What is the role of Windows 7 system security mode? The security mode of Windows is to troubleshoot and repair after logging into this mode when the operating system is abnormal, in which case the system will only start the underlying service, the other applications will not start, and the user can easily troubleshoot the system. Safe Mode works by starting a computer without loading a third-party device driver, so that the computer runs in the minimal mode of the system so that users can easily detect and repair computer system errors. Let's learn more about the Windows 7 security model below.
How to access Windows 7 security mode

Method Two: Hold down the CTRL key while starting the computer. There will be a system of multiple Operation boot menu, this time you only need to select "SafeMode", you can directly into the safe mode.
Operating Guide in Windows 7 Safe mode
1. Delete Stubborn documents
When you delete some files in normal Windows mode or when you purge the Recycle Bin, the system may be prompted to "file is in use and cannot be removed", and we can delete it in safe mode. Because in safe mode, Windows automatically frees up control over these files.
2. System Restore in Safe mode
If your computer doesn't start now and can only go into safe mode, then you can restore the system in Safe mode. After entering safe mode, click "Start" → "All Programs" → "Accessories" → "System Tools" → "System Restore", open the System Restore Wizard, and then select the "Restore my Computer to an earlier time" option, click the "Next" button, click the date on the calendar to select the System Restore point, click " The Next button is available for System Restore.
3. Virus killing in Safe mode
Now anti-virus software update speed has not been able to keep up with the pace of the virus, slightly inattentive to your computer will be infected with the virus. But in Windows Anti-Virus has a lot of viruses can not be removed, and in DOS anti-virus software can not run. This time we can start Safe mode, the Windows system will only load the necessary drivers, so that the virus can be completely removed.
4. Unlock Group Policy in Safe mode
In fact, Group Policy restrictions in Windows are implemented by loading registry-specific key values, and this restriction is not loaded in safe mode. After rebooting, hold down the F8 key and select "Safe Mode with Command Prompt" in the Open Multiple Boot menu window. After entering the desktop, at the start of the command prompt input "C:windowssystem32xxx.exe (you start the program)", start the console, and then the operation can be lifted, and finally restart the normal login system can unlock. Note: Many of the Group Policy restrictions in Safe mode can not be effective, if you encounter the restrictions can not be lifted, you may wish to enter the next search for solutions.
5, repair system failure
If Windows is running unstable or does not start properly, then do not focus on the system, try to restart the computer and switch to Safe mode to boot, and then restart the computer, the system has returned to normal? This method works well if a system failure is caused by a problem with the registry Because Windows automatically fixes the registry problem when it starts in safe mode, and when you start Windows successfully in Safe mode, you can normally start under normal mode (normal).
6, restore the system settings if the user is installed new software or changed some settings, causing the system will not start normally, also need to go into safe mode to resolve, if the new software is installed, please uninstall the software in Safe mode, if it is changed some settings, For example, display resolution settings beyond the display range, resulting in a black screen, then enter the safe mode can be changed back, as well as the screen saver with the password on the "Start" menu, forget the password, resulting in the normal operation of the computer, can also enter safe mode changes.
7, to find out the malicious from the start of the program or services if the computer appears some errors, for example, not on the net, according to conventional thinking and no problem, you can start to the Safe mode with network connection to see, if here can, it shows that some from the start program or services affect the network's normal connection.
8, the detection of incompatible hardware XP because of the use of digital signature driver model, the detection of a variety of hardware is also more stringent than before, so some equipment may not be in the normal state of the drive to use. If you find that XP does not recognize the hardware in normal mode, you can press F8 at startup and then enter Safe mode to detect new hardware in Safe mode.
9, uninstall the incorrect driver
The general driver, if not applicable to your hardware, can be uninstalled via XP driver. But the graphics card and hard drive IDE driver, if installed incorrectly, it is possible to enter the GUI interface on the crash; The same is true for some motherboard ULTRADMA patches, because Windows is ready to read memory and disk paging files to adjust the state of the computer, so the hard drive will crash as soon as there is a problem. What do we do now?
In some cases, disabling the administrator account can cause maintenance difficulties. For example, in a domain environment, when the secure channel used to establish a connection fails for some reason, if there are no other local administrator accounts, you must restart the computer in Safe mode to fix the problem that caused the connection state to be interrupted.
If you attempt to re-enable an administrator account that is disabled, but the current administrator password does not meet the password requirements, you cannot re-enable the account. In this case, an optional member of the Administrators group must set the password for the administrator account through the Local Users and Groups user interface
