How to greatly improve the startup speed of WinXP system

I used to hear computer users complained: If I turn on the computer after the self-test, the screen is always black, it takes half a day to have the XP interface display? Why is my computer so slow to enter the system? The scroll bar has turned a dozen laps and can't enter the system. Why is it that my XP does not respond to clicking any program within a few minutes after displaying the desktop? These problems can all be attributed to the slow startup of Windows XP systems. What can I do to speed up the system startup?

If you want to solve the problem of slow XP startup, you must first understand the startup process of the system. The boot process of Windows XP can be roughly divided into five steps:

First step, pre-boot: First, the computer is powered on for self-test, and the BIOS (ie, basic input/output system) scans the hardware and completes the basic hardware configuration. , then read the MBR (master boot record) of the hard disk to check the hard disk partition table to determine the boot partition, and transfer the operating system boot sector on the boot partition into memory execution, where the NTLDR (Operating System Loader) file is executed. .

The second step, start: First, the initialization, NTLDR will convert the processor from real mode to 32-bit protection mode. Then read the BOOT.INI file.

The third step, loading the kernel: the boot process begins to load the XP kernel NTOSKRNL.EXE. This file is located in the SYSTEM32 folder under the Windows2000/XP installation folder. Subsequently, the hardware abstraction layer (HAL) is loaded by the boot process to complete this step.

The fourth step is to initialize the kernel: the kernel completes initialization, NTLDR transfers control to the Windows2000/XP kernel, which starts loading and initializing device drivers, and starts the WIN32 subsystem and the WINDOWSXP service.

The fifth step is for the user to log in. After logging in, the XP system application will continue to configure the network device and user environment. Finally, with the system's boot music and the familiar desktop, Windows XP's long startup process was finally completed.
