How to build a solid Win 2000 system

Windows 2000 has always given the impression of security and stability, which is why it has always been the operating system of choice for development platforms and networks. But perhaps because it is too powerful and too powerful, its speed and hardware requirements have always been unsatisfactory. The author has accumulated some experience in practice, through some steps to optimize and adjust the Windows 2000 system, can greatly improve the running speed of Windows 2000, and create a powerful and stable Windows 2000 system.

Optimizing the development platform with Windows 2000 Professional

1. Memory Optimization

After the system is installed, the application is not set to use the memory in the background service by default. This way the memory has been optimized. Now to optimize, just set the size of the virtual memory, by right-clicking "My Computer", select "Properties /Advanced /Performance Options /Change", set the initial value and maximum value of virtual memory, will initially The value is set to 2.5 times your machine's memory, the maximum value is set to the maximum size you need, be careful not to exceed the available space on the hard disk. The virtual memory is saved on the hard disk by a swap file named Pagefile.sys. The Winfile.swp of Pagefile.sys and Win 98 are of the same nature. The swap file should be stored on the fastest hard disk, usually stored in the C drive. Or the largest one. In addition, in the registry, setting ClearPageFileAt Shutdown=1 in HKEY_LOCAL_MACHINE/System/CurrentControlSet/Control/SessionManager/Memory Management can also improve performance. If your machine's memory is ≥128MB, you can also perform the following two optimizations:

1. Set DisablePagingExecutive=1 in HKEY_LOCAL_MACHINE/System/Current ControlSet/Control/Session Manager/Memory Management, indicating that the system is running. Files are forced to remain in memory without moving into virtual memory, which speeds up the program.

2. Set LargeSystemCache=1 in HKEY_LOCAL_MACHINE/System/Current ControlSet/Control/Session Manager/Memory Management, which means that Win 2000 uses its system cache, which will greatly improve the disk input/output performance. .

2. Hard Disk Optimization

The hard disk transfer mode must be set to DMA. If your hard drive supports DMA, replacing DMA with DMA can increase the speed of the hard drive and reduce CPU usage. To do this, right click on My Computer→Management→Device Manager→IDE ATA/ATAPI Controller→Primary IDE Channel→Properties→Advanced Settings to select DMA in transfer mode. In addition, the Windows 2000 partition can use NTFS format to better play the system performance. If your system partition is FAT or FAT32, you should convert it to NTFS. You can use Windows 2000 "convert drive" in DOS mode: /FS:NTFS [/V]" command to complete.

At the same time, you can use the following methods to increase the speed of the hard disk:

(1) Right-click on my computer to select properties, select the properties of the hard disk in the device manager, and enable "write caching". "Choose. Use DOS Smartdrv management instead of Win 2000 Smartdrv to enable at least 4MB of buffer for the boot disk. To do this, add C:WindowsSmartdrv.exe /E:4096 /B:4096 to C:Auotoexec.bat.

(2) often use the disk defragmentation program, not only can organize the files to be stored on the hard disk continuously, but also can move the commonly used files to the hard disk partition, reduce the seek time of the hard disk, and speed up the startup. speed.

3. File System Optimization

Optimizing the file system is also critical to improving system performance, and the file system can be optimized in the registry. In HKEY_LOCAL_MACHINESystemCurrent ControlSetControlFileSystem, the new value ConfigFileAllocSize, DWORD type, set the key value is 000001f4, which can optimize the file system and improve system performance.

4. Optimization of desktop and start menu

Regarding folders, the system uses Web view by default, that is, there is an information bar on the left to display the selected file information, and if it is a picture file, a thumbnail of the picture will be displayed. Using this method can bring a lot of memory, but it will waste a lot of memory. Turning it on will reduce system performance. To close it, open "My Computer/Tools/Folder Options" and select "Use Windows Traditional Folders" in "Web View".

To improve efficiency, you can change the visual effect to "scroll effect" in the "Display/Effect" of the control panel. In addition, it is best not to set the wallpaper, because the wallpaper will take up a lot of memory, and at the same time, it also increases the adjustment time at startup. After the system is installed, you can put "My Documents My Pictures", "C: Windows" and All the image files in the "C: WindowswebWallpaper" directory are deleted, and it is not too late to use the wallpaper. If you don't need it urgently, it's best not to set the screen saver mode.

If you are tired of the fade-in effect of the Win 2000 start menu, select "Roller Program Menu" in the "Start /Settings /Taskbar and Start Menu /Advanced", then right click and select "Properties" /Effect", change the "fade effect" to "scroll effect". To speed up the responsiveness of the start menu, set the item value MenuShowDelay to 0 in HKEY_CURRENT_USERControl PanelDesktop.

5. Reduce startup tasks

Delete all the items in "Program/Start" in the Start menu, and then delete all listed items under the HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrent Version sub-items Run, RunServices, RunServicesOnce, RunOnce, and RunOnceEx. The application, SysTray.exe program should be retained. This ensures that only the SysTray.exe program is started, which reduces the startup task and speeds up the startup process. In addition, if there are sub-items under the "Run" item, you should also delete all the items in the sub-item or simply delete the sub-items as often as the author, which also reduces the number of programs that Windows starts automatically at startup. At the same time, stop the unnecessary service, and also cancel the corresponding program when Windows 2000 starts.

6. Clear Registry Garbage

When installing a software, the system will add some content to the registry accordingly. When the software is deleted, some software registration information is still in the registry, and a large amount of garbage will be formed in the registry in the long run, which seriously affects the running speed and stability of the system. The following methods can be used to clear:

1. Clear the relevant item value data in the registry about uninstalling the application. In KEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionUninstall, delete the sub-items of the uninstalled software.

2. Clear the garbage of the uninstalled software. The garbage is concentrated in HKEY_LOCAL_MACHINESoftware, HKEY_CURRENT_USERSoftware and HKEY_USERS.DefaultSoftware. The contents of these items are basically the same, and the search and delete can be done. In the HKEY_LOCAL_MACHINESoftware branch, find the residual information of the uninstalled software and delete it.

Sometimes for convenience, we can also use the special registry cleaning tool to find the residual information in the registry.
