The Start, or Modern, screen doesn’t have a taskbar, so when you run Modern apps you might lose track of which apps are running. There are a few ways to check which Modern apps are running and switch among all running apps.

“开始”或“现代”屏幕没有任务栏，因此在运行“现代”应用程序时，您可能会失去对正在运行的应用程序的跟踪。 有几种方法可以检查正在运行的Modern应用程序并在所有正在运行的应用程序之间切换。

One way of seeing which Modern apps are running is to press Alt + Tab. A dialog displays showing thumbnails of all apps running from the Modern screen. As long as you hold down Alt + Tab, the dialog stays on the screen. To cycle through the open apps, hold down the Alt key and press the Tab key. Each time you press the Tab key, the next app is selected on the dialog. When you get to the app to which you want to switch, release both keys.

查看正在运行哪些现代应用程序的一种方法是按Alt + Tab。 将显示一个对话框，显示从Modern屏幕运行的所有应用程序的缩略图。 只要按住Alt + Tab键，对话框就会保留在屏幕上。 要循环浏览打开的应用程序，请按住Alt键并按Tab键。 每次按Tab键，都会在对话框中选择下一个应用程序。 转到要切换到的应用程序时，松开两个键。

NOTE: On a touch screen, swiping repeatedly from the left cycles through running Modern apps.

注意：在触摸屏上，通过运行现代应用程序从左侧循环反复滑动。

You can also move the mouse to the extreme, upper, left corner of the Start screen. A thumbnail of the last active Modern app displays. Click on it to activate that app.

您也可以将鼠标移到“开始”屏幕的左上角。 显示最后一个活动的Modern应用程序的缩略图。 单击它以激活该应用程序。

Notice that there are partial outlines of boxes below the thumbnail. If you move your mouse down to those boxes, a sidebar displays thumbnails of the open Modern apps. Click a thumbnail to activate that app.

请注意，缩略图下方的框有部分轮廓。 如果将鼠标移到那些框，则侧边栏将显示打开的Modern应用程序的缩略图。 单击缩略图以激活该应用。

This sidebar also displays on the Desktop.

此侧栏也会显示在桌面上。

Clicking the Start button at the bottom of the sidebar also seems to take you to the last active app, unless you are on the Desktop. In that case, it takes you to the Start screen.

单击侧边栏底部的“开始”按钮似乎也将您带到上一个活动的应用程序，除非您位于台式机上。 在这种情况下，它将带您进入“开始”屏幕。

You can also simply launch a Modern app again to activate it. If the app is already running, it will become active. To toggle between the Start screen and the last Modern app you ran, press the Windows key.

您也可以再次启动Modern应用程序以将其激活。 如果该应用程序已经在运行，它将变为活动状态。 要在“开始”屏幕和您运行的最后一个Modern应用程序之间切换，请按Windows键。
