How to speed up XP startup speed

Often hear computer users have such a complaint: How I open the computer since the test screen has been black, to have a Half-day XP interface appears? Why does my computer get into the system so slowly? The scroll bars are turned more than 10 laps and cannot enter the system. Why does my XP click on any program in a few minutes after the desktop has no response? These problems can all boil down to the slow start of Windows XP. What can be done to speed up the system's start-up speed?

To solve the problem of slow XP startup, you must first understand the system startup process. The startup process for Windows XP can be roughly divided into 5 steps: First, pre-boot: First the computer power up for self-test, and the BIOS (that is, the basic input and output system) scans the hardware and completes the basic hardware configuration, and then reads the MBR (Master boot record) of the hard disk to check the hard disk partition table to determine the boot partition, and the operating system boot sector on the boot partition is transferred into in-memory execution, where the NTLDR (operating system loader) file is executed. The second step is to start: First, NTLDR will convert the processor to 32-bit protection mode from the original mode. Then read the Boot.ini file. The third step,. Mount 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. The hardware abstraction layer (HAL) is then loaded by the bootstrap process to complete this step. Step fourth, initialize the kernel: The kernel completes initialization, and NTLDR transfers control to the WINDOWS2000/XP kernel, which starts loading and initializing device drivers, and starts the WIN32 subsystem and Windows XP services. The fifth step is user login, after which XP will continue to configure the network device and user environment. Finally, with the system's boot music and our familiar desktop, the long Windows XP startup process is finally complete. This article is published in http://bianceng.cn (computer science)

With an understanding of the XP startup process, we can take measures to speed up the start-up.

1, prohibit the use of peripherals

Through the previous understanding of the startup process we know that XP will automatically scan the hardware at startup, so if you disable some peripherals in WinXP, you can effectively reduce the number of peripheral drivers that need to be transferred when the system starts up, thus speeding up the system's startup speed. If you do not have a USB device on your computer, disable all USB devices in the Device Manager-Universal Serial Bus controller. This method will allow you to reduce your XP boot time by about 15 seconds. Second, if you don't have more than one hard drive installed, you can also disable certain IDE devices to speed up your startup. The procedure is: right click on "My Computer-Properties", then click on "Hardware" and click "Device Manager", in which "IDE ata/pata Controller" (slightly different chips), and then enter the main and secondary IDE channels, select "Advanced Settings", where the "current transfer mode" is found "Not Applicable" (this is the corresponding to the unused IDE channel), set this item's "Device Type" to "none", OK. Also note: Because the system will automatically read the optical drive, so the start will be detected by optical drive, if the CD-ROM drive placed in the disc, will automatically read, if it is a multimedia CD so that the time spent on reading will be longer, the same extension of computer startup time. Therefore, we recommend that you use the CD in time to remember to take out.

2, reduce the loading process at startup

Probably a lot of people have this feeling: XP startup speed in the initial installation of the system is still relatively fast, but as the installation of the software continues to increase, the system will start faster and slower. This is because many software put themselves in the startup program, so the boot on the need to run, greatly reducing the start-up speed, but also occupy a large number of system resources. For such programs, we can exclude them from the startup group through the System Configuration Utility msconfig. Select the Run command from the Start menu, in the Run dialog box, type Msconfig, and the System Configuration Utility dialog box pops up, selecting the Startup tab, which lists the items and sources loaded at system startup, and carefully review whether each item needs to be automatically loaded , otherwise the current check box for the item is cleared, and the fewer items are loaded, the faster it starts. It is recommended that, in addition to retaining the input method (Ctfmon in the Startup project) and the antivirus monitoring program (such as Ravtask), everything else is prohibited from running automatically at startup.
