Windows自带截图

按【Windows】+【Shift】+【S】键，屏幕会出现图标，可以矩形、任意形状截图，窗口截图或者全屏截图，图像保存在剪贴板，这个方法可以灵活选择截图区域.

Press [Windows]+[Shift]+[S] keys, and the icon will appear on the screen. You can take a screenshot of rectangle, arbitrary shape, window or full screen, and save the image in the clipboard. This method is flexible in selecting the screenshot area, and I use it frequently.
