Brief introduction to Windows 7 start and stop

Before you start using Windows 7, it is important to have a more comprehensive understanding of the new Windows operating system. Whether it's a new feature or a feature improvement, Windows 7 has changed significantly compared to previous-generation operating systems. But for a computer beginner, a new understanding of Windows 7 is simpler. After you understand the design philosophy and some basic elements of Windows 7, it is more convenient to use Windows 7.

This article focuses on some basic essentials for installing Windows 7 computers, including a brief introduction to Windows 7, startup and shutdown of Windows 7 computers.

Introduction to Windows 7

When it comes to Windows 7, you have to say the first two generations of the very famous Windows operating system. In the 21st century, the most brilliant computer operating system is Windows XP, and is currently on the market the most commonly used operating system of computers. In 2007 Microsoft unveiled a new operating system, Windows Vista, which has changed dramatically compared to Windows XP. These changes are based on kernel upgrades, with better security and stability. And in the performance and design concepts more in line with the needs of modern computers, more suitable for the use of computer users.

Two years after Windows Vista was released, Microsoft again released a new operating system,--windows 7. Compared to Windows Vista,windows 7, it has become simpler, faster for users to complete their work, and has a better computer experience.

Start Windows 7

Before you know how to start Windows 7, you must first understand the startup process for your computer. Starting a computer is a very critical step, because if the computer doesn't start, then the strong computer is just a heap of scrap metal. So it is important to start the computer correctly.

The startup process of the computer

Computer startup is a very complex process, but since this process is basically done automatically by the computer, it is generally not necessary to know what the computer is doing in 1 minutes or so. But in order to better understand the launch of Windows 7, the author briefly explained the start of the computer process.

When the user presses the power button on the computer's host box, the computer's motherboard basic input and output system (BIOS) is powered up self-test (Power–on self test,post). The execution post is mainly to detect whether the key hardware device can work properly, such as CPU, display card, memory, hard disk and other devices. This step is usually very short.

After the power on Self-Test is complete, the motherboard BIOS will look for other critical device BIOS. The BIOS for the other device initializes the corresponding device, which displays information about the device on the monitor. After initialization, the CPU, memory and other devices are detected and the standard hardware devices installed by the system are detected, such as optical drives, hard drives, etc.

After the standard equipment is tested, the BIOS will output the information on the monitor, so that the user may know the relevant information about the computer hardware device. The BIOS then performs the final extended system Configuration data (Extended system Configuration DATA,ESCD), which is responsible for the startup of Windows 7 after the BIOS completes the ESCD by handing the execution authority to the Windows 7 boot manager.

The Windows 7 Boot manager reads the boot information from the BCD file to complete the startup of the operating system. If the computer is equipped with only one operating system, it will call the loader of the system directly to complete the system loading.

The loader then starts loading the system and loads the driver for the appropriate hardware. After completing this step, the user will be able to see the Windows 7 login interface.

In the login interface to select a user account, and enter a password, the computer will normally start. If there is only one user account in the system and the password is not set, it is logged in directly, as shown in the following illustration, a Windows 7 login welcome interface.

How to start your computer

Although the development of the computer industry, users need more ways to start the computer to meet the work, day-to-day needs. In order to better understand the startup of Windows, I think it is necessary to explain the relevant content of computer startup.

Hard drive boot: the most common way to boot is to boot the operating system from the hard drive, which is how most computers start. When a user installs a Windows operating system on a computer, it is generally used in this way to start the computer.

CD-ROM boot: Use this way to boot typically because the system in your computer is damaged, or you need to take some of the system's key files offline. This is usually the way to install the operating system for a newly assembled computer, and some systems can be run directly on the disc, which is very convenient.

U disk Startup: This way to start the general use of less, Windows 7 support using a U disk for installation. That is, just copy the files from the Windows 7 installation CD to a USB drive, and you can use a U disk to boot the operating system for your new computer, which is the advantage of not having to burn the disc. Note that the installation of a USB flash drive for Windows 7 requires a specific procedure to copy the files to a USB drive.

Network boot: Network startup is generally applicable to the server, the daily use of less office users. On the one hand, the technical threshold is relatively high, on the other hand, the need for dedicated network server support. Starting this way starts or checks the computer by using the network card directly to receive data on the Web server.

After solving the usual computer startup mode, users can start the computer in different ways depending on the computer environment and running state.

Startup of a multi-system coexistence computer

For a variety of reasons, it is possible for users to use Windows 7 while they want to use systems such as Windows Vista and Windows XP. The user can then build a multiple-system coexistence computer and select the operating system you want to use when the computer starts up. Because Windows Vista and Windows 7 are new systems based on NT6, the boot manager used by Windows XP is different. So when you start your computer, the NT6 boot Manager is loaded first, as shown in the following figure.

When Windows Startup Manager displays multiple system interfaces, an operating system is selected by default, and the selected operating system is automatically started after the user's selection time has ended. The default wait time is 30 seconds, and users can adjust to the system as needed. When the user uses the arrow keys to start the system selection, the wait time stops the countdown. When you select the operating system you want to start and click Enter on the keyboard, the computer automatically loads the system and completes the system startup, as shown in the following illustration of a Windows 7 startup interface.

Turn off Windows 7

Starting your computer correctly is no doubt an important step, and the proper shutdown of your computer is also a very important step. In Windows 7, the system allows users to customize how to set up a variety of ways to shut down a computer. and provides three energy-saving status as a choice to turn off the computer, users can choose according to their needs.
The Windows 7 shutdown process is simpler than the previous generation of windows and is faster on the shutdown speed. To help users understand the shutdown of Windows, the author briefly explains the shutdown process for Windows 7.

By clicking the Shutdown button, Windows 7 Winlogon.exe starts working to prepare for shutting down Windows.

Winlogon.exe sends shutdown commands to each process and monitors feedback for these processes.

When all processes are finished, Windows Session Manager ends the current session and displays the Windows security desktop.

In this step, Windows saves the user's document and logs out, and then completes Windows shutdown.

By completing the previous steps, Windows is completely closed. There is also a situation that will prevent Windows from shutting down by running programs that require a user to save, when Windows prompts the user whether to force the shutdown or cancel the shutdown, as shown in the following illustration.

Energy-saving state of the computer

In Windows 7, you can turn your computer into two energy-saving states in addition to the normal shutdown of your computer. Use these two energy-saving states to help users quickly shut down and restore the state of your computer.

Sleep: Sleep is an energy-saving state that starts with Windows Vista, which shuts down the computer in seconds and allows the computer to continue powering the physical memory by converting the computer to sleep. The window that the current user opens, ie browser, etc. will be saved. When you need to restore, click the left mouse button, the computer will be completed in a few seconds to start. And after the computer is started, the windows and programs before the shutdown will be restored. It is necessary to be clear that this state of the computer is required to power, suitable for a short period of time to leave the computer users. Although this state of the computer power consumption is very small, only a very low power consumption of physical memory.

Hibernate: Hibernation is not a new feature in Windows 7, extending from Windows XP to the present. By converting the computer to hibernation, you can quickly turn off the computer and stop all power to the computer. Windows, programs, and so on that are opened by the current user are copied from physical memory to the hard drive and saved as a hibernation file. After you save the hibernation file, shut down the computer completely. When you need to start your computer, press the power button on the host box and the computer will open as it would normally start. The difference is that when you start Windows, the hibernate file is copied from the hard disk into memory, and is displayed as "resuming windows." The benefit of this energy-saving state is to keep the programs and windows that are open to the user's computer and shut down the computer completely. But the overall start-up speed is still faster than normal cold start, suitable for a long time without the use of the computer users.
