应用程序的多个窗口
打开一个应用程序后，访问它，然后使用Ctrl + N快捷方式打开另一个新的应用程序窗口(application window)。只需(Just)按住Ctrl键并同时按键盘上的N。
此快捷方式适用于文件资源管理器(File Explorer)、Microsoft Office 系列(Microsoft Office family)中的程序（如Word 或 Excel(Word or Excel)）以及所有主流浏览器（如Google Chrome、Mozilla Firefox、Opera或Microsoft Edge）。
(Run)使用鼠标中键(mouse middle-click)运行应用程序的多个实例
如果您的 Windows 10计算机或设备(computer or device)上有鼠标，则可以使用其滚轮(scroll wheel)打开应用程序的多个窗口。打开应用程序的一个实例，然后在任务栏中单击其图标以启动另一个窗口。每次您中间单击应用程序的任务栏图标(taskbar icon)时，都会打开同一程序的另一个窗口。将光标悬停在应用程序的图标上会显示其所有打开窗口的预览，让您选择所需的窗口。
提示：(TIP:)如果您使用的是触摸板，可以按照本教程中的说明将其配置为中键：如何在Windows 10中配置您的触摸板。
Windows + Shift + 1 到 9打开同一应用程序的多个窗口
如果您喜欢键盘快捷键，Windows + Shift + 1 to 9是另一种可以打开同一应用程序的多个实例的快捷键。首先，启动程序。无论您从哪里运行它，它的图标都应该在任务栏中可见。从左到右计算任务栏上的图标，并记住您想要更多打开副本的应用程序的数量。(Count)在下图中， 1 对应于File Explorer， 2 对应于Mozilla Firefox，依此类推。
按住键盘上的Windows和Shift键，然后按(keyboard and press)与要在附加窗口中运行的打开应用程序图标对应的数字键。我们使用Windows + Shift + 1启动另一个文件资源管理器(File Explorer)实例，Windows + Shift + 2用于 Mozilla Firefox，Windows + Shift + 5用于 Microsoft Edge，Windows + Shift + 7用于打开多个Google Chrome实例。
如果您想打开一个没有任务栏快捷方式(taskbar shortcut)的应用程序的多个窗口，请记住，与其任务栏图标(taskbar icon)关联的数字可能会因您当时打开的其他应用程序而异。要有效地使用此方法并避免混淆，您可以将应用的快捷方式固定到任务栏。
您需要在多个实例中运行哪个应用程序？
在编写教程时，我们经常编辑文本、进行研究和移动文件。这意味着我们经常需要文件资源管理器(File Explorer)、Microsoft Word和不同网络浏览器的多个实例。我们还以分屏模式并排使用这些应用程序以提高工作效率。你呢？您要多次打开哪些应用程序？在评论部分(comment section)让我们知道。
How to open multiple windows of the same app in Windows 10
In Windows 10, you can open multiple windows of the same app and work with them in parallel. Whether you're comparing infоrmation, transferring files from one location to another, or compiling datа from seνeral documents for your homework or report in Microsoft Word or Excel, running multiple instances of the same aрp can рrovide a significаnt boost in productivity. If you want to find out how to oрen the same app twice on Windows 10 or how to оpen multiple windows of the same app, thiѕ tutorіal provides seνeral answers:
NOTE: We created this tutorial using Windows 10 November 2019 Update, but the features presented also work on other versions of Windows 10, as well as in Windows 7 and Windows 8.
First things first: Which apps support multiple windows?
Some apps are developed to run in multiple instances, while others are limited to only one window by design. There are plenty of apps that can run multiple instances at the same time in Windows 10. Browsers, like Google Chrome or Mozilla Firefox, and Microsoft Office apps, like Word or Excel, support multiple windows. So do most desktop apps for Windows.
However, modern apps from the Microsoft Store, including the Store itself, can't have more instances open in Windows 10. To learn more about the differences between the two types of apps, read What is a Windows app? What is a desktop application? How are they different?.
Other apps limited to one window are Windows Media Player, OneDrive, Dropbox, most games for Windows, antivirus apps, and Skype.
In short, with a few exceptions, if you didn't download it from the Microsoft Store, you should be able to have multiple windows of the app open at the same time. But, just to be sure, keep on reading and give it a try!
The classic way to open multiple instances of an app in Windows
The most intuitive way to open another window of an app that's already running is to launch it once more. While clicking or tapping on an app's taskbar shortcut only provides access to its active window, you can use any other shortcut for the same app available on your desktop or in the Start Menu to run it again. You can even type the app's name in your taskbar's search field and open it from there.
Alternatively, right-click (or press-and-hold, on touch-screen devices) on any open app's taskbar icon. Then, in the contextual menu, click or tap on the app's name to launch another instance of it.
Open multiple instances of an app using Shift + Click
There are several shortcuts you can use to open multiple instances of an app, the most popular being Shift + Click or Shift + Tap for touch screens.
First, open the application you want to run in multiple instances. Then, hold down the Shift key on your keyboard and click with your cursor - or tap with your finger - on its taskbar icon.
One click or tap opens a new instance, two clicks or taps open two, and so on.
As long as the program allows multiple windows, other instances should immediately open.
Open multiple instances of the same app with administrative permissions
In case you need to open multiple windows of the same desktop app, but with administrative permissions, the keyboard shortcut to remember is similar to the first one. You can use Ctrl + Shift + Click or Ctrl + Shift + Tap for touch screens. Press and hold the Ctrl and Shift keys simultaneously, and then click or tap on the taskbar icon of the app that you want to run as admin in multiple instances.
This triggers a UAC prompt, and you must confirm your choice before another instance of the app is opened. To learn more about running apps as administrator, read 13 ways to use "Run as administrator" in Windows 10.
Launch multiple windows of the same app using Ctrl + N
After opening an app, access it, and use the Ctrl + N shortcut to open another new application window. Just hold down the Ctrl key and press N on your keyboard at the same time.
This shortcut works with File Explorer, programs in the Microsoft Office family, like Word or Excel, and every major browser, such as Google Chrome, Mozilla Firefox, Opera, or Microsoft Edge.
Run multiple instances of an app using the mouse middle-click
If you have a mouse on your Windows 10 computer or device, you can use its scroll wheel to open multiple windows of an app. Open one instance of an application, then middle-click on its icon from the taskbar to launch one more window. Another window of the same program opens every time you middle-click the app's taskbar icon. Hovering your cursor over an app's icon shows a preview of all its open windows, letting you choose the one you need.
TIP: If you're using a touchpad, it is possible to configure it for middle-click by following the instructions in this tutorial: How to configure your touchpad in Windows 10.
Open multiple windows of the same app with Windows + Shift + 1 to 9
If you like keyboard shortcuts, Windows + Shift + 1 to 9 is another one that can open multiple instances of the same app. To begin, launch the program. No matter where you run it from, its icon should be visible in the taskbar. Count the icons on the taskbar from left to right and remember the number of the app you want to have more open copies of. In the image below, 1 corresponds with File Explorer, 2 with Mozilla Firefox, and so on.
Hold down Windows and Shift on your keyboard and press the number key corresponding to the icon of the open app you want to run in an additional window. We used Windows + Shift + 1 to launch another instance of File Explorer, Windows + Shift + 2 for Mozilla Firefox, Windows + Shift + 5 for Microsoft Edge, and Windows + Shift + 7 to open multiple instances of Google Chrome.
If you want to open multiple windows of an app that doesn't have a taskbar shortcut, keep in mind that the number associated with its taskbar icon may vary depending on what other apps you have open at the time. To use this method efficiently and avoid confusion, you can pin your app's shortcut to the taskbar.
Which app do you need to run in multiple instances?
We edit texts, do research, and move files around a lot when we write our tutorials. That means we regularly need multiple instances of File Explorer, Microsoft Word, and different web browsers. We also use these apps in split-screen mode, side by side for increased productivity. What about you? What apps are you trying to open multiple times? Let us know in the comment section.
