Everyone knows that Windows security mode can be described as a lifeline for system failure. Once the system is abnormal, many users immediately think of using safe mode, because when the computer fails, whether it is hardware (driver) or software, Windows will Provide a platform called "Safe Mode", which can help users solve problems. Do you know about it? Would you use this security mode? Let me know about it today.
First, Windows security mode initial solution
To enter the safe mode, as long as you press F8 at startup, the option menu will appear, and then use the up and down cursor keys on the keyboard to select to enter a different boot mode.
The options menu includes the following:
1. Safe mode uses only basic files and drivers. Such as mouse (except USB serial mouse), monitor, keyboard, hard disk, basic video, default system service, etc., but no network connection.
If you are unable to boot your computer successfully in Safe Mode, you may need to use the Recovery Console feature to repair your system.
2. The security mode with network connection adds network connection based on the normal security mode. However, some network programs may not work properly, such as MSN, and many self-starting applications do not automatically load, such as firewalls, anti-virus software, and so on. So in this mode, don't forget to load manually, otherwise malicious programs may invade during the process of repairing your computer.
3. Safe mode with command line prompt uses only basic files and drivers to start. After logging in, the command prompt is displayed on the screen instead of the Windows graphical interface.
Note: In this mode, if you accidentally close the command prompt window, the screen will be completely black. Press the key combination Ctrl+Alt+Del to bring up the “Task Manager”, click “New Task”, and then enter “"C:\\WINDOWS\\ in the pop-up dialog box after “Run”. Explore..exe”, can immediately start the graphical interface of WindowsXP, exactly the same interface as the above three security modes. If you enter “c:\\windows\\system32\\cmd” you can open the Command Prompt window again. In fact, the command prompt window can be launched in this way when other security modes start normally.
4. Enable startup to start in normal security mode and log all drivers and services loaded (or not loaded) by the system into a text file. This file is called ntbtlog.txt and is located in the %windir% (default is c:\\windows\\) directory. It is useful to start the ambiguity to determine the exact cause of the system startup problem.
5. Enable VGA mode to boot with the basic VGA driver.
This mode is useful when a new video card driver that prevents Windows from starting properly is installed. In fact, no matter which form of security mode is used, it always uses the basic video driver. Therefore, in these modes, the resolution of the screen is 640 & times; 480 and cannot be changed. However, the driver can be reinstalled.
6. The last correct configuration was started using the registry information and drivers saved when Windows was last closed. Any changes made since the last successful start will be lost. Therefore, the last correct configuration is generally used only when the configuration is incorrect (mainly software configuration). However, it does not solve the problem caused by the driver or file being damaged or lost.
7. Directory Service Recovery Mode This is for the server operating system and is only used to recover the SYSVOL directory and Active Directory directory service on the domain controller.
8. Debug mode is sent to another computer via a serial cable when booting.
If you are installing or installing Windows on your computer using the Remote Installation Service, you can see additional options related to restoring or restoring your system using Remote Installation Services. A recovery screen is normal display
In the past, it was an old monitor, and it was a beginner. The beginners loved to do the wallpaper. The resolution also felt very fulfilling. I didn’t expect to mistake the resolution and refresh. The rate is too high, and the screen will be screened the next time it starts, so it is necessary to reinstall the operating system.
I think it’s so cute at the time, just restart it to safe mode (the first four modes above), delete the graphics driver and restart the computer. When restarting (normal startup), the system will automatically scan the graphics card and install the driver, and the screen will resume normal display.
There are still some problems that can be handled by this method. For example, Windows XP will automatically recognize the hardware and install the driver, but sometimes it is always dizzy, and the error message will not be displayed under the device manager, but it is not working properly, as above Can not network (network card driver is wrong), the screen display is wrong (the graphics card driver is wrong), etc., you can also reinstall the driver in safe mode.
Second, the malicious self-starting program or service
If the computer has some inexplicable errors, such as not being able to access the network, according to the conventional thinking, can not find the problem, can be started to see the security mode with network connection Look, if you can do it here, it means that some self-starting programs or services affect the normal connection of the network.
In the secure mode with network connection, use the command prompt tool TaskList>d:\\Anquan.txt with redirection to record the current process to the text file Anquan.txt in the D: root directory. Then, start the computer in the normal way, compare the process recorded in Anquan.txt with the process at this time, you will find that there are many more processes at this time, please end the extra process one by one and check the network connection. Is it normal? If the network connection is normal when ending up to a process, the process that just ended is the culprit. Once detected, the process-related executables can be deleted. However, it should also be noted that since it is automatically run, after forcibly deleting, it may cause the startup time to report the error of not finding a file & rdquo;, and also clear all settings related to self-start, including &ldquo "System Configuration Utility" "Startup">,""Win.ini” content under the registry, content under the startup script, “start”menu"start” Wait.
