This article will explain in detail what the security mode in the computer means. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The safe mode of the computer is a special mode in the Windows operating system, which works by starting the computer without loading the third-party device driver to make the computer run in the minimum mode of the system, so that users can easily detect and repair errors in the computer system.

Safe mode is a special mode in Windows operating system. Friends who often use computers will not feel strange. In safe mode, users can easily fix some errors in the system and get twice the result with half the effort. The safe mode works by starting the computer without loading a third-party device driver and making the computer run in the minimum mode of the system, so that users can easily detect and repair errors in the computer system.

Operation steps

As long as you press the F8 key (or press and hold the Ctrl key when you start the computer) when you start the computer when you start the computer, press the F8 key before the system enters the Windows boot screen, and the operating system multi-mode startup menu will appear. Just select "Safe Mode" to boot the computer to safe mode.

In addition, when you are in Windows normal mode, click "start / run", type "msconfig", then select the "General" tab in the open window, then check "Diagnostic Startup-load only basic device drivers and services" and finally click "apply / OK" and restart, the system will automatically enter "safe Mode".

Solve the problem

Delete stubborn files

When we delete some files or clear the contents of the Recycle Bin under Windows, the system will sometimes prompt the words "so-and-so files are in use and cannot be deleted", but these files are not in use, so you can try to restart the computer and enter safe mode at startup. After entering safe mode, Windows automatically releases control of these files so that they can be deleted.

Safe Mode restore

If the computer does not start properly, you can use safe Mode or other startup options to start the computer, press F8 when the computer starts, select safe Mode in the Startup Mode menu, and then restore the system as follows:

Click "start" → "all programs" → "attachment" → "system tools" → "system restore", open the system restore wizard, and then select "restore my computer to an earlier time" option, click the "next" button, click the date shown in boldface on the calendar to select the system restore point, click the "next" button to restore the system.

Check and kill virus

There are more and more viruses every day, and antivirus software is updated every day. However, we are a little worried about antivirus under Windows, because they are very likely to be cross-infected. While some antivirus programs cannot run under DOS, we can of course boot the system to safe mode and make Windows load only the most basic drivers, so that the virus can be killed more thoroughly and cleanly.

Unlock Group Policy

In fact, group policy restrictions in Windows are implemented by loading registry-specific keys, which are not loaded in safe mode. Press and hold the F8 key after rebooting, and in the open multi-startup menu window, select safe Mode with Command prompt. After entering the desktop, type "C:WindowsSystem32XXX.exe (the program you started)" at the startup command prompt, start the console, then follow the above operation to lift the restrictions, and finally restart the normal login system to unlock.

Note: many restrictions on Group Policy cannot take effect in safe mode. If you encounter restrictions that cannot be lifted, you might as well go below to find a solution.

Repair system failure

If Windows is not stable or does not start properly, don't reinstall the system at this time, try to restart the computer and switch to safe mode to boot, and then restart the computer, has the system returned to normal? This method is very effective if there is a system failure caused by a problem with the registry, because Windows can automatically fix the registry problem when it starts in safe mode, and after successfully starting Windows in safe mode, it can generally start in normal mode (Normal).

Restore system settin

If the user cannot start the system normally after installing the new software or changing some settings, he or she also needs to enter the safe mode to solve the problem. If it is caused by the installation of the new software, please uninstall the software in safe mode. If you change some settings, such as the display resolution setting is beyond the display range of the display, resulting in a black screen, you can change it back after entering safe mode. Also put the screen saver with the password in the "start" menu, forget the password, resulting in the normal operation of the computer, you can also enter the safe mode to change.

Find a malicious self-starting program or service

If there are some inexplicable errors in the computer, such as not being able to get on the Internet and cannot find the problem according to the conventional way of thinking, you can start to have a look under the security mode with a network connection. If it can be done here, it means that some self-starting programs or services have affected the normal connection of the network.

Detect incompatible hardware

Due to the use of digital signature driver mode, XP detects all kinds of hardware more strictly than before, so some devices may not be able to drive in the normal state. For example, in some early CABLE MODEM, if you find that XP does not recognize hardware in normal mode, you can press F8 at startup, then select safe mode to detect new hardware in safe mode, and it is possible to correctly load the driver for CABLE MODEM.

Correct display resolution

If we set a resolution that is unacceptable to the display in the display properties, such as setting a resolution of 1600 × 1200 for a 17-inch CRT monitor, because we cannot check the display, we will not be able to change the resolution to a normal setting. It is true that Windows has a protection mechanism that when you set a resolution that is too high for the monitor to display, it will automatically return to the previous resolution after waiting for 30 seconds, but sometimes it may not work for a variety of reasons.

At this point, you can take advantage of safe mode, because in safe mode, the system will display a desktop with a resolution of 640 × 480. So we can safely boot the system to safe mode, set the correct resolution in the display properties, and restart the system to normal mode.

Remove stubborn software or virus Trojans

In normal mode, some viruses and Trojans (or even normal software) may not be removed correctly because they may be associated with some automatically loaded software. That's when you can try safe mode. Because in safe mode, most of these programs will not be loaded by the operating system, so we can rest assured to use antivirus / Trojan software to remove viruses and Trojans, or uninstall some software that cannot be uninstalled in normal mode as needed.

Although malware and viruses are becoming more and more cunning, and some may not be cleared in safe mode, removing software or virus Trojans in safe mode is a skill that beginners must master.

Disk defragmentation

If the system is used for a long time, there will be a lot of fragments in the hard disk, which will not only affect the performance of the system, but also waste valuable hard disk resources. Therefore, it is recommended that you regularly defragment the hard disk, and in the process of defragmentation, it is best not to run other programs, and generally in the normal startup of Windows, the system will load some automatic start procedures, and these procedures are not easy to close, often cause interference to the defragmentation program. In this case, we should restart the computer and enter safe mode, which will not start any automatic startup program to ensure the smooth progress of disk defragmentation.

Uninstall incorrect drivers

General drivers, if not suitable for your hardware, can be uninstalled through the XP driver. But the graphics card and hard disk IDE driver, if installed incorrectly, may crash as soon as you enter the GUI interface; the same is true of some motherboard ULTRA DMA patches, because Windows is to read memory and disk page files to adjust the computer state at any time, so the system crashes as soon as there is a problem with the hard drive. What are we going to do now?

In some cases, disabling the administrator account may cause maintenance difficulties. For example, in a domain environment, when the secure channel used to establish a connection fails for some reason, if there is no other local administrator account, you must restart the computer in secure mode to fix the problem that caused the connection state to be interrupted.

If you try to re-enable a disabled administrator account, but the current administrator password does not meet the password requirements, you cannot re-enable the account. In this case, the optional members of the administrators group must set the password for the administrator account through the Local users and groups user interface.

Resolve crashes caused by drivers or softwar

This problem may be encountered by many people, in this case, the only solution is to uninstall the new driver and restore the old version of the driver, but the problem is that Windows can not be started, how to uninstall and restore? If the driver you installed is for some non-important devices (such as network cards, graphics cards, sound cards, etc.), you can try to go into safe mode for recovery.

In safe mode, the system will only load the most basic driver, so as long as the system can enter safe mode, we can directly uninstall the driver, or Windows XP/2003 users can use the "return driver" function to return to the correct driver last time.
