Win8, the secret of the speed improvement of the switch machine is faster than Win7.

After the installation of WIN8, many people have experienced the amazing speed of its switch machine, especially the boot speed, compared to Win7, it promoted more than 1:30 point. In some ultra-extreme and SSD-equipped machines, the speed of the switch can be within a few seconds. For example, Surface Pro, its measured system boot speed of 2 seconds, from boot to automatic login to the start screen only 6 seconds.

What technology has improved the speed of WIN8? If you want to generalize in the simplest words, it should be "system session hibernation" or, more simply, "hybrid shutdown."

In previous Windows OS, the typical shutdown sequence is:

1. Click "Shutdown".

2. Windows broadcasts Run application shutdown information so that applications can save data and settings. The application can also require some extra time to end its current work.

3. Windows closes a user session for each logged-on user.

4. Windows sends shutdown information to the service, notifies you that the shutdown has started, and then closes the service. If the service is not responding, the system forces the shutdown.

5. Windows broadcasts information to the device, signaling the device to close.

6. Windows shuts down system sessions (also known as "Session 0").

7. Windows refreshes the system drive pending data to ensure full storage.

8. Windows sends signals to the computer for power outages through the ACPI-bounded system.

Looking at the typical shutdown steps above, are you also thinking of some of the steps corresponding to the screen UI performance?

Let's look at the main steps of the hybrid shutdown that Windows 8 uses:

1. Click "Shutdown".

2. Windows broadcasts Run application shutdown information so that applications can save data and settings. The application can also request some extra time to end its current work.

3. Windows closes a user session for each logged-on user.

4. System session sleep, and power off.

Visible, Windows8 xitongtiandi.com closes only the user session and does not completely shut down the computer as before. At this point, Windows no longer waits for and ends system services and closes session 0, but lets it hibernate. The practice of shutting down user sessions + Hibernation system services and system sessions, known as "hybrid shutdown," is not difficult to understand.

Or a popular point, just like you before cleaning, you need to assemble a professional mop, assembled, before you can start cleaning. Now, you can pick up the mop and start cleaning, because the last time you cleaned it, you didn't remove the mop as usual.

On the structure is the shutdown of the reverse process, so with a hybrid shutdown, the start-up nature will soon. However, in addition to the RAID card, the general hard drive read faster than the write speed, plus the shutdown, the system will notify and wait for the application to exit, so from the senses, the boot process than the shutdown process appears to be faster.
