Windows 8应用程序是在Windows 8中以(Windows 8)全屏模式(screen mode)运行的应用程序。它们可以提供基本功能和高级功能，具体取决于它们的设计方式。但是，至少到目前为止，它们提供的基本功能就像您在iOS 或 Android 平板电脑(iOS or Android tablet)上使用的应用程序一样。虽然在移动设备上使用它们感觉舒适和熟悉，但将它们包含在桌面操作系统中会让许多用户感到震惊。它们占据了整个屏幕，无需离开您的任务栏(task bar)或包括 Windows 用户所期望的最小化、最大化或关闭按钮。虽然这对于初学者来说会很刺耳，但它们确实很容易使用并且很有趣。如果你发现自己对这种新形式的Windows 应用程序(Windows application)，继续阅读您在Windows 8 应用程序(Apps)中使用所需的所有提示。
如何启动 Windows 8 应用程序
为了开始，您需要找到一个应用程序并启动(app and launch)它。这可以从Windows 8的新开始(Start)屏幕完成。要到达那里，请将光标悬停在屏幕的左下角，直到出现“开始(Start)”屏幕的小缩略图。单击(Click)或点击缩略图以打开真实的东西。或者，您可以按键盘上的Windows键。
启动(Start)“开始”屏幕后，您将看到已安装在计算机上的每个应用程序的磁贴。有些图块只是显示一个名称；其他，称为动态磁贴，显示来自应用程序的数据。
单击(Click)或点击磁贴以启动您选择的应用程序(chosen app)。
要了解有关Windows 8中磁贴的更多信息，请立即阅读本教程：Windows 8简介：什么是磁(Tiles)贴？。
如何访问应用程序的上下文菜单
使用 Windows 8 应用程序时，您会发现它们通常包含非常简单的界面。它们没有典型桌面(Desktop)应用程序的按钮和菜单。要访问应用程序的其他功能，请右键单击其应用程序窗口中的任意位置或从屏幕顶部或底部滑动。(application window or swipe)
在示例中，捆绑的Weather 应用程序(Weather app)的菜单允许您刷新屏幕、从华氏(Fahrenheit)温度更改为摄氏温度(Celsius)以及更改您的天气位置(weather location)。其他应用程序将具有不同的功能，因此这始终是了解新应用程序的第一步。
如何访问应用程序的魅力
在标准应用程序中，如果您想更改任何设置，您将直接进入工具栏。正如您开始了解的那样，Windows 8 应用程序没有工具栏。要更改设置，您需要使用Charms。要了解有关它们的更多信息，我们发布了此详细教程：介绍 Windows 8：什么是魅力(Charms)？。
要前往那里，请将光标移动到屏幕的右下角（或右上角），直到一系列图标从显示屏一侧延伸出来。向上（或向下）滑动以激活Charms，然后单击或点击“设置”。("Settings.")
这将打开可用于更改设置的链接列表。您将在此处将帐户添加到您的邮件应用程序(Mail App)、更改日历应用程序(Calendar app)中的选项(Options)以及更改必应应用程序(Bing app)中的隐私设置。您的应用程序的所有可配置选项都可以通过此菜单访问。
同样，您可以使用“分享(Share)”魅力通过电子邮件或社交网络与他人分享应用程序中的内容(share content)。设备(Devices)魅力可用于与计算机上的设备（如打印机）进行交互，并打印应用程序中的内容。
如何在(Search Within)Windows 8 应用程序(App)中搜索
例如，在使用Wikipedia(Wikipedia)等应用程序时，您会发现您期望的搜索栏(search bar)不会位于应用程序的主窗口中。在您习惯Windows 8的Charms中集成的搜索功能(search feature)之前，这可能看起来很奇怪。您用于查找文件、文件夹或应用程序(folder or application)的相同搜索工具(search tool)也可以在您的应用程序中进行搜索。
要使用它，请将光标悬停在屏幕的右下角并向上滑动。单击(Click)或点击“搜索”。("Search.")在提供的字段(field and press) 中输入您的搜索词，然后按Enter查看结果。
某些应用程序，包括Windows 8 应用商店(Store)，允许您通过刚开始输入来进行搜索。搜索工具(search tool)将自动打开以接受您的输入。
如何在 Windows 8(Between Windows 8) 应用程序之间切换(Apps)
尽管应用程序使用起来很有趣，但您最终会想要改变焦点并开始做其他事情。如果没有standard maximize/minimize按钮或任务栏，您可能会不知所措。
您的第一个选项是单击或点击左下角以返回“开始(Start)”屏幕。您的应用程序将滑入后台并进入待机模式，以使用更少的系统资源。从开始(Start)屏幕，您可以打开另一个应用程序或切换到桌面(Desktop)。
您的下一个选择是切换回您关注的最后一个屏幕。为此，只需将鼠标悬停在屏幕的左上角，直到打开缩略图。单击(Click)或点击缩略图以重新打开该窗口。
如果您想切换到另一个打开的应用程序，请将光标移动到屏幕的左上角并向下滑动以打开各种应用程序切换器(app switcher)。这是一个菜单，显示所有打开的应用程序、桌面(Desktop)和开始(Start)屏幕的图标。通过触摸，这是通过在左侧滑入和滑出来实现的。
如果要使用键盘启动它，请按Windows + D。然后，单击或点击您要选择的应用程序，一切顺利。
最后但同样重要的是，旧的ALT + TAB 键盘快捷键(keyboard shortcut)在Windows 8中同样有效。
如何关闭 Windows 8 应用程序
当您使用完一个应用程序后，您可以简单地从它切换到后台并将其发送到后台。虽然它消耗最少的系统资源，但它会弄乱您的切换器菜单(switcher menu)。为了保持井井有条或防止在旧系统上丢失资源，您可以选择永久关闭您的应用程序。要关闭活动的应用程序(App)，请将光标移动到窗口顶部。当它变成一只手时，单击或点击(click or tap)并按住以抓住应用程序，将其拖到屏幕底部并释放(screen and release)它。
要关闭不活动的应用程序，请激活切换器，右键单击或长按应用程序缩略图，然后单击(thumbnail and click)或点击“关闭”。("Close.")
显然，您也可以从任务管理器中关闭(Task Manager)Windows 8。
如何将Windows 8 应用程序(App)捕捉到屏幕一侧
Windows 8应用程序的主要缺点之一是缺乏在同一屏幕上运行多个应用程序的灵活性，就像在桌面(Desktop)上一样。在标准实践中，单个应用程序会占据全屏并且无法调整大小。但是，如果您有一台分辨率大于 1366x768 的显示器，您可以将应用程序捕捉到屏幕一侧并在其旁边运行一秒钟。(However, if you have a monitor with a resolution greater than 1366x768, you have the ability to snap an app to the side of the screen and run a second next to it.)
要捕捉应用程序，您需要将其打开但不处于活动状态。访问切换器，然后单击(switcher and click)或点击并按住(tap and hold)要捕捉的应用程序。将光标拖出切换器并将鼠标悬停(switcher and hover)在屏幕的左侧或右侧，直到出现一个中间有三个点的栏。
释放以捕捉应用程序，当您在可用屏幕空间的较大部分中切换其他应用程序时，这将使其在屏幕一侧保持活动状态。每个应用程序在快照模式下都有各种功能，因此请尝试一下。更有用的应用程序之一是邮件(Mail)，因为它可以让您在浏览或工作时密切关注您的收件箱。
此外，您可能希望在浏览网页或工作时保持“音乐”应用程序的打开状态。(Music app)
结束的想法
虽然应用程序需要一段时间才能适应，但它们无疑是Windows 8令人兴奋的新功能。您会发现许多有用的示例可供试用，这些示例与Windows 8捆绑在一起，包括Mail、People、Calendar、Weather 和 News(Weather and News)。您甚至可以访问商店，在那里您可以查找和下载更多应用程序。尽管与Android Market 或 Apple(Android Market or Apple)的App Store相比，目前可用的(App Store)Windows 8应用程序选择相形见绌，但随着Windows 8的普及，这些应用程序肯定会扩大。

Introducing Windows 8: 7 Tips for Working with Apps
Windows 8 apps are applications that rυn in full screen mode in Windows 8. They can provide both basic and advanced functionality, depending on how they were designed. But, at least ѕo far, they provide basic functionality just like apps you'd use оn your iOS or Android tablet. While using them on a mоbile device feels comfortable and familiar, their inclusion on the desktop OS will be a bit of a shock to many users. They take up the whole screen without leaving your task bar or including the minimize, maximіze or close buttons Windows users cоme to expect. While this will be jarring for first timers, theу really are simple to work with and can be a lot of fun. If you find уourself baffled by this new form of Windows apрlicаtion, read on for all the tips you'll neеd for getting around in Windows 8 Apps.
How to Launch Windows 8 Apps
In order to get started you'll need to find an app and launch it. This can be done from Windows 8's new Start screen. To get there, hover your cursor over the bottom-left corner of the screen until a small thumbnail of the Start screen appears. Click or tap the thumbnail to open the real thing. Alternatively, you can press the Windows key on your keyboard.
Once the Start screen launches you'll see tiles for each of the apps you have installed on your computer. Some tiles simply display a name; others, known as live tiles, display data from the app.
Click or tap a tile to launch your chosen app.
To learn more about tiles in Windows 8, don't hesitate to read this tutorial: Introducing Windows 8: What are the Tiles?.
How to Access an App's Context Menu
When working with your Windows 8 apps you'll find that they typically contain very simple interfaces. They don't have the buttons and menus of a typical Desktop application. To access additional features of the app, right-click anywhere in its application window or swipe from the top or the bottom of the screen.
In the example, the bundled Weather app's menu allows you to refresh the screen, change from Fahrenheit to Celsius and change your weather location. Other apps will have different functions so this is always a great first step when getting to know a new app.
How to Access the Charms for an App
In a standard application you'd go straight to the toolbar if you wanted to change any settings. As you're beginning to understand, Windows 8 apps don't have toolbars. To change settings, you'll need to use the Charms. To learn more about them, we published this detailed tutorial: Introducing Windows 8: What are the Charms?.
To go there, move your cursor to the bottom-right (or top-right) corner of the screen until a series of icons extend from the side of your display. Slide up (or down) to activate the Charms and click or tap "Settings."
This will open a list of links you can use to change settings. You'll go here to add accounts to your Mail App, change your Options in your Calendar app and to change your privacy settings in the Bing app. All of your app's configurable options will be accessibly through this menu.
Similarly, you can use the Share charm to share content from the app with others, via email or social networks. The Devices charm can be used to interact with devices on your computer, like your printer and have content from the app printed.
How to Search Within a Windows 8 App
While using apps such as Wikipedia, for example, you'll find that the search bar you expect won't be located in the main window of the app. This may seem weird until you get used to Windows 8's integrated search feature in the Charms. The same search tool you'll use to find a file, folder or application can also search within your app.
To use it, hover your cursor over the bottom-right corner of the screen and slide up. Click or tap "Search." Type your search term in the provided field and press Enter to view your results.
Some apps, including the Windows 8 Store, allow you to search by just starting to type. The search tool will automatically open to accept your input.
How to Switch Between Windows 8 Apps
As fun as apps can be to use, you'll eventually want to change focus and start doing something else. Without the standard maximize/minimize buttons or taskbar you may be at a loss for how to go about it.
Your first option is to click or tap the bottom-left corner to return to the Start screen. Your app will slide into the background and go into a standby mode, to use less system resources. From the Start screen you can open up another app or switch to the Desktop.
Your next option is to switch back to the last screen you had in focus. To do this, simply hover your mouse over the top-left corner of the screen until a thumbnail opens up. Click or tap the thumbnail to reopen that window.
If you'd like to switch to another of your open apps, move your cursor to the top-left corner of the screen and slide down to open an app switcher of sorts. This is a menu that shows icons for all of your open apps, the Desktop and the Start screen. With touch, this is achieved with a swipe in and out on the left.
If you want to use the keyboard to launch it, press Windows + D. Then, click or tap the app you want to select and you're good to go.
Last but not least, the old ALT + TAB keyboard shortcut is working just as well in Windows 8.
How to Close a Windows 8 App
When you're done working with an app you can simply switch away from it and send it into the background. While it consumes minimal system resources, it will clutter up your switcher menu. To stay organized or to prevent lost resources on an older system you have the option of closing your apps for good. To close an active App, move your cursor to the top of the window. When it changes to a hand, click or tap and hold to grab the app, drag it to the bottom of the screen and release it.
To close an inactive app, activate the switcher, right-click or long-press the app thumbnail and click or tap "Close."
Obviously, you can close a Windows 8 also from the Task Manager.
How to Snap a Windows 8 App to the Side of the Screen
One of the major downfalls of Windows 8 apps is the lack of flexibility to run multiple apps on the same screen as you can on the Desktop. In standard practice, the single app takes up the full screen and can't be resized. However, if you have a monitor with a resolution greater than 1366x768, you have the ability to snap an app to the side of the screen and run a second next to it.
To snap an app, you'll need to have it open but not active. Access the switcher and click or tap and hold on the app you want to snap. Drag your cursor out of the switcher and hover over the left or right side of the screen until a bar with three dots in the middle appears.
Release to snap the app, which will keep it active on the side of your screen as you switch through other apps in the larger portion of the available screen space. Each app has various functions in snapped mode, so try them out. One of the more useful apps to snap is Mail, as it lets you keep an eye on your inbox while you browse or work.
Also, you might want to keep the Music app opened while you browse the web or do your work.
Closing Thoughts
While apps will take awhile to get used to, they are undoubtedly an exciting new feature of Windows 8. You'll find a bevy of useful examples to try out, bundled with Windows 8 including Mail, People, Calendar, Weather and News. You'll even have access to the Store, where you can go to find and download more apps. Though the selection of Windows 8 apps available at the moment pales in comparison to the Android Market or Apple's App Store, the offerings are sure to expand as Windows 8 gains popularity.
