We often talk about processing in safe mode, but what exactly is safe mode? Today, I will popularize this knowledge for everyone! I hope I can help you! What exactly is the security mode and what does it do? 1. What is the security mode?

Sometimes, our system used to work normally, but after upgrading a buggy graphics card driver or installing a new version of antivirus software, the system can't start normally. In order to solve this kind of failure that will affect the normal operation of windows, but it is not Windows' own problem, then we can use safe mode.

when you log in to the system through "safe mode", you will see a very different desktop, just like the mode when you just installed Windows xp without installing any drivers. That's right. When Windows runs in safe mode, the system will only load the most basic services and drivers that can start the system, so that the operating system will run with the least drivers and services, and use the general graphics driver, working at the resolution of 64*48, and only support the keyboard, mouse, monitor and local hard disk, and open the default system services. In safe mode, Windows does not load drivers for audio devices and other unnecessary peripherals, and Windows also ignores all programs that run automatically when the system is started.

Second, how to enter the safe mode

Start the computer, and press F8 immediately after the hardware self-check. There are many advanced startup options listed here. Generally, we just choose to enter the normal security mode. In addition, you can also enter "safe mode" to start the system by holding down the Ctrl key when the computer starts.

If your computer is running, you can also click Start/Run-enter msconfig, and then select General in the window that opens, then check the item "Judge Start-Only Load Basic Device Drivers and Services", and finally click Apply/OK and restart, and the system will automatically enter Safe Mode.

Third, the role of safe mode

Role 1: Delete stubborn files

When deleting some files in Windows normal mode or deleting the recycle bin, the system can remind you that "the file is in use and cannot be deleted", so we can delete it in safe mode. Because in safe mode, Windows will release the ownership of these files.

Role 2: System Restore in Safe Mode

If your computer can't start now and can only enter Safe Mode, then you can restore the system in Safe Mode. After entering the safe mode, click Start → All Orders → Accessories → System Tools → System Restore, close the system restore wizard, then select the option of "Restore my computer to an earlier time", click the Next button, click the date displayed in bold on the calendar to select the system restore point, and click the Next button to restore the system.

Role 3: Virus killing in safe mode

Nowadays, the update speed of antivirus software can't keep up with the pace of viruses, so your computer will be infected by viruses if you are not careful. However, there are many viruses that can't be eliminated under Windows, and antivirus software can't run under dos.

At this time, we can start the safe mode, and the Windows system will only load the necessary driver sequence, so that the virus can be completely eliminated.

Role 4: Unlock the group policy in safe mode

In fact, the group policy restriction in Windows is completed by loading the specific key value of the registry, but this restriction will not be loaded in safe mode. Press F8 key after restarting the machine, and select "Safe Mode with Command Reminder" in the closed multiple startup menu window. After entering the desktop, output "C: C：WindowsSystem32XXX.exe" under the command reminder of startup, start the console, then follow the above operation to lift the restriction, and finally restart the normal login system to unlock it.

Note: Many restrictions of Group Policy cannot be invalidated in safe mode. If you encounter restrictions that cannot be lifted, you may as well go to the next place to find a way to deal with them.

Role 5: Repair system failure

If Windows is not stable and may not start normally, don't reinstall the system at this time, try to restart the computer and switch to safe mode to start, and then restart the computer. Has the system returned to normal? If there is a system failure caused by a registry problem, this method is very effective, because Windows can actively repair the registry problem when it is started in safe mode, and after it is successfully started in safe mode, it can generally be started in Normal mode.

Role 6: Restore the system settings

If the user has installed new software or changed some settings, causing the system to fail to start normally, it is necessary to enter the safe mode for processing. If it is caused by installing new software, please uninstall the software in the safe mode. If some settings have been changed, such as the display rate setting exceeds the display range of the monitor, causing a black screen, Then you can switch back after entering the safe mode, and you can put the screen screen sequence with clear codes in the "startup" menu. After forgetting the clear codes, you can't operate the computer normally and you can also enter the safe mode to change.

Role 7: Find out the malicious self-starting program

If there are some inexplicable errors in the computer, such as the inability to access the Internet, and the problem is found according to the conventional thinking, you can start it in the safe mode with network connection. If it works here, it means that some self-starting sequence or services have affected the normal connection of the network.

Role 8: Incompatible Hardware

XP adopts the digital signature driving sequence mode, and the detection of various hardware is stricter than before, so some equipment can not be driven under normal conditions. If you find that XP can't recognize hardware in normal mode, you can press F8 at startup time, and then choose to enter safe mode to detect new hardware in safe mode.

Role 9: Correct the display resolution

Under normal circumstances, Windows has a protection mechanism. When you set a resolution that is too high for the display to display, you will automatically return to the previous resolution after waiting for 3 seconds, but sometimes this function may not take effect for various reasons. At this time, we can use safe mode. In safe mode, the system will display the desktop with 64×48 resolution. At this time, we will set the correct resolution in the display properties and restart the system to normal mode.

The security mode of the computer is to log in to this mode for troubleshooting and repair when the operating system is abnormal. In this mode, the system will only start the underlying system, and other applications will not start, so users can easily troubleshoot some problems that cannot be solved in the system. The task principle of safe mode is to start the computer without loading the third-party equipment drive sequence, so that the computer can run in the system minimum mode, so that players can easily detect and repair computer system errors. What exactly is the security mode? 2

1. Delete stubborn files

For example, when we delete some files, we always prompt that they can't be deleted because of normal operation. At this time, you can enter the safe mode to delete, because the safe mode will hardly load any services and startup items.

2. Restore the system

When our system can't get into the normal mode, we can try to get into the safe mode. Then copy the lost files into the system. You can also restore the system through your original backup.

3. Antivirus

Many times, when you kill virus in normal mode, you will find that it can't be cleaned. At this time, because the virus is running, you will automatically produce a copy in another place after killing this place. . But if you kill virus in safe mode, you will find that the effect is very good! Because in safe mode, the virus can't run either. I can only wait for you to kill.

4. Unlock the group policy

In normal mode, the group policy can be run, that is, you disable it in the group policy. Some functions can be realized. But sometimes you want to use these functions, but if you turn off the group policy. At this time, you can go to the safe mode, restore the group policy, and just run normally after the difficulty.

the above is about the main use of security mode in the system. These four functions are very useful in our life. What exactly is the security mode and what does it do? 3

1. Special functions of the security mode:

1. Deleting stubborn files

2. Killing viruses

3. Unlocking group policies

2. Helping us to delete stubborn files

Stubborn files are usually prompted when we want to delete them, so-and-so processes are using or directly prompting system files. But sometimes you're sure it's not a system problem, or you don't even know that process is using it. At this time, we can easily delete these residual and stubborn files by entering the safe mode.

3. Kill the virus

You often find that the antivirus is not clean in the normal login interface. Why did I kill it clearly and come out later? This is because the virus has been combined with one of your programs under normal circumstances, deleted and born again. We just need to go to the safe mode and kill it easily, because the safe mode will not start other programs except the necessary system programs.

4. Unlock the group policy

In fact, the group policy restriction in Windows is realized by loading the specific key value of the registry, but this restriction will not be loaded in safe mode. Press F8 key after restarting the machine, and select "Safe Mode with Command Prompt" in the multiple startup menu window that opens. After entering the desktop, enter "C: C：WindowsSystem32XXX.exe" at the startup command prompt, start the console, and then follow the above operation to lift the restriction. Finally, restart the normal login system to unlock it.

The above is about the usefulness of the security mode of the system. Through the above solution, you will find out why many people solve computer problems. Everyone likes to go into safe mode to solve it. And if you can't get into the system, you can often solve it by entering the last security configuration. What exactly is the security mode and what is its function? 4

First, understand what is the security mode of mobile phone, which is a special mode of Android system and the same as the security mode of windows. You will find that the mobile phone runs its own software faster in safe mode, because the working principle of safe mode is to run without loading which software you downloaded.

It's not that there is something wrong with your mobile phone. It may be that you pressed the menu or volume button when you restarted your mobile phone, or that the software you downloaded needs ROOT permission, so you entered the safe mode.

method 1: directly and forcibly restart the mobile phone.

method 2: unplug the battery and wait for a few minutes, so that the phone can be reset and then turned on normally.

Method 3: Enter the settings of the mobile phone and restore the mobile phone to the factory settings. At this time, you should test out the relevant contacts or useful data in the mobile phone, but the software you downloaded may be gone and you must download it again.

method 4: because the software you downloaded needs root permission, something goes wrong, so delete it.

method 5: go to the mobile phone repair shop to brush the machine. What exactly is safe mode and what's its function? 5

People who often use computers may have heard that when the computer breaks down, Windows will provide a platform called "safe mode", where users can solve many problems, whether it's hardware (driver) or software. However, will you use this security mode? Today we will take you to know its true face.

getting acquainted with the safety mode

To enter the safety mode, just press F8 repeatedly when starting, and an options menu will appear, and then use the up and down cursor keys on the keyboard to select and enter different startup modes. The options menu includes the following:

1. Safe mode

Only basic files and drivers are used. Such as mouse (except USB serial mouse), monitor, keyboard, hard disk, basic video, default system service, etc., but there is no network connection.

if you can't successfully start the computer in safe mode, you may need to use the recovery console function to repair the system.

2. Security mode with network connection

Network connection is added on the basis of ordinary security mode. However, some network programs may not run normally, such as MSN, and many self-starting applications will not automatically load, such as firewalls and antivirus software. So don't forget to load it manually in this mode, or malicious programs may invade your computer while you are repairing it.

3. Safe mode with command prompt

Only basic files and drivers are used 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. You can press Ctrl+Alt+Del to bring up Task Manager, click New Task, and then enter "C:WINDOWSexplorer.exe" after "Run" in the pop-up dialog box to start the graphical interface of Windows XP immediately, which is exactly the same as the interfaces in the above three security modes. If you enter "c:windowssystem32cmd", you can open the command prompt window again. In fact, this method can also be used to start the command prompt window in other security modes or even during normal startup. What is the safe mode and what is its function? 6

First, delete stubborn files

When using a computer, under normal circumstances, some files may be deleted or the recycle bin may be eliminated, the system can remind that "the file is in use and cannot be deleted", and when it is forcibly deleted without using software, we can enter the safe mode to delete it. Windows will voluntarily release the ownership of these files.

second: restore the system in safe mode

in the daily use of the computer, you will not be able to boot into the system for free, so you have to restart to enter safe mode. In this case, we can restore the system. After entering the safe mode, click Start → All Orders → Accessories → System Tools → System Restore, close the System Restore Wizard, and then select Restore Me.
