Before we optimize the system, we must first back up the system to prevent the loss caused by setting settings. ◆ First, the system optimization settings ◆ 1, the system is generally optimized 1) Turn off the special effects in the system properties, this is simple and effective Speed up the prescription. Click Start → Control Panel → System → Advanced → Performance → Settings → In Visual Effects, set to adjust for optimal performance → OK. 2) "My Computer" - "Properties" - "Advanced" - "Error Report" - Select "Disable Error Reporting". 3) Click “Startup and Recovery” - “Settings” to remove the items “Write events to system log”, “send management alarm” and “automatic restart”. Then set "Write Debug Info" below to "None". 4) "My Computer" - "Properties" - "Advanced" - "Performance" - "Settings" - "Advanced", set the virtual memory value to 2.5 times the physical memory, set the initial size and maximum value to the same (For example, your memory is 256M, you can set it to 640M), and set the virtual memory outside the system disk (Note: delete the original file when you move it). 5) Transfer the "My Documents" folder to another partition: Right-click "My Documents" - "Properties" - "Move" and set it to a partition other than the system disk. 6) Transfer the IE temporary folder to another partition: Open IE browser, select "Tools" - "Internet Options" - "General" - "Settings" - "Mobile Folder", set the settings to the partition outside the system disk can. ◆2, speed up the opening and closing of XP 1) First, open the “System Properties” point “Advanced” tab, open “Settings” in the “Startup and Recovery” area, and remove the two “√” in the “System Startup” area. If the multi-system user keeps the "time to display the operating system list". Click "Edit" to make sure that the additional attribute of the startup item is /fastdetect instead of /nodetect. Do not add the /noguiboot attribute first, because guiboot is used later. 2) The next step is very important. Open the “Hardware” tab in “System Properties”, open “Device Manager”, expand “IDE ATA/ATAPI Controller”, double-click to open the “Secondary IDE Channel” property, click The "Advanced Settings" tab, change the transfer mode of devices 1 and 2 to "DMA (if available)", if the device type can select "None", select "None" and click OK to complete the settings. The same method sets the "main IDE channel". 3) Set pre-read to improve boot speed, open the registry, find HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Memory Management\\PrefetchParameters, the right window changes the value of EnablePrefetcher to 1 (0-disable pre-read, 1-read-ahead Application, 2-system starts pre-reading, 3-pre-read both. If the computer is PIII 800MHz or higher, try changing the value to 4 or 5. 4) By the way, the shutdown is also accelerated. Open the registry (Start-Run-regedit), click "My Computer" to open the "Edit" menu, click "Search", enter AutoEndTasks, and click "Find Next". Double-click to open the found result and modify the "Value Data" to 1 (this is the program that causes the system to automatically close and stop responding). Then find HungAppTimeout under AutoEndTasks (set its "Value Data" to 2000 or smaller, recommended to 200), and then find WaitToKillAppTimeout (set its "Value Data" to 2000 or smaller, recommended to 1000). Here, by the way, the menu delay time is also modified. Find the MenuShowDelay under the AutoEndTasks. The value is in milliseconds. If you want to remove the menu delay, set it to 0. After modifying, click the "Edit" menu, open "Find Next" (shortcut F3), continue to search, and modify the results found in the previous step (note: the values should correspond to the same). 5) Use the above method to find WaitToKillServiceTimeout and set the value the same as WaitToKillAppTimeout. 6) After enjoying the fun of the speedy restart, we will further accelerate the startup speed, open the "System Properties" - "Advanced" - "Startup and Recovery" settings, open the editing of the "System Startup" area, add after the fastdetect On /noguiboot, so that scroll bars will not be displayed at startup. If you really like the display of this scroll bar, you don't have to do this step. 7) MsConfig. Select "Run" - "msconfig". What we need to do is the "Startup" tab, click on it, this tab shows all the programs that are running when Windows starts. There is no program here that is life-and-death for Windows, so feel free to remove the unwanted ones. ◆3, reduce the boot disk scan waiting time Select "Start → Run", type "chkntfs /t: 0" in the run dialog box, you can set the disk scan wait time to 0; if you want to ignore the scan when the computer starts For partitions, such as the C drive, you can enter the "chkntfs /xc:" command; if you want to restore the scan of the C drive, you can use the "chkntfs /dc:" command to restore all the default settings of chkntfs, except for the countdown of automatic file check. Outside. ◆ 4, turn off the debugger Dr. Watson Run drwtsn32, remove all but the "dump all thread context". Otherwise, if there is a program error, the hard disk will be loud for a long time, and it will take up a lot of space. If you have encountered this situation before, please find the user.dmp file and delete it, it may save tens of M space. This is the scene of the error program and it is useless to us. Then open the registry, find the HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\AeDebug subkey branch, double-click the Auto key name under it, change its "Value Data" to 0, and finally press F5 to refresh the settings. This completely cancels its operation. In addition, the memory.dmp that appears in the blue screen can also be deleted. In "My Computer → Properties → Advanced → Settings → Write Debug Information → Select None." ◆5, close "system restore" Right click on the "My Computer" on the desktop, select "Properties", find "System Restore" to remove, this can save a lot of space. ◆6. Turn off “Hibernate Support” The hibernation function will take up a lot of hard disk space, so if you use it less, you may want to turn it off. Open the Control Panel - Power Options - Hibernate tab and deselect the Enable Hibernate check box.
