Open the computer every morning, do you think your machine is always slower than others? In fact, we can optimize the computer and speed up the computer without spending a penny. 1. Priority booting from the hard disk There are many people who ignore the boot order of the devices in the computer. Many people will boot from the CD-ROM by default, so that the CD-ROM drive will be read at boot time. If there is a CD-ROM in the CD-ROM drive, it will delay you. Boot up. Even if there is no CD, it will let the CD-ROM drive read when the system starts, which is not good for the life of the CD-ROM. Therefore, we need to close it. Press the Del key to enter the BIOS setup program, select the BIOS Features Setup menu, and press the Enter key to enter the parameter setting options interface. In this interface, find and select the option Boot Sequence, then press the Page Down key or the Page Up key. Select CDROM, C, A to set the system to boot from the C drive first, and finally press the Esc key to return to the root menu and select the save menu or directly press the F10 key to save the settings. If you are using the Phoneix BIOS, press the F2 key at boot time, enter the BIOS settings, select the Boot option, then find the HardDrive item, and press the “+” key to make it to the front. Ensure that the machine is booted from the hard disk first. 2. Enable Quick Boot Most computers have a Quick Boot item in the BIOS. Under “Advanced BIOS Features”, set it to Enable so that the BIOS does not perform hardware every time it is booted. Detection can greatly speed up system startup. 3. Masking unnecessary devices Although the current parallel port and serial port are no longer popular, there are still many interfaces on the motherboard. At this time, we can completely shield it in the BIOS, which can also speed up the system startup. Enter the BIOS, and then select the "PNP, PCI & ONBOARD I /O" option, select the Onboard Serial Port1 under it, press the PageUp or PageDown button, set it to the Disable state, you can turn off the serial port, press Press the F10 key, save the changes, and restart the system. Of course, this method can also lock IDE2, parallel port, USB and floppy drive, etc., so that Windows can not load their drivers, naturally it will be much faster. 4. Disable unnecessary hardware in Windows For hardware that is not used on the machine, do not let Windows reload their drivers, you can open the “Control Panel”, double-click the “System” icon, and then click ““ Hardware & rdquo; tab, click the "Device Manager" button to open "Device Manager", right click on the corresponding device, select "Attributes", and then click in the window that opens "Device Usage" ” drop-down list box, select “ Do not use this device (disable) & rdquo;, click the "OK" button to confirm the change twice. 5. Reinstall the hardware If you have more than one hardware installed on your computer, make sure they are no longer useful. It is not wise to uninstall them one by one, because most people don't know where these drivers are scattered on the hard disk, and it is impossible to clean them. At this time, we can remove all unused hardware, then insert the Windows installation CD into the CD-ROM drive, open the SUPPORT\\TOOLS folder, double-click the DEPLOY.CAB file, and extract all the files to a folder (such as d:\\Sysprep), double-click the sysprep.exe file and press the “OK” button to accept the warning message. And select the "Do not reset active grace period", "Use minimal installation" and "Detect non-Plug and Play hardware" checkboxes in the window. Press the "Reclose" button and the machine will automatically turn off. After restarting the computer, Windows XP will let us accept the protocol, enter the serial number, and specify the system administrator and password, and will re-detect the hardware and reinstall the driver. Because Windows re-detects and installs the driver, the hardware in such a system is “clean”, there will be no redundant drivers, and the system will naturally be much faster. 6. Prohibit unnecessary services Now most people use Windows 2000/XP system, but there are more than 90 services, up to 30 by default! In fact, as long as 6 is enough, it is forbidden to "all do not need" services will save 12-70MB of memory, making our computer faster. Press Win+R, then services.msc and press Enter to bring up the system service management window. At this time, you can see the services in the system. Each name is followed by a description. Double click on any service will pop up a Property window. If you feel that this service does not have much effect, you can click the “Stop” button and click the “Start” button to open the service. After adjusting the open state of the service, restart the system to take effect. Of course, it's not easy to remember that the use of these services is not easy. Sometimes it is forbidden to quit a service that cannot be banned. A better approach is to download a script from http://www.ntsvcfg.de/svc2kxp.cmd, double-click the file after downloading, it will open a Windows command line window listing 4 service configurations. Options: LAN, Standard, ALL, Restore. You can press the number keys to select, the LAN is for machines that need to use a LAN, the Standard is for a standalone machine with an Internet connection but no LAN, and ALL uses the most aggressive optimizations discussed on the site. The Standard is more in line with the optimization scheme recommended in this article. This script will change the running status of Security Accounts Manager, TCP/IP NetBIOS Helper and Windows Management Instrumentation to “manual”. If you are not satisfied with the modified effect, you can choose Restore to restore the previous settings. In addition to not being able to shut down Netbios, this script is very automated. Since the script uses sc.exe to start and terminate the service, if you don't have sc.exe on your machine (if you use Windows 2000), you will be prompted to download it automatically, just press the Y button in the DOS window. . & rsquo; 7. Prohibit auto-run programs. Every time you start your computer, it always feels very slow. After the startup is completed, it is found that the tray area in the lower right corner always shows some icons one by one, that is, you automatically start the program too much. Clear them, you can also speed up the startup, and more importantly, you can remove some hidden Trojans! First download the software from http://www.mlin.net/files/StartupCPL.zip, then open it with WinRAR, then double-click StartupCPL.exe to complete the installation. Then open the “Control Panel” and double-click the Startup item. In the dialog box that opens, you can easily manage the startup items in the “Startup” folder and the registry. For example, right click on the blank space to create a new one. Start the project, right-click on the existing startup project to edit, delete, disable, and run it immediately. The program "according to the ground" when the weight loss is now, the hard disk capacity is hundreds of GB, it should be relatively large. But Microsoft-led software vendors are not convinced that we have 1.5GB for Windows XP, nearly 2GB for Windows 2003, and more than 800 MB for Office 2003 (think Windows tens of megabytes) …… So, if you don't pay attention, your space is not enough. However, there is also a lot of garbage in our system. After clearing these big households, it will make the system much more refreshing. This article comes from [System Home] www.xp85.com
