How does the system security mode enter and function

24 hours a day, except for sleeping time, most of the time is spent on the computer, even so, we are still a computer rookie, unfamiliar with the computer system, the operation of the computer The process is also half-baked. When the computer is poisoned, I only know that I use anti-virus software to kill the virus, but in the face of some deep-rooted viruses, even the anti-virus software seems to be helpless. At this time, when you ask for help, there will be a computer expert telling you: enter safe mode and manually delete the virus program. What is the security mode of the operating system? Let's take a look at it today.
Security mode is a system mode provided by the operating system. As the name suggests, it is the operating mode under the premise of security. Generally, when we just start the machine, click F8 to enter the safe mode.
The working mode of the safe mode is to disable all non-system startup items, so that users can detect and repair system errors. So the security mode is generally a system mode that is used when there is a problem with normal startup. So, when you encounter any problems, you can solve it by entering the safe mode?
First, if the system fails due to improper installation of some software, if the uninstall operation cannot be performed in the normal startup mode, then you can enter the security. Mode, uninstall this software.
Secondly, if the system fails to start because some values ​​of the registry are modified, you can also enter the safe mode, because the registry problem can be automatically fixed after the security mode is successfully started.
At the end of the day, there is a situation that everyone usually pays little attention to, that is, when defragmenting the disk, it is best to do it in safe mode, because in the process of defragmentation, it is best not to run any other program. If defragmentation is performed under normal startup, the system will load some automatically started programs, which is not conducive to the finishing process.
Is the above steps simple and clear? In short, if you encounter problems and system failures that are encountered during normal startup of the computer in the future, they can be solved and handled in safe mode.
