Five important uses of Windows security mode (1)

                    For the security mode of the Windows operating system, friends who often use the computer will certainly not be unfamiliar. The security mode is a dedicated mode used by Windows to repair operating system errors. It is a minimal system environment that does not load any drivers. Start the computer in safe mode. It is convenient for users to eliminate problems and fix errors. This is also convenient for everyone to explain the security mode to users.

To enter the safe mode, start the computer and press the F8 key (or hold down the Ctrl key while booting the computer) before the system enters the Windows splash screen. In the boot options menu that appears, select " Safe Mode", which means you can start your computer in safe mode. So what is the use of security mode? Let us take a closer look.

1. Fix system failure

If Windows is not stable or does not start properly, don't worry about installing the system first, try restarting the computer and switching to safe mode. After restarting the computer, has the system been restored? If the system is faulty due to a problem with the registry, this method is very effective, because Windows can automatically repair the registry problem when it starts in safe mode. After booting Windows in safe mode, it can generally be in normal mode (Normal) ) started up.

2, restore system settings

If the user is installing new software or changing some settings, the system will not start properly, you need to enter safe mode, if it is If the new software is installed, please uninstall the software in safe mode. If some settings are changed, 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. Put a screen saver with a password in the "Startup" menu. If you forget your password, it will not work properly and you can enter safe mode changes.

3, delete stubborn files

When we delete some files under Windows or clear the contents of the recycle bin, the system sometimes prompts "quote a certain file is being used, can not delete" The words are interesting. Usually, these files are not being used. So, are these files always occupying our hard disk? Please don't worry, restart your computer, and press F8 to enter safe mode at startup, try to delete those stubborn files and empty the recycle bin to see it, no more! It turns out that Windows has given up on the protection of these files and can delete them.

4, the elimination of the virus

Now every day more than the virus, antivirus software updates every day to follow. However, in Windows normal mode, sometimes it is not possible to clean the virus cleanly and thoroughly, because they are very likely to cross-infect, and some anti-virus programs can not run under DOS. At this time, of course, we can also boot the system to safe mode. Make Windows only load the most basic drivers, so it is more thorough and cleaner to kill the virus.

5, disk defragmentation

During the defragmentation process, other programs cannot be run, because the defragmentation program will automatically restart whenever other programs perform disk read and write operations. Start, and generally when you start Windows normally, the system will load some automatically started programs, sometimes these programs are not easy to manually close, often cause interference to the defragmentation program, in this case, we should restart the computer, enter security Mode, safe mode does not start any automatic startup program, can ensure the smooth defragmentation of the disk.
