When the Windows system fails to start or run normally due to certain errors, in order to improve the security of the system itself, you can enter safe mode at startup.
Safe mode is a special mode in the Windows operating system. Friends who often use computers will definitely not be unfamiliar with it. In this mode, users can easily fix some system errors, achieving twice the result with half the effort. (Recommended learning:web front-end video tutorial)
The working principle of safe mode is to start the computer without loading third-party device drivers, so that the computer runs at the minimum system level mode so that users can easily detect and repair computer system errors.
Main functions of safe mode
Delete stubborn files
We delete some files or clear them under Windows When retrieving the contents of the Recycle Bin, the system sometimes prompts the message "A certain file is in use and cannot be deleted." However, these files are not in use. In this case, you can try to restart the computer and enter safe mode at startup. After entering safe mode, Windows will automatically release control of these files and you can delete them.
Restore
If the computer cannot start normally, you can use "Safe Mode" or other startup options to start the computer. Press the F8 key when the computer starts. Select Safe Mode in the Mode menu, and then perform system restore as follows:
Click "Start" → "All Programs" → "Accessories" → "System Tools" → "System Restore" to open the System Restore Wizard. Then select the "Restore my computer to an earlier time" option, click the "Next" button, click on the date shown in bold on the calendar to select the system restore point, and click the "Next" button to perform system restore.
Virus checking
There are more and more viruses every day, and anti-virus software is also updated every day. However, we are a little worried about antivirus under Windows because they are very likely to be cross-infected. And some anti-virus programs cannot run under DOS. At this time, of course we can also boot the system into safe mode so that Windows only loads the most basic drivers, so that the virus can be killed more thoroughly and cleaner.
