Many people are new to the concept of security mode. In fact, the security mode is to start the computer without loading third-party device drivers, so that the computer runs in the system minimum mode, so that users can easily detect and repair computer system errors. . So, what can he do? How does it help our daily work?
What is the security model?
We all know that for the current Windows 2000/XP/2003 operating system, the stability of the system itself has been Not a problem, and a large number of drivers and applications are the main culprits that compromise system stability and reliability. Maybe the system is working very well, but after upgrading a graphics card driver with a bug or installing a new version of anti-virus software, the system will not start properly. In order to solve this kind of failure that will affect the normal operation of Windows, but not Windows itself, Microsoft has prepared a security mode for us.
Login to the system through the "safe mode" mode, the desktop you see is very different from what you usually see, just like the mode when you just installed the system without installing any drivers in Windows 98 system. The fact is that when Windows is running in safe mode, the system will only load the most basic services and drivers that can boot the system, so the operating system will run with minimal drivers and services, and use a generic graphics card. Driver, working at 640× 480 resolution, only supports keyboard, mouse, monitor, local hard drive, and open the default system service. In safe mode, Windows does not load drivers for audio devices and other non-essential peripherals, and Windows ignores all programs that run automatically with the system.
Tip: The universal graphics driver in Windows XP/2003 will display 24-bit color depth and 640 x 480 resolution in safe mode, however these settings cannot be modified.
How to enter safe mode
Pressing the F8 key during startup is the most traditional and most common method: When we turn on the computer and the hardware completes the self-test, immediately press the F8 key on the keyboard. A number of advanced startup options are listed here. In this safe mode is divided into several types, in general, we choose to enter the normal security mode. In addition to this most common method, hold down the Ctrl key while the computer is starting up, or you can start the system in “safe mode”.
In addition, when you are in the normal mode of Windows, click “Start/Run", enter “msconfig”, then select the “General” tab in the window that opens, and then check &ldquo The assertion start - load only basic device drivers and services & items, and finally click “ application /OK & restart, the system will automatically enter "safe mode".
Using Safe Mode to Solve Actual Problems
Now you probably know the meaning of safe mode, but how to use it? Let us tell you by example!
1, repair system failure
Sometimes, Windows is not stable or does not start properly. At this point, you can try to use "Safe Mode" to solve the problem. Try restarting the computer and switching to "Safe Mode" to start, successfully restart the system in "Safe Mode", and then restart the computer in normal mode, so that the system will automatically repair in "Safe Mode" Some registry files and some system files that may be wrong, some less serious system errors will be fixed.
2, solve the driver or software caused by the crash
This problem may be encountered by many people, in this case, the only solution is to uninstall the new driver, restore the old version of the driver, but the problem is that Windows can not Start up, how to uninstall and restore? If you install the driver for some non-critical devices (such as network card, video card, sound card, etc.), then you can try to enter safe mode for recovery.
As mentioned earlier, in safe mode, the system will only load the most basic drivers, so as long as the system can enter safe mode, we can directly uninstall the driver, or Windows XP/2003 users can use “ The driver & rdquo; function returns the last correct drive.
3, correct the display resolution
If we set the display in the display properties unacceptable resolution, such as the 17-inch CRT display set 1600 & times; 1200 resolution, because can not check the display, we It is also impossible to change the resolution to the normal setting. It's true that Windows has a protection mechanism. When you set a resolution that is too high and the monitor can't display it, you only need to wait for 30 seconds to automatically restore to the previous resolution. However, sometimes it may not be possible for various reasons. Effective.
This time you can use the safe mode, because in safe mode, the system will display 640 & times; 480 resolution desktop. Therefore, we can safely start the system into safe mode, set the correct resolution in the display properties, and restart the system to normal mode.
4, disk defragmentation
The system has been used for a long time, there will be a lot of debris in the hard disk, more debris will affect the performance of the system, will also waste valuable hard disk resources. Therefore, it is recommended that you defragment your hard disk regularly. In the process of defragmentation, it is best not to run other programs. Generally, when you start Windows normally, the system will load some programs that are automatically started, and these programs are not easy to close. Often, it interferes with the defragmentation process. In this case, we should restart the computer and enter safe mode. Safe mode will not start any automatic startup program, which can ensure the smooth defragmentation of the disk.
I believe that after learning this tutorial, everyone has a basic understanding of the security model and its typical application. However, there are still many functions of the security mode. I hope that beginners can think of “safe mode” when they encounter specific computer problems. Maybe many problems will be solved.
