The use of windows system security mode

  

The way to enter the safe mode is: start the computer, before the system enters the Windows splash screen, press the F8 key (or hold down the Ctrl key while starting the computer), the startup that occurs From the options menu, select “Safe Mode”. Start your computer in safe mode. So what is the use of security mode? Let us take a closer look. 1. Repair the system failure If Windows is not stable or does not start properly, don't worry about installing the system first, try to restart the computer and switch to safe mode to start, then restart the computer, the system has been restored. Normal? 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. Restoring system settings If the user is installing new software or changing some settings, the system will not start properly, and it needs to be solved in safe mode. If it is caused by installing new software, please be in safe mode. Uninstall the software. 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 the safe mode, and put a screen saver with a password on the list. In the Startup menu, if you forget the password, the computer will not operate properly, or you can enter the safe mode change. 3. Delete stubborn files When we delete some files or clear the contents of the recycle bin under Windows, the system sometimes prompts “some files are being used, and the words “cannot be deleted” are interesting. Generally, these files are not Being used, isn't it making these files always occupy our hard drive? 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. Thoroughly remove the virus Now that the virus is more than one day, the anti-virus software is 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 the other programs perform disk read and write operations. Generally, when Windows is started normally, the system will Load some programs that are automatically started. Sometimes these programs are not easy to close manually, which often interferes with the defragmentation program. In this case, we should restart the computer and enter the safe mode. The safe mode will not start any automatic startup program, which can ensure the smooth defragmentation of the disk!
