What can be done in Win8 security mode

Enter security mode can operate as follows:
1, system restore.
If the operating system fails and cannot be started normally and can enter safe mode, then you can try to recover the system in safe mode. Enter the safe mode in the "Control Panel" select "Restore", find the "Restore" option after the start button, you can restore the system without losing personal data.
2, add and remove programs, delete files that cannot be deleted.

When you delete some files in normal mode or clear the recycle bin, the system sometimes prompts "The file is being used and cannot be deleted", and you can delete it in safe mode. However, if you accidentally delete the files that the system really needs to use, the system will not start properly.
3, kill the virus in safe mode.
In the safe mode, it is allowed to load the necessary drivers. After entering the safe mode, you can open the anti-virus software and clean the virus.
4, install and uninstall the driver.
Partial failure to start due to driver failure of graphics card, sound card and other devices, disable in safe mode, uninstall these failed drivers, reinstall to solve the problem.
5, save the files in the system.
If the system is indeed unable to repair, you can enter the safe mode and use the mobile hard disk and other devices to export the data to prevent data loss.
