按下PrtSc键之后，系统看似没有任何反应，但系统早已在你按下该键的同时把整个屏幕的内容以图形的形式保存在内存中了，你只要打开一个图像编辑软件（如Windows自带的“画图”软件、Office）或者微信、QQ等的对话窗口，按下键盘快捷键“Ctrl+V”就能将画面粘贴下来。

注意事项和小问题
如果多次按下PrtSc键，电脑默认剪贴板上复制的是你最后一次按下时的屏幕截图。如果需要连续截图，那么也很简单。按住win不放，再在几个页面按下PrtSc就可以多次截图。同理这时候在其他界面上粘贴时，就会一次性将多张截图同时粘贴。
笔记本电脑按PrtSc键无效，那么一般是因为公用键问题。简单来说就是，PrtSc这个按键上同时有F11的标志，说明台式的不同两个按键在笔记本上是合二为一的。通过笔记本最下方一排的Fn按键可以进行键盘功能的转换，Fn旁的小灯亮起时，一般是操控F+数字的功能，这时候再按PrtSc自然就没有截图效果啦。

快捷键是win+shift+S，按下之后会出现下图这样的界面：

可以看到，屏幕整体变暗，上方有四个选项，分别是：矩形截图；任意形状截图；全屏截图；取消。当选中所需区域后，截图就会保存于剪贴板，可以粘贴到文档或社交软件等等地方。
