Talking about the five important uses of Windows security mode

For the security mode of Windows operating system, friends who often use computers will certainly not be unfamiliar. Security mode is a special mode used by Windows to repair operating system errors. It is a kind of Do not load any driver's minimum system environment, start the computer in safe mode, it is convenient for users to eliminate problems and fix errors, which is convenient for everyone to explain the security mode to users.
To enter the safe mode: Start the computer, press the F8 key before the system enters the Windows splash screen (or hold down the Ctrl key while starting the computer), in the boot options menu that appears, select "Safe" Mode", that is, the computer can be started in safe mode. So what is the use of security mode? Let us take a closer look.

1, repair system failure

If Windows is not stable or can not start properly, do not focus on the system at this time, try to restart the computer and switch to safe mode to start 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 the password, the computer will not operate properly and you can enter the safe mode change.

3, delete stubborn files

When we delete some files under Windows or clear the contents of the recycle bin, the system sometimes prompts "some files are being used, can not be deleted" What's interesting is that usually these files are not being used, so is it necessary to let these files occupy our hard disk forever? 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, completely remove the virus

Now the virus is more than one day, anti-virus software is also updated every day. 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 interfere with 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.
