在Windows 8中，当您关闭计算机时，您实际上是在默认执行混合关闭。什么是混合关机？您可能听说过，Windows 8的启动速度比Windows 7 和以前版本的Windows快得多。

这是因为它关闭的方式。Windows 8不是执行冷启动，即必须加载所有内容，即操作系统内核^{(OS kernel)}、应用程序等，而是执行部分休眠，其中内核会话和设备驱动程序^{(Kernel session and device drivers)}保存到磁盘。

当您启动 Windows 8 时，它会从该休眠文件^{(hibernation file)}加载，这使启动时间^{(boot time)}更快。

在以前的Windows版本中，休眠文件^{(hibernation file)}要大得多，因为除了内核和设备驱动程序^{(kernel and device drivers)}之外，所有应用程序数据也都存储在该文件中。现在文件更小，加载时间更好。

此功能在Windows 8中称为^{(Windows 8)}快速启动^{(Fast Startup)}，默认情况下已启用。您可以通过转到控制面板中的电源选项^{(Power Options)}并单击左窗格中的选择电源按钮的功能来检查这一点。^{(Choose what the power button does )}

向下滚动^(Scroll)，您应该会看到一个选中的框，上面写着Turn on fast startup (recommended)。请注意，如果您根本没有列出启用^(Turn)快速启动复选框^{(startup checkbox)}，那是因为未启用休眠。

要在Windows 8^{(Windows 8)}中启用休眠，请打开提升的命令提示符并键入^{(command prompt and type)}以下行：

powercfg /hibernate on

现在，当您转到Power Options时，您应该会看到该框可见并已选中。那么如何在Windows 8^{(Windows 8)}中执行完全关闭？有三种方式。

1.您可以从电源选项^{(Power Options)}禁用快速启动或

2. 您可以简单地执行重新启动而不是关机。

3. 您可以在命令提示符^{(command prompt)}下使用以下命令：

shutdown /s /full / t 0

尽管看起来很奇怪，但重新启动Windows 8将首先执行完全关机，然后是冷启动。因此，这些是您可以完全关闭Windows 8的不同方法，如果您最近安装了新硬件等，这会派上用场。

此外，如果您不知道如何真正关闭Windows 8 PC，您需要将鼠标移到右上角或右下角。这将调出魅力栏^{(Charms Bar)}。

然后点击设置^(Settings)，然后点击电源^(Power)。最后，从列表中单击关闭。^{(Shut down)}

关闭Windows 8^{(Windows 8)} PC是一个相当复杂的过程，也是 Window 8 失败的众多原因之一。如果您有任何问题，请发表评论。享受！

How to Perform a Complete Shutdown in Windows 8

In Windows 8, when you shutdown your computer, you actually are performing a hybrid shutdown by default. What’s a hybrid shutdown? As you probably have heard, Windows 8 bоots up a lot faster than Windows 7 and previous versions of Windows.

This is because of the way it shuts down. Instead of performing a cold boot in which everything has to be loaded, i.e. the OS kernel, the apps, etc, Windows 8 performs a partial hibernation in which the Kernel session and device drivers are saved to disk.

When you startup Windows 8, it loads up from that hibernation file, which makes boot time much faster.

In previous versions of Windows, the hibernation file was much larger because in addition to the kernel and device drivers, all application data was also stored in the file. Now that the file is smaller, the load times are better.

This featured is called Fast Startup in Windows 8 and it is enabled by default. You can check this by going to Power Options in Control Panel and clicking on Choose what the power button does in the left pane.

Scroll down and you should see a box checked that says Turn on fast startup (recommended). Note that if you do not have the Turn on fast startup checkbox listed at all, it is because hibernation is not enabled.

To enable hibernation in Windows 8, open an elevated command prompt and type in the following line:

powercfg /hibernate on

Now when you go to Power Options, you should see the box is visible and checked. So how to perform a full complete shutdown in Windows 8? There are three ways.

1. You can either disable fast startup from Power Options or

2. You can simply perform a restart instead of a shutdown.

3. You can use the following command at the command prompt:

shutdown /s /full / t 0

As odd as it may seem, restarting Windows 8 will first perform a complete shutdown followed by a cold boot. So those are the different ways you can perform a full shutdown of Windows 8, which comes in handy if you recently installed a new piece of hardware, etc.

Also, just in case you don’t know how to actually shutdown a Windows 8 PC, you need to move your mouse up to the top right or bottom right corner. This will bring up the Charms Bar.

Then click on Settings and then Power. Finally, click on Shut down from the list.

It’s quite a process to shutdown a Windows 8 PC and one of the many reasons Window 8 failed. If you have any questions, post a comment. Enjoy!
