I recently installed the Windows XP operating system. I know that when I press F8 at startup or when the computer does not boot properly, I will enter the advanced options menu of Windows XP startup. Here I can choose to start Windows XP in 8 different modes except normal startup. . What do these modes mean? Method (1) Safe Mode: When you start Windows XP in Safe Mode, the system uses only some of the most basic files and drivers to start. Entering safe mode is an important step in diagnosing a fault. If the problem cannot be determined after the security mode is started, or if the security mode cannot be started at all, then you may need to use the emergency repair disk ERD function to repair the system. (2) Network security mode: similar to security mode, but added support for network connection. This option is useful for troubleshooting Windows XP boot failures in a LAN environment. (3) Security mode of the command prompt: Similar to the security mode, only use basic files and drivers to start Windows XP. However, after logging in, a command prompt appears instead of the Windows desktop. (4) Enable boot log: Start Windows XP and log all drivers and services loaded by the system to a file. The file name is ntbtlog.txt and is located in the Windir directory. This log is useful for determining the exact cause of a system startup problem. (5) Enable VGA mode: Start Windows XP with the basic VGA driver. This mode is useful when a new graphics driver that prevents Windows XP from starting properly is installed, or because the refresh frequency is set incorrectly. When starting Windows XP in Safe Mode, only the most basic graphics driver is used. (6) Last time the correct configuration: Selecting "Start Windows XP with 'Last Known Good Configuration'" is a way to solve problems such as newly added drivers that don't match the hardware. Starting in this way, Windows XP only restores the information under the registry key HklmSystemCurrentControlSet. Any changes made in other registry keys remain the same. (7) Directory service recovery mode: Not applicable to Windows XP Professional. This is for the Windows XP Server operating system and is only used to restore the Sysvol directory and the Active Directory directory service on the domain controller. (8) Debug mode: Start WindowsXP and send debugging information to other computers via serial cable. If you are installing Windows XP on your computer with or without a remote installation service, you can see additional options related to using the Remote Installation Services recovery system. Attached: How to deal with Windows XP can not automatically shut down? After installing Windows XP, some computers do not automatically shut down after clicking to turn off the computer, but need to be manually turned off like the previous AT power. This is mainly because Windows XP does not enable advanced power management. Correction method: Click "Start → Control Panel → Performance and Maintenance → Power Options", in the power option property setting window that pops up, click "Advanced Power Management" and check "Enable Advanced Power Management Support".
