How to speed up xp startup speed

I often hear computer users have such complaints: How do I open the computer after the self-test, the screen is always black, it takes half a day to have the XP interface appear? Why is my computer so slow to enter the system? The scroll bar has been rotated for more than a dozen laps and can't enter the system. Why doesn't my program click on any of the programs within a few minutes after my XP appears on the desktop? These problems can all be attributed to the slow startup of Windows XP. How can I speed up the system startup?

To solve the problem of slow XP startup, you must first understand the startup process of the system. The startup process of Windows XP can be roughly divided into five steps: First, pre-boot: First, the computer is powered on for self-test, and BiOS (the basic input and output system) scans the hardware and completes the basic hardware configuration, and then reads the hard disk. The MBR (Master Boot Record) checks the hard disk partition table to determine the boot partition and transfers the operating system boot sector on the boot partition to memory for 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 is to load the kernel: the boot process starts loading 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, XP 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. This article was published at http://bianceng.cn (learning computer)

Understanding the startup process of XP, we can take measures to speed up the startup.

1, prohibit unused peripherals

Because of the previous understanding of the boot process, we know that XP will automatically scan the hardware when booting, so if you disable some peripherals in WinXP It can effectively reduce the number of peripheral drivers that need to be loaded during system startup, thus speeding up the system startup. If you do not have a USB device on your computer, disable all USB devices in Device Manager - Universal Serial Bus Controller. This method can reduce your XP boot time by about fifteen seconds. Second, if you don't have multiple hard drives installed, you can also disable certain IDE devices to speed up startup. To do this, right click on "My Computer - Properties", then click on "Hardware" and then click on "Device Manager", open "IDE ATA/PATA Controller" (different chips are slightly different), then enter the main and respectively For the secondary IDE channel, select “Advanced Settings” and find the “Current Transfer Mode” as “Not Applicable” (this is the corresponding IDE channel). Set the “Device Type” of this item to “ No, you can be sure. Also note that since the system automatically reads the CD-ROM drive by default, the CD-ROM drive will be detected at startup. If the CD-ROM is placed in the CD-ROM drive, it will be read automatically. If it is a multimedia CD, the reading will take longer. Also extend the startup time of the computer. Therefore, it is recommended that you use the CD in peacetime and remember to take it out in time.

2, reduce the program loaded at startup

Probably many people have this feeling: XP startup speed is relatively fast at the beginning of system installation, but as the installed software continues to increase, The system will start slower and slower. This is because many software adds itself to the startup program, so that it needs to run when booting, which greatly reduces the startup speed and also takes up a lot of system resources. For such programs, we can exclude them from the startup group through the system configuration utility Msconfig. Select the "Run" command in the "Start" menu, type "Msconfig" in the "Run" dialog box, and the "System Configuration Utility" dialog box will pop up after you press Enter. Select the "Startup" tab, which is the tab. Lists the items and sources loaded at system startup. Check carefully whether each item needs to be loaded automatically. Otherwise, clear the check box before the item. The less items are loaded, the faster the startup will be. It is recommended that all operations except the reserved input method (ctfmon in the startup project) and the anti-virus monitoring program (such as RavTask) are prohibited from running automatically at startup.
