What can Windows Safe Mode do?

To enter the safe mode, 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). 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, the repair system failures

If Windows is running up and not very stable or not start, this time do not just reinstall the system, try restarting your computer and switch to Safe mode starts, then restart 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.
