First, open the Advanced tab of System Properties (right-click on My Computer-Properties, or open System in the control panel with the shortcut key win+ pause break), open the Settings in the Startup and Recovery area, and remove the two √ in the System Startup area. If you are a multi-system user, keep "Show Operating System List". Click "Edit" to confirm that the additional attribute of the startup item is /fastdetect instead of nodetect. Don't add the /noguiboot attribute for the time being, because guiboot will be used later.
Remove the two √ in the "System startup" area. The next step is crucial. Open the Hardware tab in the System Properties, open the Device Manager, expand the IDE ATA/ATAPI Controller, double-click to open the Auxiliary IDE Channel property, click the Advanced Settings tab, and change the transfer mode of devices 1 and 2 to DMA (if available).

Windows XP shutdown acceleration optimization
Shutdown acceleration optimization
Open the registry (Start-Run -regedit), click My Computer to open search in the edit menu, enter AutoEndTasks, and click Find Next. Double-click to open the found results, and change the "Numerical Data" to 1. Then you can find HungAppTimeout and WaitToKillAppTimeout under AutoEndTasks, and set "numerical data" below 2000. By the way, you can also modify the menu delay time here and find MenuShowDelay under AutoEndTasks. This value is in milliseconds, and if you want to cancel the menu delay, you can set it to 0. After the modification is completed, click the "Edit" menu to open "Find Next" (shortcut key F3) and install all the results found in the previous method. 2, reduce the time to start the scroll bar Every time you start Windows XP, the blue scroll bar has to go many times. In fact, we can also reduce its scrolling time here to speed up the startup. Open the registry editor, find HKEY _ local _ machine \ system \ current control set \ control \ session manager \ memory management \ prefetch parameter, find the EnablePrefetcher key on the right, and change its default value of 3 to 1, so that the scrolling time of the scroll bar will be reduced. Accelerate the start. When shutting down in XP, the system will send messages to running programs and remote servers, telling them that they should shut down the system, and wait for a response before the system starts to shut down. To speed up the startup, you can set the task to end automatically first. First, find HKEY _ Current _ User \ Control Panel \ Desktop, and set the key value of AutoEndTasks to 1. Then there is a "HungAppTimeout" under this branch, and its value is changed to "4000 (or below), and the default is 50000; Finally, find HKEY _ local _ machine \ system \ current control set \ control \, and also set WaitToKillServiceTimeout to "4000"; Setting the shutdown speed in this way is obviously much faster.
Automatically end the task modification window.
Now, the acceleration of starting and closing the HungAppTimeout modification window has been completed. Restart the computer and feel the feeling of extremely fast startup. Can the scroll bar only turn once or twice?
After enjoying the pleasure of extremely fast restart in the MenuShowDelay modification window, we will further speed up the startup, open the settings of system properties-advanced-startup and fault recovery, open the editing in the "system startup" area, and add /noguiboot after fastdetect, so that the scroll bar will not be displayed when starting. If you like the display of this scroll bar very much, you don't have to do this step.
The related optimization of the second xp
1. Virtual memory
Click "Change" in "Virtual Memory" to set the virtual memory value to 2.5 times of the physical memory, set the initial size and the maximum value to be the same, and set the virtual memory outside the system disk. For example, if your memory is 256M, you can set it to 640, with the operating system installed on drive D and the memory set to drive C. ..
2 accelerate online neighbors
Visiting online neighbors in Windows XP is quite annoying. The system will search its own * * * shared directory, printers that can be used as a network * * *, and planned tasks related to the network, and then it will be displayed. Obviously, this speed will be much slower than in Windows 9x. In fact, we don't use these functions. Instead of using them, we might as well delete them, which will obviously speed up the speed. Open the Registry Editor and find HKEY _ Local _ Machine/Software/Microsoft/Windows/Current Version/Discovery/Remote Computer/Namespace. Delete {2227A280-3AEA-1069-A2DE08002B 30309D} (printer) and {D6277990-4C6A-1F8D87-00060F5 BF} (.
3 Turn off automatic update
"my computer"->; "properties"->; "Automatic update", select "Turn off automatic update and I will update my computer manually"
4. Turn off the system restore function (don't use it if the level is too poor)
"my computer"->; "properties"->; "System Restore", select "Turn off system restore on all drives". You can also turn off system restore for unimportant partitions. If you are concerned about system security, do not turn off the restore function.
5. Turn off Remote Desktop
6 cancel the hibernation function
"my computer"->; "power management"->; "Hibernation", check the box before "Enable Hibernation", about 200MB. "my computer"->; "properties"->; "Remote" and "Allow users to connect to this computer remotely" in "Remote Desktop" are ticked.
7 increase broadband speed
(1) Home Edition: type [regedit] in [Start]-> [Run]-> in [HKEY _ Local _ Machine]-> [Software]->; [strategy]-> [Microsoft]-> [Windows], add a project named [Psched], and add a Dword value [nonbestforlimit] in the window to the right of [Psched]. The numerical data is 0.
(2) Business Edition: The professional edition of Windows XP reserves 20% of the bandwidth by default, which is actually useless for our individual users. It is better to make full use of it than to leave it idle.
Enter gpedit.msc in Start → Run to open the Group Policy Editor. Find "Computer Configuration → Management Template → Network →QoS Packet Scheduler", select "Restrict Reserved Bandwidth" on the right, select "Properties" to open the dialog box of Restrict Reserved Bandwidth, and select "Disable". This releases the reserved bandwidth, which is very useful for friends who surf the Internet.
There is an inference that xp or 2003 has a "reserved bandwidth" of 20%: after it is removed, the speed will increase by 20%, and xp has tampered with the bandwidth. These statements are widely circulated on the internet, but when you spend time and energy to remove this restriction, you find that the speed has not improved!
As far as I know, this method first came from computer newspaper, and today this so-called "skill" is still widely circulated on the Internet. Therefore, I think it is necessary to talk about it here.
Don't just copy things to mislead others. The modified 20% parameter in group policy refers to the maximum bandwidth that a program written with QoS API can use when it needs to access the network. If we set it to 0%, it means that applications written with QoS API will compete with other applications for limited bandwidth, and the possible consequence is that data that needs priority communication will not be given priority. Generally speaking, changing the QoS from 20% to 0% will not only have no benefits, but also lead to the problem that some real-time network applications cannot effectively use network bandwidth.
It is necessary to explain, but I still keep it for your reference!
Actually, there's no need to tear it down.
This 20% bandwidth is not reserved, that is to say, a program using QoS application programming interface (API) can apply for reserving 20% bandwidth on each interface basic link at most, but if this program is not fully utilized, these bandwidths can still be used by other programs.
Microsoft's technical resource planning points out that unless an application specifically requires priority bandwidth, applications running on Windows XP PC can enjoy all network bandwidth. But if the requesting application does not send data, these "predetermined" bandwidths can still be used by other applications. . . . By default, for the basic link on each interface of the terminal system, the total bandwidth that the application can reserve can reach up to 20% of the basic link speed. If the application that reserves the bandwidth does not send enough data to make full use of the bandwidth, the unused part of the reserved bandwidth can still be used for other data streams on the same host.
It can be seen that the so-called 20% reserved bandwidth is purely out of context and misleading.
Don't quite understand
. Delete the options of "writing events to system log", "sending management alarm" and "automatic restart"; Set "Write Debugging Information" to "None";
Turn off the debugger, Dr. Watson.
It seems that I haven't used this thing since the win' 90s. I can cancel it like this: open the book table, find the subkey branch of HKEY _ local _ machine \ software \ Microsoft \ Windows NT \ Current Version \ AE Debug, double-click the Auto key name below it, change its "numerical data" to 0, and finally press F5 to refresh the setting to take effect, thus canceling its operation. Following this idea, we can cancel all options with debugging function, such as memory.dmp that appears when the screen is blue, and "My computer → Properties → Advanced → Settings → Write debugging information → Do not select" and so on.

For QQ suspended animation and other programs that can't run normally under XP, you can find the execution file of the program, right-click it, select the "Compatibility" tab in the pop-up dialog box, and select the corresponding running environment under "Compatibility Mode".
10. Speed up the pre-reading ability and improve the boot speed.
Windows XP pre-reading settings can improve the system speed and speed up the boot. Press Modify to make better use of CPU efficiency: type [regedit]-> [HKEY _ local _ machine] in [Start]-> [Run]->-> [system]-> [Current Control Set]-> [control]-> [Session Manager]-> [MemoryManagement], in the window to the right of [PrefetchParameters], change the numerical data of [enable prefetch] as follows. For example, if you use a CPU with PIII 800MHz or above, it is recommended to change the numerical data to 4 or 5, otherwise it is recommended to keep the numerical data as the default value, that is, 3.
1 1 automatic shutdown stop response program
In [start]-> [run]-> type [registry]-> [HKEY current user]->; [Control Panel]-> [Desktop], change the numeric data of the string value [AutoEndTasks] to 1, and then restart.
12 Automatic shutdown stop response program when shutdown.
Type [Registry]-> [HKEY User]-> in [Start]-> [Run]; [.Default]-> [Control Panel], and then change the numerical data of [AutoEndTasks] to 1 in the window on the right side of [Desktop] to log off or restart.
13. Run the defragmenter when you start the computer.
In [start]-> [run]-> type [regedit]-> [HKEY _ local _ machine]-> [Software]-> [Microsoft]-> [Dfrg]-& gt； [BootOptimizeFunction], set the string value [Enable] to: y equals on, and n equals off.
14 uses the L2 cache of CPU to speed up the overall efficiency.
In [start]-> [run]-> type [regedit]-> [HKEY _ local _ machine]-> [system]-> [Current Control Set]-> [control]-> [SessionManager], in the right window of [MemoryManagement], change the numerical data of [SecondLevelDataCache] to the same decimal value as the L2 cache of CPU: for example, P4 1.6G is 5 12Kb for an L2 cache, and the numerical data is changed to the decimal value of 5 12.
15 Clear the unused DLL files in the memory.
Type [regedit]-> [hkkey _ local _ machine] in [Start]-> [Run]-> [Software]-> [Microsoft]-> [Windows]-& gt； [CurrentVersion], add an item [AlwaysUnloadDLL] in [Explorer], and the default value is set to 1. Note: If the default value is set to [0], this function will be disabled.
16 to speed up the automatic refresh.
In [start]-> [run]-> type [regedit]-> [HKEY _ local _ machine]-> [system]-> [Current Control Set]-> [control]-> [Update], change the numerical data of Dword[UpdateMode] to [0], and then restart.
17 clears unused DLL files in memory.
In hkkey _ local _ machine \ software \ Microsoft \ windows \ currentversion of the registry, add an AlwaysUnloadDLL in Explorer, and the default value is set to 1. Note: If the default value is set to 0, this function will be disabled.
18 automatic shutdown stop response program
Sometimes XP will prompt you that a program stops responding, which is very annoying. By modifying the registry, we can close it ourselves. In HKEY _ Current _ User \ Control Panel \ Desktop, we can change the data whose key value is AutoEndTasks to 1, and then log off or restart. The default value is 0.
19, turn off visual effects.
The user interface of Windows XP is really beautiful, but it consumes a lot of memory. Compared with speed and beauty, we would rather choose the former. Right-click "My Computer", click Properties, click "Advanced", and click "Settings" and "Visual Effects" in the "Performance" column to turn off all special appearance settings here.
20. Turn off the "Internet Time Synchronization" function.
"Internet time synchronization" is to synchronize your computer clock with the Internet time server once a week, so that your system time will be accurate, but this function is of little use to us, and may also cause the problem of crash. So we're going to turn it off.
Specifically, click Start → Control Panel → Date, Time, Language and Region options, and then click Date and Time → "Internet Time.
2 1. No background.
22 modify the run key of the registry,
Cancel a few things that are not commonly used, such as Windows Messenger. Enable Registry Manager: Start → Run → Regedit "HKEY _ Current _ User \ Software \ Microsoft \ Windows \ Current Version \ Run \ MSMSGS "/ Background, right click → Delete, the world is much quieter, and kill those cfmon by the way.

3. Ungroup display: right-click the blank area of the taskbar and select Properties from the pop-up menu. In the pop-up window, uncheck "Group similar taskbar buttons" and confirm.
4. Retrieve the classic login window. Although the default login interface of WinXP is beautiful, if you want to log in with an unlisted user, you will find that there is no way to start. The way to change back to the classic window is to click Start → Control Panel → User Account → Change the login or logout mode of users → Cancel using the check mark in front of the welcome screen, and finally click the application options.

7. Turn off automatic update: right-click my computer, click Properties, click automatic update, and then select Turn off automatic update in the notification settings column. I will update my computer manually.
8. Reduce the waiting time for scanning the startup disk, start → run, and type "chkntfs/t:0".
Then connect to the ms site and upgrade once, even if the optimization is basically completed. For XP, you can use many internal commands to view optimizations. For example, tasklist.exe/SVC can see the actual usage of system services.
Optimizing a system is very troublesome. So we save it and use Ghost to generate a. GHO file so that we can show it to others. Before Ghost, you must do one thing, clear the system hardware, registration and other information, otherwise cloning to different computers will not be able to start. Look for the sysprep.exe file in the Deploy.cab of the Winxp installation disk.
Execute sysprep.exe and select "repackage". You can choose "activate in advance" in the mark below, or you can choose whether to shut down or restart after packaging is completed. After the package is completed, we use GHOst to start from the system disk and use Ghost to generate the backup. Gho mirror, backup complete!
After executing the package and restarting, XP will let us enter the serial number. The method of modifying the serial number mentioned at the beginning of this article is like this.
Introduce xp Quick Start Tool
Q: My computer starts slower than others, and the slow startup of Windows XP is a headache. How to greatly improve the startup speed of Windows XP? A: Relatively speaking, Windows XP is the fastest startup of all Microsoft operating systems, because the kernel of Windows XP can process multiple initialization requests in parallel at startup, and can be pre-read into memory without waiting. At the same time, the system automatically stops. Please don't? /ca & gt；
